This document provides information on Java programming using applets. It discusses that Java can be used to create applications and applets, with the key difference being that applets run within a web browser. The document then covers the basics of how applets work, including their lifecycle of init(), start(), stop(), and destroy() methods. It provides an example "Hello World" applet code and discusses how to compile and run an applet using an HTML file and the appletviewer tool.
An applet is a small Java program that can run in a web browser. It is embedded in an HTML page and downloaded from a server to run on a client computer. Applets have a lifecycle of initialization, startup, running, idle, and destruction. They allow for interactive graphics and animations to be added to webpages but have security restrictions around accessing files and making network connections.
This document provides an overview of Java applets, including:
- Applets are small Java programs that can be transported over the network and embedded in HTML pages.
- The main types of Java programs are standalone programs and web-based programs like applets.
- Applets differ from applications in that they have a predefined lifecycle and are embedded in web pages rather than running independently.
- The Applet class is the superclass for all applets and defines methods corresponding to the applet lifecycle stages like init(), start(), paint(), stop(), and destroy().
- Common methods for applets include drawString() for output, setBackground()/getBackground() for colors, and showStatus() to display in
The document provides an overview of Java applets, including:
- An applet is a small Java program that runs in a web browser within an HTML page. Applets are created by subclassing the Applet class.
- The life cycle of an applet involves initialization, running, display, idle, and destruction states, with corresponding init(), start(), paint(), stop(), and destroy() methods.
- Applets have some restrictions compared to standalone Java applications due to security concerns, such as not being able to access local files.
- Examples are provided for creating a simple "Hello World" applet, embedding an applet in an HTML page, displaying images with applets, and passing
An applet is a small Java program that runs in a web browser. It allows for interactive graphics and animation to be embedded in HTML pages. Applets differ from standalone Java applications in that they have no main method and run within the context of a web page. The lifecycle of an applet involves initialization, starting, stopping, and destruction as the user interacts with the web page. Parameters can be passed to applets using the <param> tag in HTML. The applet code uses methods like init(), paint(), start(), and stop() to control its execution and display output.
An applet is a Java program that runs within a web browser. Applets are embedded in HTML pages and run in a sandbox that prevents them from accessing the local computer's file system for security reasons. When writing an applet, you extend the JApplet class and override certain methods like init(), start(), stop(), destroy(), and paint() that are called at different points in the applet's lifecycle by the browser. The paint() method is used for any drawing or graphics output from the applet.
Applets are Java programs that can be embedded in HTML pages and run in web browsers. An applet's lifecycle involves several method calls: init() is called once to initialize variables; start() restarts the applet after being stopped or loads it initially; paint() redraws the applet's output; stop() suspends threads when the applet is no longer visible; and destroy() removes the applet from memory, freeing resources. Applets allow making websites more dynamic but require the Java plugin and have security restrictions compared to standalone applications.
This document discusses how to build Java applets. It covers when to use applets, how applets work, the features of applets, and the basic steps to create an applet, including writing the applet code, compiling it, designing an HTML page, and testing the applet. It also explains the applet lifecycle and methods like init(), start(), paint(), stop(), and destroy(). The document uses a simple "Hello World" applet example to demonstrate how to write, compile, and display an applet on a web page.
This document provides an overview of Java applets including:
- Applets are programs that run in web browsers under control of the browser to provide interactive experiences on web pages.
- The lifecycle of an applet involves initialization, starting, stopping, and destruction controlled by the browser through specific methods.
- Security restrictions are placed on applets to prevent them from compromising the user's system.

This document provides information on Java applets including:
- An applet is a Java program that runs in a web browser context
- It must extend the Applet class or JApplet class
- Includes the applet lifecycle of loading, creating, initializing, starting, stopping, and destroying
- Provides sample code for creating a basic "MyApp" applet class and embedding it in an HTML page
- Discusses restrictions on applets and demonstrates creating an applet project in NetBeans
This document discusses Java applets and their life cycle. It explains that applets are subclasses of Applet that run in web browsers rather than via a main method. The life cycle of an applet involves initialization, start, paint, stop, and destroy methods. It provides an example "Hello World" applet code and explains how to compile, embed in an HTML file, and run it using an applet viewer. Finally, it contrasts applets and applications, noting that applets have limited system access for security while applications are fully trusted and run via a main method.
