Programming Reusability

 In the real world, an entire program is rarely written from scratch. It  is very likely that there are classes or functions that already exist.  The key to using these existing modules successfully depends on how  modular the classes or functions are written.   

Your mission is to take a section of one program  and replace a similar section of another program.    

Write a 300-word paper describing the following:

• 
  
• The process of identifying the classes or functions for replacement 
• How the two programs were selected
• The changes needed to make the final Java™ application program work correctly  
• The final Java™ application program
