Java Program to show Thread Synchronization – Q28

January 14, 2009 Leave a comment Go to comments

Q28: Java Program to show that if three threads are of equal priority and they are not synchronized then more than one thread may be executing in single function which give wrong values. Output ([hello[dear[bhaskar]]]).

class Callme{
	void call(String msg){
		System.out.print("[" + msg);
		try{
			Thread.sleep(1000);
		}
		catch(InterruptedException e){
			System.out.println("Interrupted");
		}
		System.out.println("]");
	}
}

class Caller implements Runnable{
	String msg;
	Callme target;
	Thread t;
	public Caller(Callme targ, String s){
		target = targ;
		msg = s;
		t = new Thread(this);
		t.start();
	}
	public void run(){
		target.call(msg);
	}
}

class Synch{
	public static void main(String args[]){
		Callme target = new Callme();
		Caller ob1 = new Caller(target, "Hello");
		Caller ob2 = new Caller(target, "Dear");
		Caller ob3 = new Caller(target, "Manoj");
		try{
			ob1.t.join();
			ob2.t.join();
			ob3.t.join();
		}
		catch(InterruptedException e){
			System.out.println("Interrupted");
		}
	}
}

… from College notes (BCA/MCA assignments):
