Nested synchronized keyword

Question

I have this code in Java:

    public void doSomeThing() {
        synchronized (this) {
            doSomeThingElse();
        }
    }
    public void doSome         


        

Answer 1

Lock already obtanied by the thread executing doSomething method, therefore this thread can execute doSomethingElse method.

You need two lock object to create a deadlock situation. In your case, there is only one, therefore it is impossible to create a deadlock.
