Q)Modify the above application(MThreading.java) so as to have only one user defined thread class.
//MThreading2.java
class ThreadOne extends Thread{
	   public void run(){
		    Thread t=Thread.currentThread();//returns the currently running thread reference
			String name=t.getName();
		    if(name.equals("one")){
                for(int i=1;i<=20;i++){
		           System.out.println("Thread 1:"+i);
	            }//task1
            }
		    else{
	          for(int i=21;i<=40;i++){
		        System.out.println("Thread 2:"+i);
	          }//task2
           }
	}//body of the thread
}
class  MThreading2{
	public static void main(String[] args){
		ThreadOne t1=new ThreadOne();
		ThreadOne t2=new ThreadOne();
		t1.setName("one");
		t2.setName("two");
		t1.start();		
		t2.start();
	}
}
Q)Modify the first multithreaded application(MThreading.java) so as to use Runnable interface.
=>When a user defined Java class is inheriting from another Java class and for this
user defined class if we want to apply multithreading, that class can't extend
java.lang.Thread class. In this scenario, java.lang.Runnable interface is used
to implement multithreading.
Note:- Whenever user defined class is implementing Runnable interface,
we have to create the thread objects by instantiating java.lang.Thread class. 
To the Thread class constructor we have to supply Runnable object as argument.
Note:- Runnable interface object means, object of the user defined class that implements
Runnable interface.
//MThreading3.java
class ThreadOne implements Runnable{
	public void run(){
        for(int i=1;i<=20;i++){
		   System.out.println("Thread 1:"+i);
	   }
	}
}
class ThreadTwo implements Runnable{
	public void run(){
        for(int i=21;i<=40;i++){
		   System.out.println("Thread 2:"+i);
	   }
	}
}
class  MThreading3{
	public static void main(String[] args) {
		Thread t1=new Thread(new ThreadOne());
		Thread t2=new Thread(new ThreadTwo());
		t1.start();		
		t2.start();
	}
}
