Definition   The SUPERFICIAL SIGNATURE of a Java program fragment is the fragment with:

1. All literals (constants) replaced by their type in angular brackets.
   
2. All objects referenced by variables replaced by the type of the object in angular brackets.
   

    

   Example  

   int x = 5;   double y = 3.5;   double p = x * y;   IO.println (``The product is ``+ p);

    

   The superficial signature is....  

   int x = < int >;   double y = < double >;   double p = < int > * < double >;   IO.println (< String > + < double >);

    

   Example  

   Circle c = new Circle (10);   Square s = new Square (10.0);   double aa = (c.area () + s.area ()) / 2.0;

    

   The superficial signature is....  

   Circle c = new Circle (< int >);   Square s = new Square (< double >);   double aa = (< Circle > .area () +   < Square > .area ()) / < double >;
