BASICS OF JAVA

Introduction Of Java Programming

• It is a high level programming language originally developed by Sun Microsystem which was initiated by James Gosling in 1995.
• It runs on variety of platforms, such as Windows, Mac OS and various versions of Unix & Linux.
• It is based on WORA (Write Once, Run Anywhere), means a java code can run on all platform that support java without need of recompilation.
• The Java applications are typically compiled to bytecode that can run on any Java Virtual Machine (JVM) regardless of the underlying computer architecture.
• The syntax of Java is similar to C and C++, but it has fewer low-level facilities than either of them.

History of Java Programming

• James Gosling, Mike Sheridan and Patrick Naughton initiated the Java language project in 1991.
• It was originally designed for interactive television, but unfortunately it was too advanced for digital cable television industry at that time.
• It was initially called OAK after an oak tree later the project was named GREEN and was finally named Java, from Java Coffee, the coffee from Indonesia.
• Duke is the Java Mascot.

Primary Goal of Java Programming

There were five primary goals in the creation of the Java Language, which are as follows :

• It must be simple, object-oriented and familiar.
• It must be robust and secure.
• It must be architecture-neutral and portable.
• It must execute with high performance.
• It must be interpreted, threaded and dynamic.
