Java History

-

 Java is a programming language that was first released in 1995 by Sun Microsystems. Here is a brief overview of its history:

  • 1991: James Gosling, Patrick Naughton, and others at Sun Microsystems started working on a project called "Green" to create a new programming language for consumer electronics and appliances.
  • 1993: The team released the first version of Java (then called "Oak") for use in set-top boxes and other devices.
  • 1995: Java 1.0 was released to the public. It quickly gained popularity because of its platform independence and its ability to run on any device with a Java Virtual Machine (JVM).
  • 1996: Sun Microsystems released the first version of Java Development Kit (JDK) 1.1, which included support for GUIs and improved performance.
  • 1998: Sun Microsystems released JDK 1.2, which introduced the Swing GUI toolkit and other significant updates.
  • 2000: JDK 1.3 was released, which included improvements to performance and stability.
  • 2002: JDK 1.4 was released, which included new features like the assert keyword, regular expression support, and improvements to the Java Virtual Machine.
  • 2004: Sun Microsystems released JDK 5.0 (also known as JDK 1.5), which included new features like generics, annotations, and autoboxing/unboxing.
  • 2006: Sun Microsystems released JDK 6, which included improvements to the Java Virtual Machine and the Java Standard Library.
  • 2010: Oracle Corporation acquired Sun Microsystems, becoming the owner of Java.
  • 2011: JDK 7 was released, which included improvements to performance, security, and language features.
  • 2014: JDK 8 was released, which introduced lambda expressions, a new date and time API, and other significant updates.
  • 2017: JDK 9 was released, which introduced modules as a new way of organizing and structuring code.
  • 2018: JDK 10 was released, which introduced local variable type inference and other language updates.
  • 2019: JDK 11 was released, which marked a shift to a new release schedule with a new version every six months.
  • 2021: JDK 16 was released, which included new features like records, pattern matching, and vector API.

Java has become one of the most popular programming languages in the world, with a large community of developers and a wide range of applications, from desktop and mobile apps to web development, enterprise software, and more.

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...
