thread why not to sleep

Posted by christoph on March 31, 2001 at 10:37 PM

I wrote a program .It want t1 thread go to sleep,but as I run this program,the results show it just run as many times as t2 and t3,why this happen.the program like this below:import java.lang.*;
public class jth extends Thread {
public static void main(String []args) {
long j=0;
Thread t1 = new Thread(new Runner());
Thread t2 = new Thread(new Run1());
Thread t3 = new Thread(new Run2());
// while (true)
// { for(long i=0;i<100000000;i++);
System.out.println("This is main thread");
//t1.setPriority(3);
t1.start();
t2.start();
t3.start();
//int p = getPriority();
System.out.println("The t1 thread priority is "+t1.getPriority());
System.out.println("The t2 thread priority is "+t2.getPriority());
//System.out.println("The main thread priority is "+p);
//t1.stop();
try{
System.out.println("t1 sleeping begin"); // t.join();
t1.sleep(100);
// t2.sleep(100);
// t3.sleep(200);
System.out.println("t1 sleeping finish");
}
catch (InterruptedException e)
{ System.out.println("interrupted exception"); }
while (true)
{ j++;
System.out.println("main is running:"+j);
}
// t1.yield();

}
}

class Runner implements Runnable {
private int l=0;
public void run() {
//for (int i=0;i<5;i++)
while (true)
{ //for(long k=0;k<1000;k++);
l++;
System.out.println("This is '111' thread:::"+l); }
}
}

class Run1 implements Runnable {
int m=0;
public void run() {
while (true)
{ //for(long k=0;k<1000;k++);
m++;
System.out.println("This is '222' thread:::"+m); }
}
}

class Run2 implements Runnable {
private int n=0;
public void run() {
while (true)
{ //for(long k=0;k<1000;k++);
n++;
System.out.println("This is '333' thread:::"+n); }
}
}
