For this exercise, you are going to write your code in the FormFill class instead of the main method. The code is the same as if you were writing in the main method, but now you will be helping to write the class. It has a few instance variables that stores personal information that you often need to fill in various forms, such as online shopping forms. Read the method comments for more information.

As you implement these methods, notice that you have to store the result of concatenating multiple Strings or Strings and other primitive types. Concatenation produces a new String object and does not change any of the Strings being concatenated.

Pay close attention to where spaces should go in theString, too.

FormFillTester has already been filled out with some test code. Feel free to change the parameters to print your own information. If you don’t live in an apartment, just pass an empty String for the apartment number in setAddress.
Don’t put your real credit card information in your program!

When you run the program as written, it should output
