How can I pass a parameter to a Java Thread?

Question

Can anyone suggest to me how I can pass a parameter to a thread?

Also, how does it work for anonymous classes?

Answer 1

You require to relinquish the parameter in the constructor to the Runnable object:

public class MyRunnable implements Runnable {

   public MyRunnable(Object parameter) {

       // store parameter for later user

   }

   public void run() {

   }

}

and execute it thus:

Runnable r = new MyRunnable(param_value);

new Thread(r).start();
