Hey everyone!. I need to get output like in screenshot pinned to this message.

How i can get it from this code? Code:

class MyThreads {
    public final static Object den = new Object();
    public final static Object ada = new Object();
    private static volatile boolean isLocked = true;

    public static int n;
    public static int m;

    public static Thread t1 = new Thread() {
        public void run() {
            synchronized (den) {
                for (int i = 0; i < 5; i++, n++)
                    System.out.println("Thread1 n = " + n);
                Thread.yield();
                synchronized (ada) {
                    ada.notifyAll();
                    try {
                        ada.wait();
                        ada.notifyAll();
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                    for (int i = 0; i < 5; i++, m++)
                        System.out.println("Thread1 m = " + m);
                    System.out.println("Thread1 success!");
                }
            }
        }
    };
    public static Thread t2 = new Thread() {
        public void run() {
            synchronized (ada) {
                try {
                    ada.wait();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                for (int i = 0; i < 5; i++, m++)
                    System.out.println("Thread2 m = " + m);
                Thread.yield();
                synchronized (den) {
                    try {
                        den.wait();
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                    for (int i = 0; i < 5; i++, n++)
                        System.out.println("Thread2 n = " + n);
                    System.out.println("Thread2 success!");
                }

            }
        }
    };

You can test code with this:

public static void main(String[] args) throws InterruptedException {
        Thread thread1 = new Thread(() -> MyThreads.t1.run());
        Thread thread2 = new Thread(() -> MyThreads.t2.run());

        thread1.start();
        thread2.start();
        thread1.join();
        thread2.join();
    }

Code working like that:
