Implementing threads in java

public class First {

public static void main(String[] args) {
// TODO Auto-generated method stub
Sec obj = new Sec();
Thread t = new Thread(obj);
t.start();
}

}

public class Sec extends Thread{

public void run(){

for(int i=0;i<10;i++){

System.out.println("The value of i is " +i);

}

}

}

output:-

The value of i is 0

The value of i is 1

The value of i is 2

The value of i is 3

The value of i is 4

The value of i is 5

The value of i is 6

The value of i is 7

The value of i is 8

The value of i is 9
