Hi Jeet, I had googled and and found this..hope this will help you..
public class EvenRunnable implements Runnable {
private int number = 2;
private Object shared = null;
public EvenRunnable(Object object) {
shared = object;
}
public void run() {
while (number < 50) {
synchronized (shared) {
System.out.println("Even number = " + number);
number = number + 2;
try {
Thread.sleep(500); //only to view sequence of execution
shared.notify();
shared.wait();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
}
-----------------------------------
public class OddRunnable implements Runnable {
int oddNumber = 1;
private Object shared = null;
public OddRunnable(Object object) {
shared = object;
}
public void run() {
while (oddNumber < 50) {
synchronized (shared) {
System.out.println("Odd number = " + oddNumber);
oddNumber = oddNumber + 2;
try {
Thread.sleep(500); // only to view the sequence of execution
shared.notify();
shared.wait();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
}
--------------------------------
Now let us see the main class.
public class Main {
public Main(){
}
public static void main(String[] args) {
Object shared = new Object();
EvenRunnable evenRunnable = new EvenRunnable(shared);
OddRunnable oddRunnable = new OddRunnable(shared);
Thread evenThread = new Thread(evenRunnable, "evenThread");
Thread oddThread = new Thread(oddRunnable, "oddThread");
oddThread.start();
evenThread.start();
}
}
