What Is an Abstract Class?
Abstract class in Java is considered as a template of
methods and variables used in a program. Abstract classes
cannot be instantiated directly.

Features of Abstract class
Template
Loose Coupling
Code Reusability
Abstraction
Dynamic Resolution

Rules to Declare an Abstract Class
• The keyword “abstract” is mandatory.
• Abstract classes cannot be instantiated.
• An abstract class must have at least one abstract method.
• An abstract class includes final methods.
• An abstract class may also include non-abstract methods.
• Abstract class can include constructors and static methods.

Procedure to Achieve Abstraction
Procedure

Procedure to Achieve Abstraction
Abstraction is one of the fundamentals of Object-oriented
programming. Abstraction can be achieved by following either of the
two below mentioned procedures.
• Using an Interface
• Using an Abstract Class
Procedure

Syntax of Abstract Class
Abstraction can be achieved by following the syntax mentioned below.
abstract class Simplilearn{}
abstract void Simplilearn();

Interface
Interface can be defined as a boundary between the method and the class
implementing it. In Java, we use interface to achieve abstraction

Syntax of Interface
Abstraction can be achieved by following the syntax mentioned below.
interface Simplilearn{}

Interface V/S Abstract Class
I
Interface Abstract
Keyword: interface Keyword: abstract
Subclasses extend it Subclasses implement it
Only one abstract class
can be extended
Multiple interfaces can be
implemented
Supports multiple
inheritance
Does not support
multiple inheritance

Advantages of Abstract Class
• Highly beneficial in writing shorter codes
• Avoids code duplication
• Enables code Reusability
• Changes to Internal code implementation is done without affecting
classes

Disadvantages of Abstract Class
• Abstraction is expensive as sometimes you need to handle cases and
situation which are not necessary sometimes.
• Object relational impedance mismatch in case of RDBMS
• Object relational Mapping in case of Frameworks like hibernate

The Composite pattern allows hierarchical tree structures to be composed of objects. It allows clients to treat individual objects and compositions of objects uniformly. In the given document, the Composite pattern is described for representing graphical objects in a drawing editor. Graphic is an abstract component class that represents both individual graphical primitives like lines and text as well as container graphics like pictures. This allows clients to treat both types of graphics uniformly. The pattern provides structure for composing objects into tree structures and defines roles like component, leaf, and composite. It offers benefits like simplifying client code and making it easy to add new component types.

SOLID Principles and The Clean ArchitectureMohamed Galal

06 abstract-classesAnup Burange

This document discusses abstract classes and interfaces in Java. It explains that abstract classes can contain abstract methods that subclasses must implement. Interfaces also declare methods but do not provide implementations - classes that implement interfaces must define those methods. The document provides examples of abstract classes and interfaces, and how they allow classes to fulfill multiple roles by implementing multiple interfaces. It also discusses adapter classes that implement interfaces but provide empty method bodies that subclasses can override selectively.

Patterns in EclipseMadhu Samuel

The document discusses various design patterns used in software development with Eclipse, including creational, structural, and behavioral patterns. It provides examples of how patterns like singleton, observer, strategy, composite, proxy, visitor, memento, and adapter are applied in Eclipse for tasks like managing global access points, responding to changes, customizing behavior, defining object relationships, and separating interfaces from implementations. The goal of using these patterns is to create loosely coupled systems that are flexible and able to handle change.

Introduction to Design Patterns and SingletonJonathan Simon

InheritancePranali Chaudhari

The document discusses various concepts related to inheritance in C++ including types of inheritance (single, multiple, hierarchical, multilevel, hybrid), defining derived classes, visibility modes (private, public), constructors and destructors in derived classes, virtual base classes, virtual functions, pure virtual functions, and abstract base classes. It provides examples and explanations for each concept.

TypeScriptFabian Vilers

TypeScript is a superset of JavaScript that compiles to JavaScript. It adds optional static types, classes, and modules to JavaScript to enable scalable application development. TypeScript starts with and compiles to idiomatic JavaScript, so it runs in any browser or host on any OS. The TypeScript type system formalizes JavaScript's dynamic types through static representation and type inference, requiring few type annotations in practice. Classes and modules in TypeScript structure applications clearly and align with emerging ECMAScript standards. The open source TypeScript compiler and tooling like Visual Studio and Resharper support provide full static typing of libraries and source maps.

