1) Variables are used to store and represent data in a program. They have a name, data type, and range of values. Variable names must follow specific identifier rules.
2) Classes define the attributes (data) and behaviors (methods) of objects. An object is an instance of a class. Constructors are special methods that initialize new objects.
3) Constructors allow objects to be created and initialized with specific attribute values. Defining multiple constructors provides flexibility in how objects are instantiated.
This document discusses objects and classes in Java. It begins by defining what a class is - a template that defines common properties of objects. Everything in a Java program must be encapsulated within a class. A class defines an object's state via fields and behavior via methods. The document then discusses how to define classes by specifying fields, methods, and constructors. It provides examples of creating objects from classes and accessing object members. The document also covers key object-oriented programming concepts like encapsulation and inheritance.
This document provides an overview of object-oriented programming concepts in Java including classes, objects, attributes, and methods. It discusses how classes define templates for objects and how objects are instances of classes. Examples are given of declaring a class for a car with attributes like make and speed, and methods like accelerate and turn. The document also covers creating objects from classes in code, and accessing object attributes and methods. Finally, it briefly introduces some standard Java classes like Math that are commonly used.
The document discusses object-oriented programming concepts like classes, objects, inheritance, encapsulation, and composition. It provides examples of how these concepts can be implemented in Java. It explains that a class defines common attributes and behaviors of objects, while an object is an instance of a class. Inheritance allows classes to extend and override methods of parent classes. Encapsulation involves making attributes private and accessing them via getter/setter methods. Composition refers to objects having other objects as members.
Classes and objects are fundamental concepts in object-oriented programming. A class defines common properties and behaviors of objects through fields and methods. An object is an instance of a class that represents a real-world entity with state (fields) and behavior (methods). Classes can inherit properties and behaviors from superclasses and implement interfaces. Objects are created from classes using constructors.
This document provides an introduction and overview of Java programming concepts including:
- Java can be used to create dynamic web applications, native applications, and is not the same as JavaScript.
- The basic structure of a Java program includes object-oriented concepts like classes, objects, inheritance. Development environments like Eclipse help facilitate Java development.
- Variables represent object state and methods represent object behavior. Classes are templates that define common attributes and behaviors of objects.
- Eclipse is an integrated development environment used for Java development which allows editing, compiling and running Java programs.
The document discusses key concepts in Java including classes, objects, methods, and command line arguments. A class defines common properties and behaviors for objects through fields and methods. Objects are instantiated from classes and can access fields and methods using dot notation. Command line arguments allow passing data into a Java application and are accessed through the args parameter in the main method.
The document discusses key concepts of object-oriented programming with Java including classes, objects, encapsulation, inheritance, and polymorphism. It defines a class as a blueprint for objects and notes that objects are instances of classes that contain attributes and methods. The document explains that encapsulation groups related data and methods into a class and hides implementation details. Inheritance and polymorphism allow classes to share and extend behaviors from other classes. Constructors, methods, and the 'this' keyword are also covered.
Java uses an object-oriented approach where data and methods are bundled together as objects. A class defines the common attributes and behaviors of a group of objects. Individual objects are instantiated from classes and can interact by sending messages that invoke each other's methods. Encapsulation hides an object's internal data within itself and controls access via public methods.

Individual objects are instantiated from classes and can interact by sending messages that invoke each other's methods. Encapsulation hides an object's internal data within itself and controls access via public methods.
A class is a template that defines the form of an object. It specifies both the data and code that will operate on that data. Objects are instances of classes. The data and code that constitute a class are called members or instance variables. A class definition creates a new data type. Objects are created using the new operator, which dynamically allocates memory and returns a reference to the new object. Constructors initialize objects when they are created and can be used to assign initial values to data members. Methods manipulate the data defined by the class and can accept parameters. The garbage collector automatically reclaims memory occupied by objects no longer being used to prevent memory leaks.
The document discusses defining classes and objects in Java. It covers defining simple classes, class elements like fields and methods, constructors, properties, static members, and using classes by creating instances and calling methods. Key points include classes define the structure of objects, constructors initialize object state, properties encapsulate fields, and static members are associated with a class not individual objects.
This document provides an overview of object-oriented programming concepts including abstraction, encapsulation, classes, objects, methods, constructors, inheritance, polymorphism, and interfaces. It explains that classes act as blueprints for objects, describing their data and behaviors. Objects are instances of classes that have state stored in attributes and behaviors defined by methods. Key features of OOP like inheritance, encapsulation, and polymorphism are discussed at a high level.
The document discusses the concept of object-oriented programming (OOP) in Java. It defines key OOP concepts like objects, classes, inheritance, interfaces, encapsulation, instantiation, and initialization. Objects have characteristics and behaviors, and classes define common characteristics for groups of objects. Inheritance allows subclasses to inherit properties from parent classes. Interfaces define methods without implementing them. Instantiation creates object instances from classes using the new keyword. Constructors initialize objects, and initialization assigns initial field values. Examples in Java syntax are provided to illustrate these concepts.
The document discusses object-oriented concepts in Java including objects, classes, constructors, encapsulation, and Java source file layout. It defines objects as anything real or conceptual and classes as blueprints for objects. Constructors are special methods that initialize objects. Encapsulation hides implementation details and protects data using private attributes with public getters and setters. The Java source file layout follows a PIC order of package, import, classes. It also discusses creating JAR files to package related class files together.
The document discusses key concepts of object-oriented programming (OOP) in Java, including objects, classes, inheritance, polymorphism, abstraction, and encapsulation. It provides examples of classes like Student and Rectangle to demonstrate how objects are instantiated from classes and how methods can access and modify object attributes.
In this chapter we will understand how to define custom classes and their elements. We will learn to declare fields, constructors and properties for the classes. We will revise what a method is and we will broaden our knowledge about access modifiers and methods.
This tutorial will help you to understand about Java OOP’S concepts with examples. Let’s discuss about what are the features of Object Oriented Programming. Writing object-oriented programs involves creating classes, creating objects from those classes, and creating applications, which are stand-alone executable programs that use those objects.
The document discusses a lecture on object-oriented programming. It covers key topics like classes, objects, fields, methods, constructors, and creating objects from classes. It provides examples of how to define classes with fields, methods, and constructors. It also explains how to compile and run a simple Java program with a main method.
This document provides an introduction to the Java programming language. It discusses the history and components of Java, including the Java language, platform, and tools. It then explains some key Java concepts like object-oriented programming, classes, objects, inheritance, and interfaces. It provides examples of how to write a simple Java program and declare methods. It also compares static and instance members and discusses abstract classes and when to use interfaces versus abstract classes.
Object-oriented programming (OOP) is a programming paradigm based on objects and classes. The primary purpose of OOP is to increase flexibility and maintainability by structuring a program around reusable pieces of code (classes) that are used to create individual instances (objects). A class defines the variables and methods that characterize objects of a certain kind. For example, a Car class could define characteristics like wheels, a steering wheel, etc. that all car objects would share. Objects are instantiated from classes using the new keyword in Java.