An applet is a Java program that runs in a web browser. It can have full Java functionality. Applets have a lifecycle of init(), start(), paint(), stop(), destroy() methods. They are embedded in HTML pages and have security restrictions. The applet displays output using drawString() and requests repaints with repaint(). It can output to the browser status window.
The document discusses input and output streams in Java. It notes that streams represent ordered sequences of bytes with a source or destination. There are two types of streams in Java - character streams and byte streams. The Java IO package provides hierarchies for handling character and byte streams, including classes like Reader, Writer, InputStream and OutputStream. It also discusses concepts like file handling, random access files, and the lifecycle methods of applets like init(), start(), paint(), stop() and destroy().
An applet is a small Java program that runs in a web browser. The document discusses the applet lifecycle, which involves initialization, running, idle, and destruction states. It also covers key applet classes like Applet and Graphics, and methods like init(), start(), stop(), paint(), and destroy() that control an applet's execution. The document provides examples of creating a simple "Hello World" applet using Java code, HTML tags, and testing the applet in a browser.
This document provides information about applet programming in Java. It discusses that applets are small Java programs used primarily for internet computing. Applets can perform tasks like displaying graphics, playing sounds, and accepting user input. Key differences between applets and standalone applications include applets not having a main method, needing to be embedded in an HTML page, and having restrictions on file/network access. The document also covers the applet lifecycle, writing applet code, and using HTML tags to embed applets in web pages.
This document provides an introduction to Java applets, including how they differ from standalone applications, how they are built and used on web pages, and some key classes involved in creating applets. The key points are:
1) Applets are small Java programs that can be embedded in HTML pages and run in web browsers, allowing web pages to have interactive elements, while applications are standalone programs run with the Java interpreter.
2) Applets are built using classes like Applet and JApplet and override methods like init() instead of having a main() method. They are usually graphical and enable user interaction.
3) To create an applet, you define a public class that extends JApplet,
Applets are small Java programs that run in web browsers. They are classified as local or remote based on where they are stored and executed. The applet lifecycle consists of init(), start(), stop(), and destroy() methods that are automatically called during execution. Applets differ from applications in that they are event-driven, run in a browser, and cannot access local files. The HTML <applet> tag is used to embed applets on web pages and supports attributes like code, width, height, and <param> tags for arguments.
This document provides an overview of applets, including:
- Applets are Java programs that run within web browsers. Examples include interactive scientific visualizations and real-time satellite trackers.
- Applets have a lifecycle controlled by the browser via init(), start(), stop(), and destroy() methods. They are also subject to security restrictions since they are downloaded from the web.
- Resources like images, audio, and text files can be accessed from the home server hosting the applet. Communication between the applet and browser is also possible using the AppletContext interface.
Java is a general-purpose; object oriented programming language developed by Sun Microsystems of USA in 1991. This language was initially called “Oak” by James Gosling, but was renamed “Java” in 1995. Java (with a capital J) is a high-level, third generation programming language, like C, Fortran, Smalltalk, Perl, and many others.Java was initially designed to solve on a small scale could also be applied to the Internet on a large scale. This realization caused the focus of Java to switch from consumer electronic to Internet Programming.Java was designed for the development of software for consumer electronic devices like TVs, VCRs, Toasters, Microwaves ovens and such other electronics devices.Java is a first programming language that is not tied to any particular hardware or operating system. Programs developed in Java can be executed anywhere on any system.
Java can be used two types of programs: applications & applets.An application is a program that runs on your computer, under the operating system of that computer.
An applets is an application designed to be transmitted over the Internet and executed by a java-compatible Web Browser. An applet is an executable program that runs inside a browser, such as Netscape or Internet Explorer.
- Applets are small Java applications that run within web browsers. They are embedded in HTML pages and can interact with the user.
- Applets follow an event-driven model where the AWT notifies the applet of user interactions. The applet then takes action and returns control to the AWT.
