Java Program to show implement Low & High priority Threads – Q27


Q27: Java Program to create clicker class which sets the priority of two threads (one is having high priority and one is having low priority) and whenever the thread is running it is increasing a counter. In the end print what is the value of the counter for both of the threads.

class clicker implements Runnable{
	int click=0;
	Thread t;
	private volatile boolean running=true;
	
	public clicker(int p){
		t = new Thread(this);
		t.setPriority(p);
	}
	
	public void run(){
		while(running){
			click++;
		}
	}
	
	public void stop(){
		running=false;
	}
	
	public void start(){
		t.start();
	}
}

class HiLoPri{

	public static void main(String args[]){
		Thread.currentThread().setPriority(Thread.MAX_PRIORITY);
		clicker hi = new clicker(Thread.NORM_PRIORITY+2);
		clicker lo = new clicker(Thread.NORM_PRIORITY-2);
		
		lo.start();
		hi.start();
		
		try{
			Thread.sleep(1000);
		}
		catch(InterruptedException e){
			System.out.println("Main thread interrupted.");
		}
		
		lo.stop();
		hi.stop();
		
		try{
			hi.t.join();
			lo.t.join();
		}
		catch(InterruptedException e){
			System.out.println("InterruptedException caught");
		}

		System.out.println("Low-Prioritythread value: " + lo.click);
		System.out.println("High-Prioritythread value: " + hi.click);
	}
}

… from College notes (BCA/MCA assignments):
