Java is machine independent language. As like other languages, Java didn’t interfere deeply with hardware i.e program written in java from any OS will run at any machine.

The Java language was used in several projects within Sun but did not get very much commercial attention until it was paired with HotJava. HotJava was written in 1994 in a matter of months, both as a vehicle for downloading and running applets and also as an example of the sort of complex application that can be written in Java.

• Object Oriented:
  Java is an Object Oriented Language. Java can be easily extended since it is based on the Object model.
• Platform independent and Portable:
  Unlike many other programming languages including C and C++, when Java is compiled, it is not compiled into platform specific machine, It compiled into platform-independent byte code. This byte code is distributed over the web and interpreted by virtual Machine (JVM) on whichever platform it is being run. Java is Portable :).

• Simple and Easy to Learn:
  Java is designed to be easy to learn. If you understand the basic concept of OOP (Object Oriented Language), Java would be easy to master.
• Secure:
  With Java’s secure feature, it enables to develop virus-free, tamper-free systems. Authentication techniques are based on public-key encryption.
• Robust:
  Java makes an effort to eliminate error prone situations by emphasizing mainly on compile time error checking and runtime checking.
• Multi threaded:
  It is possible to write programs that can do many tasks simultaneously in Java. This design feature allows developers to construct smoothly running interactive applications.
• Interpreted:
  Java byte code is translated on the fly to native machine instructions and is not stored anywhere. The development process is more rapid and analytical since the linking is an incremental and lightweight process.
• High Performance and Dynamic:
  With the use of Just-In-Time compilers, Java enables high performance. Java is designed for the distributed environment of the internet. Java is considered to be more dynamic than C or C++ since it is designed to adapt to an evolving environment.

Getting Started with Java:

In order to write Java programs, you will, of course, need a Java development environment.It is also known as JDK. You can get the JDK (Java Development Kit) from CD’s available in the market or can download directly from Java official website according to your system requirements. Bellow are the necessary software to program in Java.