Basic design pattern interview questionsjinaldesailive

Design patterns are reusable solutions to common programming problems. The Gang of Four (GoF) authored the seminal book on design patterns, identifying 23 patterns divided into creational, structural and behavioral categories. Creational patterns provide object creation mechanisms, structural patterns manage object relationships, and behavioral patterns define communication between objects. Design patterns can be further divided into class and object patterns based on whether relationships are defined at compile-time or run-time.

Flyweight patternShakil Ahmed

The document discusses the flyweight pattern, which uses sharing to efficiently support large numbers of fine-grained objects. An application may use many objects, but most objects' state can be made extrinsic. By removing extrinsic state and replacing groups of objects with relatively few shared objects, storage costs can be reduced. The flyweight pattern defines an interface for flyweights to receive extrinsic state, with concrete flyweights implementing storage for intrinsic state. A flyweight factory manages the shared flyweight objects.

ADO .Net DrSonali Vyas

This document discusses ADO.NET, which is a data access technology that allows applications to connect to and manipulate data from various sources. It describes the core ADO.NET objects like Connection, Command, DataReader, DataAdapter, DataSet and DataTable. It also explains the differences between connected and disconnected data access models in ADO.NET, detailing the objects used in each approach and their advantages. Finally, it provides an overview of commonly used .NET data providers like SqlClient, OleDb and Odbc.

AWT Packages , Containers and ComponentsSohanur63

The AWT package provides basic graphics tools for Java applications. It contains classes like Container, Component, Button, Label, etc. that allow creating and managing GUI elements. Containers can hold and display Components. Components are user interface elements like buttons and text fields. Containers are also Components, allowing nesting. The example code creates a Frame container with a Panel child container holding a Label, TextField, and Button component.

Introduction to Spring's Dependency InjectionRichard Paul

This document provides an overview of dependency injection in Spring. It defines dependency injection as a form of inversion of control where objects are provided to classes rather than having classes create their own dependencies. It discusses the benefits of dependency injection such as loose coupling, easy switching of implementations, and enhanced testability. It also compares constructor injection and setter injection and describes how to configure dependency injection using XML, annotations, and Java configuration in Spring.

Java Spring FrameworkMehul Jariwala

Frameworks are large prewritten code to which you add your own code to solve a problem in a specific domain. You make use of a framework by calling its methods,inheritance,and supplying “call-backs” listeners. Spring is the most popular application development framework for enterprise Java™. Millions of developers use Spring to create high performing, easily testable, reusable code without any lock-in.

Microservices Platform with Spring Boot, Spring Cloud Config, Spring Cloud Ne...Tin Linn Soe

This document provides an overview of microservices architecture using Spring Boot, Eureka, and Spring Cloud. It describes using Spring Boot for cloud-native development, Eureka for service registration and discovery, Spring Cloud Config for distributed configuration, Zuul proxy for API gateway, Feign for communication between services, Sleuth for distributed request tracing, and demonstrates a sample application with three microservices that register with Eureka and fetch configurations from Config Server while communicating through Feign and tracing logs with Sleuth. Diagrams and code snippets are presented to illustrate the concepts and architecture.

SOLID Design PrinciplesAndreas Enbohm

The document discusses the SOLID principles of object-oriented design: 1. The Single Responsibility Principle states that a class should have one, and only one, reason to change. 2. The Open-Closed Principle states that software entities should be open for extension but closed for modification. Behavior is changed through inheritance and composition rather than direct modification. 3. The Liskov Substitution Principle states that subclasses must behave in the same way as the base class so that the base class can be substituted wherever the subclass is expected. 4. The Interface Segregation Principle states that interfaces should be small and focused so that client classes do not depend on methods they do not use.

Design Pattern - Observer PatternMudasir Qazi

Concurrency in JavaAllan Huang

The document discusses key concepts related to threads and concurrency in Java. It defines processes, threads, and the Java memory model. It then covers various concurrency utilities in Java like synchronized blocks, volatile fields, atomic classes, thread pools, blocking queues, and locking mechanisms like ReentrantLock. The last part discusses high-level concurrency constructs like semaphores, latches, barriers, and phaser.