In the seventh century, the rule of Sindh state was in the hands of Rai dynasty. We know the names of five kings of this dynasty- Rai Divji, Rai Singhras, Rai Sahasi, Rai Sihras II and Rai Sahasi II. During the time of Rai Sihras II, Nimruz of Persia attacked Sindh and killed him. After the return of the Persians, Rai Sahasi II became the king. After killing him, one of his Brahmin ministers named Chach took over the throne. He married the widow of Rai Sahasi and became the ruler of entire Sindh by suppressing the rebellions of the governors.
Sustainable Innovation with Immersive LearningLeonel Morgado
Prof. Leonel and Prof. Dennis approached educational uses, practices, and strategies of using immersion as a lens to interpret, design, and planning educational activities in a sustainable way. Rather than one-off gimmicks, the intent is to enable instructors (and institutions) to be able to include them in their regular activities, including the ability to evaluate and redesign them.
Immersion as a phenomenon enables interpreting pedagogical activities in a learning-agnostic way: you take a stance on the learning theory to follow, and leverage immersion to envision and guide your practice.

Chaulukya or Solanki was one of the Rajputs born from Agnikul. In the Vadnagar inscription, the origin of this dynasty is told from Brahma's Chauluk or Kamandalu. They ruled in Gujarat from the latter half of the tenth century to the beginning of the thirteenth century. Their capital was in Anahilwad. It is not certain whether it had any relation with the Chalukya dynasty of the south or not. It is worth mentioning that the name of the dynasty of the south was 'Chaluky' while the dynasty of Gujarat has been called 'Chaulukya'. The rulers of this dynasty were the supporters and patrons of Jainism.

PEST OF WHEAT SORGHUM BAJRA and MINOR MILLETS.pptxArshad Shaikh
Wheat, sorghum, and bajra (pearl millet) are susceptible to various pests that can significantly impact crop yields. Common pests include aphids, stem borers, shoot flies, and armyworms. Aphids feed on plant sap, weakening the plants, while stem borers and shoot flies damage the stems and shoots, leading to dead hearts and reduced growth. Armyworms, on the other hand, are voracious feeders that can cause extensive defoliation and grain damage. Effective management strategies, including resistant varieties, cultural practices, and targeted pesticide applications, are essential to mitigate pest damage and ensure healthy crop production.

2. Experiment No: 01 Mapping: CO1 and CO2
Experiment Name Class & Object
Experiment Details:
Class:
A class in Java is a blueprint or template used to create objects. It defines properties (attributes) and behaviors
(methods) that the objects of the class will have. Think of a class as a prototype for creating similar entities.
Real-World Example
Consider the concept of a Car. Every car shares attributes like brand, model, color, speed, and behaviors like
start, stop, and accelerate. The class car would define these attributes and behaviors.
Object:
An object is an instance of a class. It represents a specific entity with a state (attributes) and behavior
(methods). Objects are created using the new keyword in Java.
Real-World Example
A specific car, like a red Toyota Corolla, is an object of the class Car. This object will have specific values for
its attributes, like color: red, brand: Toyota, and model: Corolla, and can perform behaviors like start, and
accelerate.
Code:
//file Name : Main
class Car {
String brand;
String model;
String color;
int speed;
Car(String brand, String model, String color, int speed) {
this.brand = brand;
this.model = model;
this.color = color;
this.speed = speed;
}
3. void start() {
System.out.println(brand + " " + model + " is starting.");
}
void accelerate(int increment) {
speed += increment;
System.out.println(brand + " " + model + "Current speed: " + speed + "
km/h");
}
void stop() {
System.out.println(brand + " " + model + " has stopped.");
speed = 0;
}
}
public class Main {
public static void main(String[] args) {
Car car1 = new Car("Toyota", "Corolla", "Red", 0);
Car car2 = new Car("Tesla", "Model 3", "Blue", 0);
car1.start();
car1.accelerate(60);
car1.stop();
car2.start();
car2.accelerate(80);
car2.stop();
}
}
Obtained Output:
Toyota Corolla is starting.
Toyota Corolla Current speed: 60 km/h
Toyota Corolla has stopped.
Tesla Model 3 is starting.
Tesla Model 3Current speed: 80 km/h
Tesla Model 3 has stopped.
Desired
Output?
YES
