Introduction of Java : 

Java is an object oriented programming language. Java is also called high level language.

Java is a multiple platform and distributed programming language that is used to create Web Application, GOI Application, Console Application, Mobile Application Development, Game Application Development etc.

Java is free to access and can run on all platforms. The Java syntax is similar to C++, but is strictly an object-oriented programming language. 

Java can be used to create complete applications that may run on a single computer or be distributed among servers and clients in a network. 

Java is a programming language expressly designed for use in the distributed environment of the Internet. Java is used to create software and applications. At present, not only in computer but on Android phone, electronic devices etc.

History of Java : 

Java is a computer based programming language developed by Games gosling and their companion sun microsystems in 1991.

 James Gosling is said to be president of java, the only principle behind making java was "Wite once run anywhere". This means the language will be written once and will be used everywhere.

Importance of Java : 

The popular feature of Java is that the Java platform is independent which means that the Java programming language is not designed for any hardware or operating system. 

Any program created on Java will run on any system. Nowadays online banking, online shopping etc. All this is possible with Java. 

Google has named Android open source operating system development to mobile devices by connecting Java to Linux.

 Java is also very useful for creating websites and blogs. 

Java is based on C and C ++. The java file extension is .java which is generated in bitcoin format using the compiler. 

Java runs from virtual machines. The JVM is a virtual machine that provides a run time environment.

Uses of Java :

Java is used to build applications and platforms for a number of devices, including computers, laptops, gaming consoles, Blu-ray players, car navigation systems, medical monitoring devices, parking meters, lottery terminals and smartphones.

 It is also a key language for networking, particularly for data centers that store and transfer Web-based data.

Java is divided into three main parts. 

1. Java Micro Edition (J2ME)

 2.Java Standard Edition (J2SE) 

3.Java Enterprise Edition (J2EE)

Features of Java : 

1. Object-oriented : 

    Java is a clean object oriented programming language. It does not use procedures but it is a language based only on objects. Java follows the concept which simplifies the software development and maintenance work. 

2. Platform independent : 

    Java is platform independent language meaning it runs on any platform such as android, windows, linux and mac. 

3. Portable: 

    Java is a portable language because Java's source code is converted to byte code using the compiler. This byte code runs in any system. 

4. Secure: 

    Java is a secure language because the java program runs in the java run time environment.

5. Robust: 

    Robust means that a program built in Java works in different environments without any crash. Easily detect and fix any errors encountered in Java.

 Java runs on 3 billion devices these days.
