First I need to create 2 classes. The first will contain an ID number and an array of 5 course titles. I also have to create a get and a set method for populating the ID. I also must create a method to get a course. It does this by taking an integer and returning the course to that position (0 through 4). Then I must create a set method that sets the value of one of the courses by taking two arguements a name and an integer and returning the name...
