Java synchronized difference threading [duplicate]

Answer 1

From locking perspective both behave the same. The only difference can be is that there can any non-null object used for a synchroized block ie.

public myFunction (){
   synchronized (anyObject) { 
 }
}

Now this block can be synchronized based on this object.

Where as for the case where the synchronized keyword was used , its synchronization scope depends on the calling object.

Hope this has helped you. Enjoy Coding!!!
