Java Program on Block Synchronization

Program 1

// Outer resource method
package dataflair;

public class MyTable 
{
     void showTable(int n)
     {
         System.out.println("Data Flair Free Coruse");
         System.out.println("Wel come you all in Data Flair Free Coruse");
         synchronized(this)
         {    
           try
           {
               int i;
               for(i=1;i<=10;i++)
               { 
                   System.out.println(n*i);
                   Thread.sleep(1000);
               }
           }
           catch(InterruptedException e)
           {
               System.out.println(e); 
           }    
         }
         System.out.println("Hello MyTable"); 
         System.out.println("This is Block code"); 
     }
}

Program 2

// User defefine thread
package dataflair;

public class MyThread extends Thread
{
      private MyTable M;
      private int n;
      MyThread(MyTable M,int n)
      {
          this.M=M;
          this.n=n;
      }   
      public void run()
      {
          M.showTable(n);
      }
}

Program 3

package dataflair;

public class TestMain 
{
    public static void main(String[] args) throws InterruptedException
    {
        MyTable M=new MyTable();
        MyThread mt1=new MyThread(M, 5);
        MYThread1 mt2=new MYThread1(M, 8);
        mt1.start();
        mt2.start();
       
        mt1.join();
        mt2.join();
       
    }
    
}

Program 4

// User defefine thread
package dataflair;

public class MYThread1 extends Thread
{
      private MyTable M;
      private int n;
      MYThread1(MyTable M,int n)
      {
          this.M=M;
          this.n=n;
      }   
      public void run()
      {
          M.showTable(n);
      }
}
