2) Java Thread Example by implementing Runnable interface

- Thread t1 =new Thread(m1); // Using the constructor Thread(Runnable r)
- t1.start();

What is the purpose of threading?
A thread is also called a lightweight process. Threads provide a way to improve application performance through parallelism. Threads represent a software approach to improving performance of operating system by reducing the overhead thread is equivalent to a classical process.
