difference between synchronizing a static method a

Question

What is the difference between synchronizing a static method and a non static method in java?Can anybody please explain with an example. Also is there any difference in synchronizing a method and synchronizing a block of code?

Answer 1

Dude, just a hint. Not related to your question:

If any do*Stuff() methods does either

this.a= /*yet another*/ new Object();

or

this.b= /*yet another*/ new Object();

then you are screwed. Because the lock is inside the value, not inside the reference. See Java synchronized references
