Implementing Runnable Interface

    Runnableinterface declare the run() method that is required for implementing threads in a program. To do this, the following steps have to be followed:

o   Declare the class as implementing the Runnable interface.

o   Implement the run()method.

o   Create a thread by defining an object that is instantiated from this “Runnable” class as the target of the thread.

o   Call the thread’s start()method to run thread.

    Example:

Class A implements Runnable

{

public void run()

 {

for(int i=1;i<=3;i++)

System.out.println("Thread A executing");

 }

}

classThreadrun

{

public static void main(String args[])

 {

  A a1= new A();

  Thread t=new Thread(a1);

t.start();

 }

}

Output:

Thread A executing

Thread A executing

Thread A executing
