trouble with program

[jimJohnson]

i am finishing a java program up and a little confused....I need a clear button and know that is with the action listener but already have an item listener and confused on how to put a second one with a deadline in a couple hours midnight to be exact

output should be
Initial screen:

Enter the average number of hours you are home per week
House Apartment dormitory

Select your type of housing to determine the best pet

Clear Fields Button

Screen with valid Input


Enter the average number of hours you are home per week
House Apartment dormitory

Select your type of housing to determine the best pet
According to your requirements I would recommend a ....

Clear Fields Button

Invalid screen
Enter the average number of hours you are home per week
House Apartment dormitory

Select your type of housing to determine the best pet
Enter a valid number of hours between 0 and 168
Clear Fields Button

Code:

I hope I explained that clear enough...if not I will be back at 830 to explain it better
