What is the issue with this Producer Consumer Problem. Can you fix it.

public class ProducerConsumerProb {

	public static void main(String[] args) {
		Container container = new Container();
		Turn turn = Turn.PRODUCER;
		Producer p = new Producer(container, turn);
		Consumer c = new Consumer(container, turn);
		Thread pro = new Thread(p);
		Thread con = new Thread(c);
		pro.start();
		con.start();
	}

	public static class Producer implements Runnable{
		Container container;
		Turn turn;
		public Producer(Container integer,Turn turn) {
			this.container = integer;
			this.turn = turn;
		}
		
		@Override
		public void run() {
			for(int i=0;i<10;i++){
				Turn temp = null;
				while(true){
					synchronized (turn) {
						temp = turn;
					}
					if(temp == Turn.PRODUCER){
						break;
					}
				}
				synchronized (turn) {					
					container.setI(i);
					turn = Turn.CONSUMER;
				}
			}
		}
	}
	
	public static class Consumer implements Runnable{
		Container container;
		Turn turn;
		public Consumer(Container integer,Turn turn) {
			this.container = integer;
			this.turn = turn;
		}
		
		@Override
		public void run() {
			for(int i=0;i<10;i++){
				Turn temp = null;
				while(true){
					synchronized (turn) {
						temp = turn;
					}
					if(temp == Turn.CONSUMER){
						break;
					}
				}
				synchronized (turn) {					
					System.out.println(container.getI());
					turn  = Turn.PRODUCER;
				}
			}
		}
		
	}
	
	public static class Container{
		Integer i = new Integer(0);
		

		public int getI() {
			return i;
		}

		public void setI(int i) {
			this.i = i;
		}
				
	}
	
	enum Turn{
		PRODUCER,CONSUMER;
	}
}
