      You are having trouble with a Scanner, right?  A Scanner that
reads from System.in, right?  And you expect to solve this by
doing something different with ... System.out?

     Here's a diagram (it's schematic, conceptual, not literal):

	<======================
	  Input goes THIS way
	Your problem is with THIS

	                          ======================>
	                           Output goes THAT way
	                        Your problem isn't with THAT
