About Question enthuware.ocpjp.v8.2.1547 :

So A is wrong because:

e.g.

Code: Select all

public synchronized void a() { b(); }

Code: Select all

public synchronized void b() {}

when a() is called, the thread already has the lock on the instance of the class, allowing it to enter b(), is that correct?

Correct.
