help with this program??

[babynailah]

I need to create this with java but for some reasons it is not working out for me.All that needs to be placed in a textarea......HELP!!

The cell phone must contain an array to hold a list of contacts. Each contact has a name and number. Make the size of the array 5 and be sure to account for increasing the array size if more than 5 numbers are added.
You should be able to add a contact to the list.

I am assuming you'd have to create a Contact class that stores the name and number.


Do you specifically have to use an array because an ArrayList would be more appropriate?
If you have to use array then
you would need an integer to store the maxPossible size of the array
your addContact(Contact c) method should check to see if the length of the array would exceed the maxPossible if one item is added. If true then create a bigger array, copy all existing contacts into it, add the new array and set it as the current lists of contacts.

What do you mean by

All that needs to be placed in a textarea

?

thank you for the repy but would you happen to have a code that i could go by because words really dont apply to me as much as seeing the data.....and i mean when the data is shown it has to be shown in a textarea?

Now that I've done all this for you, could you please add a delete contact button and make it work?

Your problem is to simulate certain aspects of a cell phone. The following features are required for the first assignment.


The interface must be a GUI that resembles a cell phone.
The cell phone must contain an array to hold a list of contacts. Each contact has a name and number. Make the size of the array 5 and be sure to account for increasing the array size if more than 5 numbers are added.
You should be able to add a contact to the list.
The Cell phone should have a selection that allows you to view your telephone number.
Modify the phone contacts to be stored in a link list.
The contacts must be stored in alphabetical order
You must have an option to edit a contact.
You must have an option to delete a contact


That is what i should have to this point but i dont have none of that because i cant get it to work

[r035198x]

Did ever bother to look at the code I have given you?

[babynailah]

i did but it dont work with the code i already have
