I am curious about how to Java application to calculate how much federal and state tax you need to pay. The program should accomplish the following tasks: ask your name, yearly income, federal tax rate, and state tax rate, then calculate and display the amount of tax you need to pay. Your program must catch user input errors. As the examples given above, use a dialog window to enter program input instead of console-based commands.  After you are done, zip "compress" the java source file along with some screen shots of your output and submit.
