Steps for Writing Applet Program

-

 Here are the basic steps for writing an applet program:

  1. Create a new Java file: Create a new Java file using a text editor, such as Notepad, and save it with a .java extension. For example, you might call it "MyApplet.java".

  2. Declare the applet class: At the beginning of your Java file, declare the applet class by typing "public class" followed by the name of your class (in this case, "MyApplet") and "extends Applet". This tells the compiler that you are creating an applet.

  3. Override the init() method: Inside your applet class, you will need to override the init() method. This method is called when the applet is first loaded and is used to initialize the applet's variables and set up its user interface.

  4. Override the paint() method: Next, you will need to override the paint() method. This method is called whenever the applet needs to be redrawn, such as when the user resizes the window or when the applet's state changes.

  5. Write the applet code: Write the code for your applet, including any graphics or user interface components that you want to display.

  6. Compile the applet: Once you have finished writing your code, compile the applet by typing "javac MyApplet.java" in the command prompt. This will generate a .class file containing your compiled code.

  7. Embed the applet in a web page: To use your applet in a web page, you will need to create an HTML file and embed the applet within it using the <applet> tag.

  8. Test the applet: Open your HTML file in a web browser to test your applet. If everything is working correctly, you should see your applet displayed within the web page.



To run an applet in Java, you need to follow these steps:

  1. Create an HTML file: Create an HTML file that includes the <applet> tag. This tag specifies the location of the applet code and any parameters that need to be passed to the applet.

  2. Compile the applet: Compile the applet code using the Java compiler (javac). This will create a .class file containing the compiled code.

  3. Deploy the applet: Place the compiled .class file in the same directory as the HTML file that you created in step 1. This allows the web browser to find the applet code when the HTML file is opened.

  4. Open the HTML file in a web browser: Open the HTML file in a web browser to view the applet. The applet should be displayed within the web page.

Here is an example of an HTML file that includes an applet tag:

html
<html>
<head>
<title>My Applet</title>
</head>
<body>
<applet code="MyApplet.class" width="200" height="200">
</applet>
</body>
</html>

In this example, the applet code is specified using the "code" attribute of the <applet> tag. The "width" and "height" attributes specify the size of the applet in pixels. When you open this HTML file in a web browser, the applet will be loaded and displayed within the web page.

Cryptography API

-
Java offers a comprehensive set of cryptographic functionalities through its `java.security` package. This package provides various classes and interfaces for encryption, decryption, key generation, digital signatures, and more. Here are some key classes and concepts within Java's Cryptography API: 1. **Message Digests (Hashing):** Classes like `MessageDigest` help generate hash values for data using algorithms like MD5, SHA-1, SHA-256, etc. 2. **Encryption/Decryption:** The `Cipher` class allows encryption and decryption using various algorithms like AES, DES, RSA, etc. 3. **Key Management:** Java provides classes such as `KeyGenerator` for generating symmetric keys, `KeyPairGenerator` for key pairs (for asymmetric encryption), and `KeyStore` for managing keys and certificates. 4. **Digital Signatures:** The `Signature` class helps create and verify digital signatures. Here's a simple example demonstrating encryption and decryption using Java's Cryptography API: ```java im...

Java Applet Overview

-
  An applet in Java is a special type of program that is designed to be executed within a web browser. Applets are written in the Java programming language and can be embedded within an HTML page using the <applet> tag. When the HTML page containing the applet is loaded in a web browser, the applet code is downloaded and executed by the Java Virtual Machine (JVM) built into the browser. Applets are often used to provide interactive functionality on a web page, such as games, animations, and data visualization. They have access to a limited set of features and resources provided by the web browser, such as user input events and graphics libraries, but are restricted from accessing resources on the user's computer or network. In recent years, the use of applets has declined in favor of other technologies such as JavaScript, HTML5, and CSS. However, applets are still supported by some web browsers and can be a useful tool in certain situations where other technologies may not be...

Vector in Java

-
  In Java, a vector is a resizable collection of objects, similar to an array, but with some additional functionality. A vector can grow or shrink dynamically, and can be accessed using an index just like an array. To use a vector in Java, you first need to import the java.util.Vector package. Then you can create a new vector object using the following syntax: java Copy code Vector<Object> vectorName = new Vector <Object>(); Here, Object can be replaced with any data type that you want to store in the vector. For example, if you want to store integers, you can use: java Copy code Vector<Integer> intVector = new Vector <Integer>(); To add elements to the vector, you can use the add() method: java Copy code intVector.add( 1 ); intVector.add( 2 ); intVector.add( 3 ); To access an element in the vector, you can use the get() method: java Copy code int element = intVector.get( 0 ); // returns the first element (1) You can also use other methods provided...
