Locking and synchronization between outer and inner class methods?

Question

My question is if I have some code like the following -:

public class OuterClass{
   public class InnerClass{
          public synchronized methodA(){ /* doe         


        

Answer 1

It will use the this of the immediately enclosing class so the inner class. You can use instead:

public void m() {
    synchronized(OuterClass.this) {
    }
 }
