What Is Java Language?
This section provides a quick introduction of Java language, a general purpose and procedural programming language that supports object model, multi-threading, and garbage collection.
Java is a general purpose programming language developed in 1995 by Sun Microsystems.
The Java language was originally created by James Gosling in 1991 while working on the Stealth Project.
Main features of Java language:
- Java is platform independent. Java programs written in Java can run on any operating system platform
through a Java Virtual Machine (JVM) for that platform.
- Java supports object-oriented programming. Java was built exclusively as an object oriented language, everything in Java
is an object except that primitive-type values.
- Java supports automatic garbage collection. The built-in garbage collector will automatically free objects
that are not references anymore.
- Java supports multithreading (concurrency) programming. Multiple threads of executions can be initiated
and synchronized in a single Java application. All threads in a single application share the same set of resources.
