(1) Write a program to enter employee data, including SSN (Social Security Number) and salary into an array with maximum # of 100. Allow to enter less than 100 employees. (2) The program should use two exception class, one called: SSNLengthException when SSN entered without 2 dashes and not 9 digits one called: SSNCharacterException when SSN entered has non digits (3) When an exception is thrown, tell user what is entered and why it is wrong, ask reenter again. (4) After all data has been entered, display the records for all employees in console statement, with an annotation stating whether the employees salary is above or below average. (5) Design the THM class derived from book sample class Person, then add all required private variables, constructors, getters (accessor), setters (mutator), and methods of override, and overload types. (6) The program source should be appropriately indented, points will be cut for unconventional, rude and messy codes. (7) The program begins with one O/P statement in GUI, to display the title, author, and ID (8) The program should be user friendly, informative, and display clear statements, points will be cut heavily if this specs not met.

i have this so far and i am having trouble adding a GUI statement. No clue where to start. (GUI based)
