Big Java & Java Concepts example project "triangle1"

You can use this project as follows:

 - invoke the main method of the driver class TriangleTester by right-clicking 
 on the class representation and selecting the main method.
 - interactively create Triangle objects of differing widths (eg. 3 & 15) 
 - call the toString method of each method
   
This project illustrates concepts covered in Big Java & Java Concepts, Chapter 7 
"Iteration".
  
 - to be able to program loops with the while, for, and do statements
 - to avoid infinite loops and off-by-one errors
 - to understand nested loops
