Java is a popular programming language released in 1995. It is object-oriented, platform independent, and allows programs to run on many systems. Java programs can be developed for desktop applications, mobile apps, games, and enterprise software using powerful tools like Eclipse and NetBeans. There are three key Java platforms: Java SE for standard edition, Java EE for enterprise applications, and Java ME for micro devices. Java is widely used today for web applications, servers, and more due to its advantages of being easy to use, secure, and reliable.

2. What is Java technology and why
do I need it?
• Java is a programming language and computing
platform first released by Sun Microsystems in
1995.
• It is an object-oriented. An object can take
advantage of being part of a class of objects and
inherit code that is common to the class.
• It is fast, secure, and reliable. From laptops to
datacenters, game consoles to scientific
supercomputers, cell phones to the Internet, Java is
everywhere.

3. Advantages of Java
• Java is easy to learn. It was designed to be easy to
use and is therefore easy to write, compile, debug,
and learn than other programming languages.
• It is platform-independent. One of the most
significant advantages of Java is its ability to move
easily from one computer system to another.
• The ability to run the same program on many
different systems is crucial to World Wide Web
software.
• It has powerful development tools like Eclipse SDK
