Write a java program to print even and odd values in sequence using two threads with Synchronization, wait, notify and notifyAll.

package com.dashzin.Thread;
public class PrintEvenOdd {

        public static void main(String ... args){
        Printer print = new Printer();
        Thread t1 = new Thread(new TaskEvenOdd(print, 10,  false));
        Thread t2 = new Thread(new TaskEvenOdd(print, 10, true));
        t1.start();
        t2.start();
    }
        
}

class TaskEvenOdd implements Runnable {
    private int max;
    private Printer print;
    private boolean isEvenNumber;

    TaskEvenOdd(Printer print, int max, boolean isEvenNumber){
        this.print = print;
        this.max = max;
        this.isEvenNumber = isEvenNumber;
    }

    @Override
    public void run() {
        int number = isEvenNumber == true ? 2 : 1;
        while(number<= max){
            if(isEvenNumber){
                print.printEven(number);
            }   
            else {
                print.printOdd(number);
            }
            number+=2;
        }
        }
}

class Printer {
    boolean isOdd= false;
    synchronized void printEven(int number) {
        while(isOdd == false){
            try {
                wait();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
        System.out.println("Even No:"+number);
        isOdd = false;
        notifyAll();
    }
    synchronized void printOdd(int number) {
        while(isOdd == true){
            try {
                wait();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
        System.out.println("Odd No:"+number);
        isOdd = true;
        notifyAll();
    }
}

Output : 

Odd No:1
Even No:2
Odd No:3
Even No:4
Odd No:5
Even No:6
Odd No:7
Even No:8
Odd No:9
Even No:10
