multithreading in java

class Count implements Runnable
{
   Thread mythread ;
   Count()
   { 
      mythread = new Thread(this, "my runnable thread");
      System.out.println("my thread created" + mythread);
      mythread.start();
   }
   public void run()
   {
      try
      {
        for (int i=0 ;i<10;i++)
        {
          System.out.println("Printing the count " + i);
          Thread.sleep(1000);
        }
     }
     catch(InterruptedException e)
     {
        System.out.println("my thread interrupted");
     }
     System.out.println("mythread run is over" );
   }
}
class RunnableExample
{
    public static void main(String args[])
    {
       Count cnt = new Count();
       try
       {
          while(cnt.mythread.isAlive())
          {
            System.out.println("Main thread will be alive till the child thread is live"); 
            Thread.sleep(1500);
          }
       }
       catch(InterruptedException e)
       {
          System.out.println("Main thread interrupted");
       }
       System.out.println("Main thread run is over" );

threads java

// Copy and test
// They run simultaneously

public static void main(String[] args) {
  		// How to create a thread
        Thread thread = new Thread(new Runnable() {
            @Override
			// Loop running in thread
            public void run() {
                for (int i = 0; i < 20; i++) {
                    System.out.println("Printing plus " + i + " in a worker thread.");
                    try {
                        Thread.sleep(1000);
                    } catch(Exception e) {
                        e.printStackTrace();
                    }
                }
            }
        });
        thread.start();
  		// Loop running in main thread 
        for (int j = 0; j < 20 ; j++) {
            System.out.println("Printing plus " + j + " in a main thread.");
            try {
                Thread.sleep(900);
            } catch(Exception e) {
                e.printStackTrace();
            }
        }
        }

create thread java

class RunnableObject implements Runnable {
   private Thread t;
   private String threadName;
   
   RunnableObject( String name) {
      System.out.println("Creating " +  threadName );
      threadName = name;
      t = new Thread (this, threadName);
   }
   
   public void run() {
      System.out.println("Running " +  threadName );
   }
   
   public void start () {
      System.out.println("Starting " +  threadName );
      t.start ();
   }
}

public class TestThread {

   public static void main(String args[]) {
      RunnableObject R1 = new RunnableObject( "Thread-1");
      R1.start();
   }   
}

java thread

public static void main(String[] args {
   ...
   Thread t1= new Thread(...);
   t1.start();
   ...
}
