Modify your first program so that instead of reading in your personal information, it reads in a check and a deposit.  Create two separate classes for these, one called Check and the other called Deposit.  For now, do not have them inherit from a super class.  We will do that later.

The try and catch block with the declaration for the BufferedReader will now have to go into the main method.  The example below shows how to do this.  Also the readCheck and readDeposit methods will have to have the BufferedReader as a parameter.  Instead of having those methods catch the exception, you can throw the exception back to the main class and catch it there.

Store data for the check and the deposit in a file called checkFile.txt.  You may either create data of your own or use the data listed below.  If you use the data listed below, you have to make sure that your program reads the data in the order that it is listed in the file.  Otherwise you might read the wrong line into a field and get an error.

For now, we will treat dates as Strings in the format mm/dd/yyyy.  That is two digits for the month, two digits for the day and four digits for the year all separated by forward slashes.  If you want to handle the date in a different way, make sure that you include complete comments documenting what you have done.

Hand in a printout of your program and a disk with the .java, .class and .txt files.  Make sure the disk is labeled with your name and class.  I have extra labels if you need one.
