Java is an all round programming language which is typically object-oriented and class-based. It was designed by James Gosling, developed by Sun microsystems and released officially on the 23rd of May, 1995. Java programming language is designed to have only a few implementation dependencies as possible because it was intended to be written once, and run on any platform.
Java makes concurrency to be available to software developers through the application programming interface (API) and the language. Also, it supports multiple threads of execution, by making each thread have its respective program counter and method-call stack, which then allow concurrent executions with other threads.
The preferred means of creating multithreaded Java applications is by implementing the runnable interface. An object of a class that implements this interface represents a task to perform. The code is public void run ().
