Odd even number printing using thread

Question

Odd even number printing using thread.Create one thread class, two instance of the thread. One will print the odd number and the other will print the even number.

Answer 1

public class Number_Thread extends Thread {

String thread;
int limit;

public Number_Thread(String thread,int limit){
    this.thread=thread;
    this.limit=limit;
                                             }

Object lock=new Object();

public  void run()
{

    synchronized (lock) 
    {

          //------------------- "print even"--------------------//

      if(thread.equals("even"))
        {
            for (int i = 2; i <=limit; i+=2) 
            {

                 System.out.println(thread+" thread "+i);
            try {

            lock.wait(1000);
                 continue;

                }
              catch (InterruptedException e) {}
            }
            lock.notifyAll();
        }

         //------------------- "print odd"--------------------//

    if(thread.equals("odd"))
         {
         for (int i = 1; i <=limit; i+=2) 
             {
                System.out.println(thread+" thread  "+i);
            try {

                lock.wait(1000);
                    continue;
                }
            catch (InterruptedException e) {}
            }
            lock.notifyAll();
         }
      }
   }
}

     //------------------thread creater class------------------//
import java.util.Scanner;

public class Main_Thread {
private static Scanner s;
    public static void main(String[] args) throws InterruptedException {
        System.out.print("enter limit:\t ");
        s=new Scanner(System.in);
    int n=s.nextInt();
     s.close();
    Thread t1=new Number_Thread("even",n);
    Thread t2=new Number_Thread("odd",n);
    t2.start();
    Thread.sleep(100);
    t1.start();

 }

}

output for limit 5:

enter limit: 5

odd thread 1

even thread 2

odd thread 3

even thread 4

odd thread 5
