Question

I am creating one Testing Tool which is test the performance of the Web-Services. Now i want to test performance of my tool when 100 user hit this web service.
In Current, I create one thread which heat and show me request-response details in log. But i need to create 100 threads which work parallel and show me request-response of 100 threads.
My question is how to create 100 parallel thread's. Here i try to create 100 thread parallel but when i run this program it will not call run() method.

Here is my code.

public class Main implements Runnable
{
int counter= 0;
 public static void main(String args[]) throws Throwable  
 {      
  Thread t[]=new Thread[100];
  for (int j=0; j<100;j++)
  {
      t[j]=new Thread();
      t[j].start();       
  }          
 }
 public void run()
 {
  try {

        System.out.println("thread "
           +Thread.currentThread().getName()+" step "+counter++);

  } 
  catch (Throwable t) { 
      t.printStackTrace();
   }
 }
}

Give me some hint or reference. I don’t understand where i wrong.
Thanks in Advance.

You are not instantiating your thread class – which happens to be Main.

Your class should be like:

public class Main extends Thread {
    int counter= 0;
    public static void main(String args[]) throws Throwable {      
        Main t[] = new Main[100];
        for (int j=0; j<100;j++) {
            t[j] = new Main();
            t[j].start();       
        }          
    }
    public void run() {
        try {
            System.out.println("thread " + Thread.currentThread().getName()+" step "+counter++);
        } 
        catch (Throwable t) { 
            t.printStackTrace();
        }
    }
}
