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 need to pass 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 invoke it thus:

Runnable r = new MyRunnable(param_value); new Thread(r).start();
