Lunchcard

You will write a Java class to represent a lunchcard (much like your RU id).

• The first version of the constructor will initialize the instance data name to owner, passed to it as a paramter. It will initialize the number of meals to 0. The constructor is overloaded. The second version of the constructor will let the client pass in a number of meals, instead of initializing the number of meals to 0.
• swipe is also overloaded. It will remove one meal from the card, unless it it is given an integer number as a parameter, in which case it will remove that number of meals from the card. It returns the number of meals remaining.
• buy, also overloaded, will add meals to the card, either the number specified by the parameter, or, 25 meals if no number is specified.
• the toString method will return a string showing the name of the card's owner and the number of meals remaining on that card.

Write a driver program which tests all of these methods. The purpose of this program is just to test the methods in your class file. (You don't need to get any info from the user, just make up all the data in your driver program.) Make println statements to let you know what the program is doing.

A sample run will look like this:

Once you have your program working, show your lab to the Peer Instructor to be checked off.
