Print odd and even numbers using thread

How to print odd and even numbers one by one using thread ?

In this tutorial we will see how to print odd and even numbers starting from a particular number till a particular number using Threads. Below is the logic that we would be using to accomplish this:

• If number%2==1 then Odd thread will print the number and increment it else will go in the wait state.
• If number%2==0 then Even thread will print the number and increment it else will go in the wait state.

class MyRunnable implements Runnable{
 
	public int PRINT_NUMBERS_UPTO=10;
	static int  currentNumber=1;
	int remainder;
	static Object obj=new Object();
 
	MyRunnable(int remainder){
		this.remainder=remainder;
	}
 
	@Override
	public void run() {
		while (currentNumber < PRINT_NUMBERS_UPTO) {
			synchronized (obj) {
				while (currentNumber % 2 != remainder) { // wait for numbers other than remainder
					try {
						obj.wait();
						Thread.sleep(3000); //some dummy process
					} catch (InterruptedException e) {
						e.printStackTrace();
					}
				}
				System.out.println(Thread.currentThread().getName() + " " + currentNumber);
				currentNumber++;
				obj.notifyAll();
			}
		}
	}
}

Call the above class from a main class:

public class Manager {
	public static void main(String[] args) { 
		Thread t1=new Thread(new MyRunnable(1),"Odd");
		Thread t2=new Thread(new MyRunnable(0),"Even");
		
		t1.start();
		t2.start(); 
	}
}
