Improved GUI Payroll Application 

 Filenames: GUIPayroll.java, Employee.java, Utility.java 

 Modify your GUIPayroll project to handle invalid user input in the (expected) numeric fields. Use a try/catch block when you try to get a primitive numeric representation of your String values from the TextFields. 

 If you detect invalid input, change the text color in your TextArea to red.
