   I was wondering whether any optimizations are automatically done by   
   the compiler or VM in Java in classes where methods are defined as   
   synchronized. I'm working with a library where a typical function is   
   defined so,   
      
   class Foo   
   {   
   private int a = 0;   
   private int b = 0;   
   public synchronized doSomethingWithA( int var )   
   {   
       int tmp = some_function( var ); // heavy computation   
       a += tmp;   
   }   
   public synchronized doSomethingWithB( int var )   
   {   
       int tmp = some_function( var ); // heavy computation   
       b += tmp;   
   }   
   };   
      
   Can the compiler see that the first statement in the methods are local   
   and therefore not lock the object for that statement, and hold the   
   lock only for the actual addition part, so that it saves time?