- The applet lifecycle includes init(), start(), stop(), and destroy() methods that are called at different points as the applet loads and runs within the browser.

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.

Diptera: The Two-Winged Wonders, The Fly Squad: Order Diptera.pptxArshad Shaikh
Diptera, commonly known as flies, is a large and diverse order of insects that includes mosquitoes, midges, gnats, and horseflies. Characterized by a single pair of wings (hindwings are modified into balancing organs called halteres), Diptera are found in almost every environment and play important roles in ecosystems as pollinators, decomposers, and food sources. Some species, however, are significant pests and disease vectors, transmitting diseases like malaria, dengue, and Zika virus.

2. Revision
1. Explain exception handling in Java.
2. List the types of exceptions in Java
language.
3. What are try, catch and throw blocks
used for?
3. Objectives
At the end of this presentation, you will be able to :
• Explain applet programming
• List the differences between applications and
applets
• Describe the different stages in the life cycle of
an applet
4. Java Programs
Java supports two kinds of programs.
• Java Applications are the normal standalone
programs.
• Java Applets are the programs that are to be
embedded in a Web page.
5. Applet Programming
• Applets are the Java programs that are
executed by the Web browser.
• Appletviewer is a Java utility to execute
applets.
• Applet is a special class file written to display
graphics in a Web browser.
6. Applets
• Applets are embedded in Web pages using
the HTML tag <APPLET>.
• When a Web page containing applet program
is run, it is downloaded to the memory
automatically and executed by the Web
browser.
• Applet gets displayed in the specific space
allocated in the Web page called Applet
Window.
7. Applets
Applets can contain embedded objects like :
• Animated graphics
• Video games
• Advanced text displays and images
• Audio
8. Applet Types
• Local Applets
Applets that are stored in the local machine
• Remote Applets
Applets that are stored in a remote computer.
These can be downloaded and embedded into Web
pages from the Internet.
11. Applets Vs. Applications
Applets Applications
Applets are embedded in
Web pages and cannot be
run independently.
Applications can be
run independently.
Applet programs call certain
methods such as init(),
start(), stop(), and destroy()
of Applet class to start and
execute the applet code.
Programs use the
main() method for
initiating the
execution of the
code.
12. Applets Vs. Applications (Contd..)
Applets Applications
Applets cannot read from or
write to the files in the local
computer.
Applications can
read from or write
to local computer.
Applets enable the user to
interact graphically.
Applications do not
enable the user to
interact graphically.
13. Life Cycle of Applets
The four methods executed are :
1. init()
2. start()
3. stop()
4. destroy()
15. init()
Initialisation State
• This method is executed when it is first
loaded into the memory.
• The applet is now said to exist in the
initialisation state.
17. start()
Running State
• The start() method of the Applet Class is
executed whenever an applet is started or
restarted.
• The applet is now said to exist in the running
state.
19. stop()
Idle State
• The stop() method is executed when an applet is
closed.
• The applet is stopped automatically when the user
switches to another program or Web page.
• This can also be done by invoking explicitly the
stop() method of Applet class.
• When this is invoked the applet enters the idle
state.
23. paint()
• The paint() method of the Applet class is
executed automatically whenever the applet
is displayed in the Web page.
• This method is used to draw graphics in the
drawing area of the applet.
24. repaint()
• The repaint() method is used whenever you
want to redraw the applet’s drawing area.
• The repaint() method calls the update()
method.
• The update() method clears the applet area
and calls the paint() method.
26. Summary
In this presentation, you learnt the following
• Applets are Java programs mainly used in
Internet computing.
• The applet’s output is displayed within a subset
of the display area of the browser.
• Java applet inherits a set of default properties
from the Applet class.
• An applet enters the Initialisation state when it is
first loaded.
27. Summary
In this presentation, you learnt the following
• Applet enters the running state when the start()
method of Applet class is invoked.
• An applet becomes idle when it is stopped from
running.
• An applet is said to be dead when it is removed
from memory.
28. Assignment
1. Define an applet. List the uses of applets.
2. Sketch and explain the life cycle of an
applet.
