// Store this program in file program1.java. In the same directory, create
// another directory Geometry in which you store Point.java, Triangle.java.
// This forms the package Geometry.
// Note that you can't access x attribute of P directly by P.x 
// since the attribute x in class Point is declared as "double x". 
// So it is visible only with in the classes of 
// package Geometry. For example it is possible to directly access 
// attribute of a point in some method of Triangle.java.
//---------------------------------------------------------------------------
//Try out the following exercises :
//1. Replace the 2nd statement in the following program by 
//   "double x = P.x". Now try to compile the program. Give reason for the
//   compilation error.
//2. declare x as "public double x" in Point.java. Replace the 2nd statement
//   in the following program with "double d = P.x". 
//   Now try to comiple and run this program.
