CST242 Project 7: Chapter 20

Generic Classes and Methods

---

• Create a new Java project named "project-7" from the instructions for one of the exercises at the conclusion of Chapter 20:
   
  • 20.4 (Generic Method selectionSort) Complete this assignment as written for a maximum of 9 out of 10 points ; a reminder that the compareTo method is required here (in place of relational operators ==, >, <, etc.) because the wrapper types Integer and Float both are classes
  • 20.5 (Overloaded Generic Method printArray) Complete this assignment as written for a maximum of 8 out of 10 points ; for this exercise keep all the original code from Fig. 20.3 in the textbook and simply include this additional method and functionality in the updated program; an IndexOutOfBoundsException (from the Java API library) is thrown if lowSubscript and highSubscript are not both between zero (0) and one less than the number of elements in the array, or if lowSubscript is greater to highSubscript (Note: there is no such thing as "InvalidSubscriptException" as specified for this exercise in the textbook)
  • 20.7 (Generic Method isEqualTo) Complete this assignment as written for a maximum of 9½ out of 10 points ; write this exercise as an interactive application with user input from a Scanner object for input; use methods of class String or class Character to test the user input before converting to the correct type; throw a InvalidTypeException (imported from the Java API library) if the input for the two objects do not evaluate to the same type
  • 20.8 (Generic Class Pair) Complete this assignment as written for a maximum of 10 out of 10 points ; class Pair should have two constructors, one with no parameters and one that takes parameters for the two instance variables; also include a toString method to return a String representation of a Pair object; use your own creativity to design a driver for this assignment but take note that applications which demonstatrate more complexity and originality will get the better grades (Hint: recall that the concept of "pairs" comes from class Map which uses "keys" and "values")

• Provide full documentation using the Javadoc standard and based upon the downloaded sample files for the unit

---

• Students may work on all projects in teams of two or three, and, if so, all students in the group must submit the same project to their own dropboxes in Brightspace.  In the text box's dropbox, as well as in the source code documentation (comments), state the name(s) of the classmate(s) with whom you worked.
   
• When all steps are finished, create a .ZIP archive (not a .RAR) of the entire project.  This completed assignment with a copy of all files from the NetBeans project submitted electronically via an attachment to a Brightspace dropbox is due to Prof. Struck by 11:59 p.m. on the date specified in the course outline.
