Producer Consumer multithreading problem using Java....

Here is the code .....

       

public class ProducerConsumerProblem {

 public static void main(String[] args) {
        
  DataClass c=new DataClass();
  Producer p1 = new Producer(c, 1);
  Consumer c1 = new Consumer(c, 1);
  p1.start();
  c1.start();

 }
}

class DataClass {
 int data;
 boolean dataAvailable = false;

 public synchronized int get() throws InterruptedException {

  while (dataAvailable == false) {
   wait();
  }
  dataAvailable = false;
  notifyAll();
  return data;
 }

 public synchronized void setData(int content) throws InterruptedException {

  while (dataAvailable == true) {
   wait();
  }
  data = content;
  dataAvailable = true;
  notifyAll();
 }
}

class Producer extends Thread {
 private DataClass dataObject;
 private int number;

 public Producer(DataClass dataClassReference, int num) {
  dataObject = dataClassReference;
  number = num;
 }

 public void run() {
  for (int i = 0; i < 10; i++) {
   try {
    dataObject.setData(i);
   } catch (InterruptedException e1) {
    // TODO Auto-generated catch block
    e1.printStackTrace();
   }
   System.out.println("Producer #" + this.number + " put: " + i);
   try {
    sleep((int) (Math.random() * 100));
   } catch (InterruptedException e) {
   }
  }
 }
}

class Consumer extends Thread {
 private DataClass dataObject;
 private int number;

 public Consumer(DataClass dataClassReference, int num) {
  dataObject = dataClassReference;
  number = num;
 }

 public void run() {
  int value = 0;
  for (int i = 0; i < 10; i++) {
   try {
    value = dataObject.get();
   } catch (InterruptedException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }
   System.out.println("Consumer #" + this.number + " got: " + value);
  }
 }
}
