You were completely and utterly incapable even of reading your courseware or listening to your teacher while he was teaching you yet expect us to give you private tutoring here in the form of a few messages?
And you were completely incapable of reading Sun's own website which lists some excellent tutorials yet expect us to provide you with some?

And you want us to drop whatever we're doing to help you out NOW!!!!!! ?

Seems you have very weird expectations, and are extremely rude as well.

Learn some manners, follow your classes and do your homework next time, use the internet, bookstores, and libraries to gather your own information instead of waiting for it to be handed to you in predigested chunks, and maybe you'll learn something.

Aside from the rant below, what exactly are the specifications of your assignment? Do you need to have a GUI, have a limit in what data structures you can use?

ahm sorry to disturb you but all i say is who is willing to help me . . . sorry my mistake. . .

ahm do you have an yahoo messenger??? what is GUI??? sorry but i have not enough knowledge about computer

ahm thanks . . . your right but i really really need a help a help with this matter Iam realy begging you

Okay, calm down. List out: your program description, anything you are not allowed to use, specific trouble you might be having, in an orderly and logical fashion. Then maybe some help can be offered.

A GUI (Graphical User Interface) is basically what you see all the time. You click somewhere and an event is triggered and your program reacts. I don't think a first year IT student would be required to design a GUI.
You do need to be more specific. Here's some key aspects:

Do you need to be able to store the phone numbers?

Is it a console application or a GUI?

You'll obviously need to store your data internally. Using a class would be a good idea:


It probably should be an internal class. Then in your outer class you'd have an array of Data:

Where n is some max limit of entries. If there is no max then a Vector can be used as it grows without restriction.

You would be able to then add and implement a search algorithm and that's that

If you need to store, the class Data can be written to a file with ease.

All the best! Power to the people.

how can i start a program??? how can i use switch control structure... i'm thinking of a program but i can't convert because of my limited knowledge in java syntax...

ahm sorry i dont want to do this but this is maybe the last thing in my mind... our professor told us to create a program using java. this are the description. . .the program is like a phonebook containing of adding,deleting,editing,searching of users. . .
