In this program, two threads are created along with the "main" thread. The currentThread() method of the Thread class returns a reference to the currently executing thread and the getName( ) method returns the name of the thread. The sleep( ) method pauses execution of the current thread for 1000 milliseconds(1 second) and switches to the another threads to execute it. At the time of execution of the program, both threads are registered with the thread scheduler and the CPU scheduler executes them one by one.
class SampleThread extends Thread{
SampleThread(String s){
super(s);
start();
}
public void run(){
for(int i=0;i<5;i++){
System.out.println("Thread Name :"
+Thread.currentThread().getName());
try{
Thread.sleep(1000);
}catch(Exception e){}
}
}
}
public class MultiThread1{
public static void main(String args[]){
System.out.println("Thread Name:"
+Thread.currentThread().getName());
SampleThread m1=new SampleThread("My Thread 1");
SampleThread m2=new SampleThread("My Thread 2");
}
}
output of the program is
Thread Name:main
Thread Name :My Thread 1
Thread Name :My Thread 2
Thread Name :My Thread 1
Thread Name :My Thread 2
Thread Name :My Thread 1
Thread Name :My Thread 2
Thread Name :My Thread 1
Thread Name :My Thread 2
Thread Name :My Thread 1
Thread Name :My Thread 2
