PROGRAMMING IN JAVA - LECTURE -53- CREATING THREAD- BCA- S3.

CREATING THREAD
• Threads are implemented in the form of objects.
• The run() and start() are two inbuilt methods which helps to thread implementation
• The run() method is the heart and soul of any thread – It makes up the entire body of a thread
• The run() method can be initiating with the help of start() method.
1. By extending Thread class
2. By implementing Runnable interface
By Extending Thread class
class Multi extends Thread // Extending thread class
{
public void run() // run() method declared
{
System.out.println("thread is running...");
}
public static void main(String args[])
{
Multi t1=new Multi(); //object initiated
t1.start(); // run() method called through start()
}
}
Output: thread is running…
2. By implementing Runnable interface
Define a class that implements Runnable interface.
The Runnable interface has only one method, run(), that is to be defined in the method with the code to be executed by the thread.
2. By implementing Runnable interface
class Multi3 implements Runnable // Implementing Runnable interface
{
public void run()
{
System.out.println("thread is running...");
}
public static void main(String args[])
{
Multi3 m1=new Multi3(); // object initiated for class
Thread t1 =new Thread(m1); // object initiated for thread
t1.start();
}
}
Output: thread is running…
