3. Introduction:
Java is a general-purpose, class-based, object-oriented
programming language designed for having lesser
dependencies. It is a computing platform for application
Java is fast, secure, and reliable, therefore. It is widely used
developing Java applications in laptops, data centers, game
scientific supercomputers, cell phones, etc.
Java Platform is a collection of programs that help
programmers to develop and run Java programming
efficiently. It includes an execution engine, a compiler, and a
libraries in it. It is a set of computer software and
Gosling developed the Java platform at Sun Microsystems,
Oracle Corporation later acquired it.

4. History of Java:-
The history of Java is very interesting. Java was originally designed for interactive television, but it was too advanced
technology for the digital cable television industry at the time. The history of Java starts with the Green Team. Java team
members (also known as Green Team), initiated this project to develop a language for digital devices such as set-top boxes,
televisions, etc. However, it was best suited for internet programming. Later, Java technology was incorporated by Netscape.
The principles for creating Java programming were "Simple, Robust, Portable, Platform-independent, Secured, High
Performance, Multithreaded, Architecture Neutral, Object-Oriented, Interpreted, and Dynamic". Java was developed by James
Gosling, who is known as the father of Java, in 1995. James Gosling and his team members started the project in the early
'90s.
Currently, Java is used in internet programming, mobile devices, games, e-business solutions, etc. Following are given significant
points that describe the history java.
1) James Gosling, Mike Sheridan, and Patrick Naughton initiated the Java language project in June 1991. The small team of sun
engineers called Green Team.
2) Initially it was designed for small, embedded systems in electronic appliances like set-top boxes.
3Firstly, it was called "Greentalk" by James Gosling, and the file extension was .
4) After that, it was called Oak and was developed as a part of the Green project.

5. Application Of Java:
3 Web-based Applications
it provides vast support for web
development through Servlet, JSP,
and Struts. It is the reason that Java is also
known as a server-side programming
language.

Mobile App Development
The most popular android app development
IDE Android app also uses Java for
developing android applications.

Desktop GUI Applications
Java provides AWT, JavaFx, and Swing for
developing the GUI based desktop
application. The tools contain the pre-
assembled components like list, menu,
button..
2
Game Development
Java is widely used by game development companies
because it has the support of the open-source most
powerful 3D engine. The engine provides unparalleled
capacity when it comes to the context of the designing
of 3D games.
