Installation of Java

What is java?

Java starts from Green team. Java members also known as Green Team, initiated a revolutionary task to develop a language for digital devices such as set top boxes, television etc.

For the Green team members, it was an advance concept at that time. But, it was suited for internet programming. Later, Java technology as in corporate by Netscape.

  • James Gosling, Mike Sheridan, and Patrick Naugthon initiated the Java language project in June 1991. The small team of Sun engineers called Green Team.
  • Originally designed for small, embedded systems in electronic appliances like set top boxes.
  • Firstly, it was called “Green talk” by James Gosling and file extension was .gt.
  • After that, it was called Oak and was developed as a part of the Green Project.
  • In 1995, Oak was renamed as “Java” because it was already a trademark by Oak technology.
  • Java originally developed by James Gosling at Sun Microsystems, which is now a subsidiary of Oracle Corporation and released in 1995.
  • Java programs are platform independent which means they can be run on any operating system with any type of processor as long as the Java interpreter is available on that system.
  • Java code that runs on one platform does not need to be recompiled to run on another platform, it’s called “write once, run anywhere” (WORA).
  • Java Virtual Machine (JVM) executes Java code, but is written in platform specific languages such as C/C++/ASM etc. JVM is not written in Java and hence cannot be platform independent and Java interpreter is actually a part of JVM.
