How can parameters be passed to Java threads?

Passing Parameters to Java Threads

To pass parameters to a thread, you can use the constructor of the Runnable object to store the parameter for later use. The following code snippet demonstrates this:

<code class="java">public class MyRunnable implements Runnable {

   public MyRunnable(Object parameter) {
       // store parameter for later user
   }

   public void run() {
   }
}</code>

To invoke the thread with a specific parameter, you can use the following syntax:

<code class="java">Runnable r = new MyRunnable(param_value);
new Thread(r).start();</code>

Anonymous Classes

Anonymous classes can also be used to pass parameters to threads. The following code snippet shows how:

<code class="java">new Thread(new Runnable() {

   @Override
   public void run() {
       // code to be executed
   }

}).start();</code>

In this example, an anonymous class is created that implements the Runnable interface. The parameter can be passed to the thread in the constructor of the anonymous class.