Proxy Design PatternAnjan Kumar Bollam

The Proxy design pattern provides a surrogate or placeholder for another object to control access to it. A proxy can act as a placeholder for complex, expensive objects that should not be initialized until needed. This delays the creation of these objects until they are actually required. Proxies can also protect the real component from undue complexity or provide extra functionality. Some common uses of proxies include remote proxies for objects in a different address space, virtual proxies that create objects on demand, and protection proxies that control access to the original object.

Spring Data JPACheng Ta Yeh

The document provides an overview and introduction to Spring Data JPA, including: 1) How Spring Data abstracts away basic data management concepts and supports both relational and non-relational databases. 2) An example of refactoring from plain JPA to Spring Data JPA by defining a repository interface and using built-in query methods. 3) How the Spring Data repository abstraction reduces the effort to implement data access layers through interfaces like Repository.

The Singleton Pattern PresentationJAINIK PATEL

The Singleton pattern ensures that only one instance of a class is created, and provides a global access point to that instance. There are many objects that only need a single instance, such as thread pools, caches, and objects used for logging or managing preferences. The Singleton pattern solves problems that could occur from instantiating multiple instances of these objects, such as inconsistent behavior or wasted resources. It works by having a class define a static method that returns its sole instance, which is created the first time the method is called.

Domain Driven Design (DDD)Tom Kocjan

Domain Driven Design (DDD) is a software design approach that focuses on modeling a domain accurately. It uses ubiquitous language, bounded contexts, and explicit domain models. The key aspects of DDD include developing a shared model with domain experts, separating concerns into bounded contexts, and iteratively refining domain models through close collaboration between technical and domain teams. DDD aims to produce software designs that are more aligned with the mental models of users and stakeholders in a complex domain.

Factory Design PatternJaswant Singh

Design patterns are general reusable solutions to common problems in software design. They are not specific designs that can be transformed directly into code, but descriptions that can be applied to many situations. In 1994, the "Gang of Four" authors published the influential book Design Patterns, which introduced design patterns to software development. The book categorized patterns into creational, structural, and behavioral groups. Factory pattern is a creational pattern that provides a way to create objects without exposing object creation logic to the client. It allows for more flexibility in deciding which objects need to be created.

Iterator Design PatternVarun Arora

The Iterator pattern provides a way to access the elements of an aggregate object sequentially without exposing its underlying representation. It defines an interface for traversing elements and concrete iterators that implement this interface and keep track of the current position. The iterator pattern is useful for hiding complexities of different traversal methods and supporting multiple traversals of the same collection simultaneously.

Git Rebase vs MergeMariam Hakobyan

Git rebase rewrites commit history by cutting commits from one branch and applying them to another branch, changing the commit IDs. This cleans up history but can cause issues if commits are pushed. Git merge keeps the original commits and adds a merge commit, keeping full history but potentially cluttering it. Rebase is best for local branches before pushing, while merge is better for integrating public branches to avoid rewriting shared history.

Java abstract Keyword.pdfSudhanshiBakre1

Abstract classes in Java are used as templates for creating concrete classes and cannot be instantiated directly. They provide a common interface and implementation for subclasses through abstract and concrete methods. For example, an abstract Shape class can define methods like getColor() while making getArea() abstract, requiring subclasses like Circle to implement it. Abstract classes allow for code reuse and polymorphism, serving as a blueprint for related classes to customize as needed.

1. The document discusses abstraction, abstract classes, and interfaces in object-oriented programming and Java. It provides examples of declaring abstract classes with abstract methods and subclasses implementing those methods. 2. It also discusses interfaces and how classes can implement interfaces by providing implementations for the interface's abstract methods. 3. The examples create abstract classes like Animal and Shape3D and interfaces like Shape. Subclasses and classes that implement the interfaces override the abstract methods to provide class-specific behavior.

ABSTRACT CLASSES AND INTERFACES.pptJayanthiM15

Abstract classes in Java can have both abstract and non-abstract methods. They cannot be instantiated and must be extended. Abstract methods do not have a method body. Interfaces in Java provide full abstraction and contain only abstract method declarations. Classes implement interfaces to inherit their methods. Both abstract classes and interfaces allow for abstraction and multiple inheritance in Java.

