Java Thread Example by extending Thread class

package com.pkm;

import java.util.Date;

/**

public class ThreadTest extends Thread {
    public static void main(String[] args) throws Exception {
        System.out.println("Thread called at = " + (new Date()));
        new ThreadTest().start();
    }

    public void run() {
        try {
            sleep(10000L);
        }
        catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println("Thread executed at = " + (new Date()));
    }
}

Java Thread Example by implementing Runnable interface

package com.pkm;

import java.util.Date;

/**
 * Created by pritom on 31/10/2017.
 */
public class RunnableTest implements Runnable {
    public static void main(String[] args) throws Exception {
        System.out.println("Thread called at = " + (new Date()));
        new Thread(new RunnableTest()).start();
    }

    @Override
    public void run() {
        try {
            Thread.sleep(10000L);
        }
        catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println("Thread executed at = " + (new Date()));
    }
}

So we can use "Runnable" interface, it will help us inherit another class, because if we use "Thread" inheritance then we should loose one scope to inherit another class if we need.
