creating threads through annomyous inner class
<p>I was developing the code of creating a thread but without extending the thread class or implementing the runnable interface , that is through anonymous inner classes ..</p>

<pre><code>public class Mythread3 {
    public static void main(String... a) {

        Thread th = new Thread() {

            public synchronized void run() {
                for (int i = 0; i &lt; 20; i++) {
                    try {
                        Thread.sleep(1000);

                        System.out.print(i + "\n" + "..");
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }

            }

        };

        th.start();
        Thread y = new Thread();
        y.start();

    }
}
</code></pre>

<p>Now please advise me can I create child threads also with the same approach..!! what I have tried is that...</p>

<pre><code>public class Mythread3 {
    public static void main(String... a) {

        Thread th = new Thread() {

            public synchronized void run() {
                for (int i = 0; i &lt; 20; i++) {
                    try {
                        Thread.sleep(1000);

                        System.out.print(i + "\n" + "..");
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }

            }

        };

        Thread th1 = new Thread() {

            public synchronized void run() {
                for (int i = 0; i &lt; 20; i++) {
                    try {
                        Thread.sleep(1000);

                        System.out.print(i + "\n" + "..");
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }

            }

        };
        th.start();
        try {
            th.join();
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        th1.start();

    }
}
</code></pre>

<p>But there are two run() methods in it, I think this not practical..please advise..!</p>
