Multithreading Programs

 ThreadD class:-

class ThreadD extends Thread{

 public void run(){

   System.out.println("run()");

  }

 public static void main(String[] args){

   

   ThreadD t = new ThreadD();

   t.start();

  }

}

ThreadInterface:- 

class Demo{

void show(){

  System.out.println("show()");

 }

}

interface I1{

 void disp();

}

class ThreadInter extends Demo implements Runnable,I1{

 public void run(){

  

   System.out.println("run()");

  }

 public void disp(){

  

   System.out.println("disp()");

  }

 public static void main(String[] args){

   

   ThreadInter obj = new ThreadInter();

   Thread t = new Thread(obj);

   t.start();

    obj.show();

    obj.disp();

 }

}

ThreadFun :-

 class ThreadFun extends Thread{

   

  public void run(){

   //System.out.println(getPriority()+"   "+isAlive());

 for(int i=0;i<5;i++){

    System.out.println(getName());

    try{ 

   Thread.sleep(1000);

}

   catch(Exception e){

    System.out.println(e);

   }   

}

 

 }

  public static void main(String[] args){

   

   System.out.println(Thread.currentThread().getPriority());

   

   ThreadFun t = new ThreadFun();

   t.setName("java");

   t.start();

   t.setPriority(10);

   ThreadFun t1 = new ThreadFun();

   t1.start();

   

}

}
