Code

If you run the below code, public static void main method, the code execution will result in a deadlock.

public class Singleton {
    public static final int TIMEOUT = getValue();

    private static int getValue() {
        return 10;
    }

    private static final Singleton INSTANCE = new Singleton();

    private Singleton() {
        synchronized (this) {
            Thread thread = Thread.currentThread();
            while (thread.isAlive()) {
                try {
                    wait(500);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }
    }

    public static Singleton instance() {
        return INSTANCE;
    }

    @Override
    public String toString() {
        return "Singleton{}";
    }
}

class SomeClass {
    public static void main(String[] args) {
        new Thread(() -> System.out.println("the timeout value is " + Singleton.TIMEOUT)).start();

        new Thread(() -> System.out.println("instance received " + Singleton.instance())).start();
    }
}