Abstraction in Java: Abstract class and InterfacesJamsher bhanbhro

In my presentation titled "Abstraction in Java," I have discussed the fundamental concept of abstraction in Java programming. The presentation delves into how abstraction is a key principle in object-oriented programming, explaining its role in hiding the complexity of code while exposing only the necessary details. It includes examples and explanations on implementing abstraction in Java, offering a clear understanding for both beginners and intermediate learners. This presentation serves as an educational guide for those interested in enhancing their Java programming skills and understanding the practical applications of abstraction in software development.

Abstraction in java.pptxAsifMulani17

Abstraction in Java allows hiding implementation details and exposing only essential properties and behaviors to users. This is achieved through abstract classes and interfaces. Abstract classes can contain both abstract and concrete methods, while interfaces contain only abstract methods. Any subclass of an abstract class must implement all abstract methods to be instantiable, or itself be declared abstract. Abstract classes allow partial implementation to be inherited and completed in subclasses.

what is differance between abstract class and interface pptmanojsharma469262

Abstract Classes vs. Interfaces: Choosing the Right Path in Object-Oriented Programming When it comes to OOP, choosing between abstract classes and interfaces is not a decision to be taken lightly. It's essential to understand the nuances of both options to make an informed choice. Abstract classes provide a blueprint for related classes, while interfaces define a set of behaviors that classes can implement. These subtle differences can have a significant impact on the overall structure and functionality of your code. Understanding Abstract Classes Hey, have you heard about abstract classes in object-oriented programming? They're like the foundation of OOP, providing a template for similar classes to share common features. But unlike regular classes, you can't create an instance of an abstract class by itself. Instead, it's just there to give a head start to other classes that come after it. It's kind of like a family tree, where the abstract class is the grandparent and the subclasses are the children and grandchildren. They all share similarities, but each one has their own unique traits too. Cool, right? Embracing Interfaces So I wanted to discuses with you about interfaces. Basically, an interface is like a contract or an agreement between two different parts of a program. It outlines what each part is responsible for and how they'll communicate with each other. Think of it like this: You and I are each parts of a program. If we want to work together, we need to agree on certain things, like who will do what tasks and how we'll share information. That's what an interface does for different parts of a program. It helps them work together smoothly and efficiently. So, why should we care about interfaces? Well, they're important because they allow different parts of a program to be developed and tested independently. This means that if one part needs to be changed or updated, it won't necessarily affect the other parts. Plus, interfaces make it easier for different developers to work on different pieces of a program at the same time. Overall, interfaces might seem a bit technical, but they're really just a way for different parts of a program to talk to each other and work together effectively. Cool, right? Choosing the Right Path So, when it comes to choosing between abstract classes and interfaces, it's not just a random decision. There are a few things you should think about before making your choice. you can find here a ppt about what is differance between abstract class and interface in java,differance between abstract class and interface,how can you define abstract class and interface

Abstract methodYaswanth Babu Gummadivelli

An abstract class is a class that is declared with the abstract keyword and cannot be instantiated. It serves as a base for subclasses to inherit its members and provide implementations. Abstract classes can contain abstract and non-abstract members, where abstract members only specify their signature in the abstract class and must be implemented in subclasses. Subclasses must implement all abstract members to be instantiated.

java-06inheritanceArjun Shanka

1. Inheritance in Java allows classes to extend other classes and interfaces to implement other interfaces. This allows code reuse and establishes type constraints. 2. Abstract classes can contain both abstract and non-abstract methods while interfaces contain only abstract methods. Interfaces establish contracts that implementing classes must follow. 3. When constructing objects with inheritance, superclass constructors are called before subclass constructors. Abstract classes and interfaces allow incomplete implementations to be extended.

The document discusses abstract classes, abstract methods, and interfaces in object-oriented programming. It defines abstract classes as classes declared with the abstract keyword that can contain both defined and undefined methods. Abstract methods only contain declarations without a body. Interfaces are similar to classes but can only contain abstract methods and final static variables. The key differences between interfaces and classes are that interfaces cannot be instantiated, do not have constructors, and all methods are implicitly abstract. Interfaces are used to achieve abstraction and multiple inheritance in Java.
