HOW TO IMPLEMENT THREADS IN JAVA CODE

Inherting Thread Class

// ThreadDemo.java
class ThreadDemo
{
   public static void main (String [] args)
   {
      MyThread mt = new MyThread ();
      mt.start ();
      for (int i = 0; i < 50; i++)
           System.out.println ("i = " + i + ", i * i = " + i * i);
   }
}
class MyThread extends Thread
{
   public void run ()
   {
      for (int count = 1, row = 1; row < 20; row++, count++)
      {
           for (int i = 0; i < count; i++)
                System.out.print ('*');
           System.out.print ('\n');
      }
   }
}

Implementing Runnable Interface

Java

package com.myjava.threads;
 
class MyRunnableThread implements Runnable{
 
    public static int myCount = 0;
    public MyRunnableThread(){
         
    }
    public void run() {
        while(MyRunnableThread.myCount <= 10){
            try{
                System.out.println("Expl Thread: "+(++MyRunnableThread.myCount));
                Thread.sleep(100);
            } catch (InterruptedException iex) {
                System.out.println("Exception in thread: "+iex.getMessage());
            }
        }
    } 
}
public class RunMyThread {
    public static void main(String a[]){
        System.out.println("Starting Main Thread...");
        MyRunnableThread mrt = new MyRunnableThread();
        Thread t = new Thread(mrt);
        t.start();
        while(MyRunnableThread.myCount <= 10){
            try{
                System.out.println("Main Thread: "+(++MyRunnableThread.myCount));
                Thread.sleep(100);
            } catch (InterruptedException iex){
                System.out.println("Exception in main thread: "+iex.getMessage());
            }
        }
        System.out.println("End of Main Thread...");
    }
}

best luck
