I have never posted anything in here for java so if I don'tuse the code tags right I apologize...anyways I compiled an assignment in text pad and have a ton or errors and I was wanting to know if it is something minor or I am really that stupid...thanks
Here is what the assignment says:
Write an application (PetAdvice.java) that recommends a pet for a user based on the user’s lifestyle. Prompt the user to enter whether he or she lives in an apartment, house, or dormitory (1, 2, or 3… 4 to quit) and the average number or hours the user is home per week.
Additional hints/requirements:
1. Do not use the default values for the title bar caption – see example below.
2. For your icons, use the question for input, the information “I” for output, and the error for error message dialog boxes.
3. You are required to use IF statements and case statements at some point in the program. I combined some IF statements with my case statements to come up with the pet in the getPet() method.
4. You should allow decimals for the hours input.
5. Make sure you provide reasonableness checks when necessary.
6. If the user makes an invalid entry, allow them to re-enter their data (loop back). However, you don’t need to loop back to the beginning at the end of your program. Once your user clicks the last OK, you can terminate.
7. You will be required to use multiple methods for this application (like we were doing with our Chapter 4 in-class exercises). You don’t have to use my exact methods, but here is what I used: getHousing(), getHours(), getPet(), output(), and finish().
8. Termination: program your cancel buttons to terminate in addition to terminating when your user selects 4 on the first screen.
Print your recommendation based on the following table:
Residence Hours Home Recommendations
House 18 or more Pot-bellied pig
House 10 to <18 Dog
House Fewer than 10 Snake
Apartment 10 or more Cat
Apartment Fewer than 10 Hamster
Dormitory 6 or more Fish
Dormitory Fewer than 6 Ant farm
this is what I have so far and if the code tags dont come out right please let me know
