      Illegal Forward Reference JLS Third Edition 8.3.2.3Naseem[ June 16, 2006: Message edited by: Naseem Khan ]

   
   

   
   
      Hi Ragu. This is very tricky question. The codeon line 2 is not right becuae it have the illegalforward references.

   
   

   
   
      here line 2 is allowed cos...here y takes the default value 0...whereas in line 1 variable y is on RHS..so it is bound to give a compilation error
