JRE: Java Runtime Envirnment

-

 JRE stands for "Java Runtime Environment." It is a software package that provides the necessary environment for executing Java applications on a computer or other device. The JRE includes the Java Virtual Machine (JVM), which is responsible for running Java code, as well as other libraries and components required for running Java applications.

The JRE is available for different platforms, such as Windows, Mac OS, and Linux, and is required for running many Java-based applications, including web applications, mobile applications, and desktop applications.

Developers can also use the JRE to test their Java applications before distributing them to end-users. Additionally, the JRE provides security features to help ensure that Java applications run safely on a user's computer or device.

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...
