key - information - map

[james_dixon_2008]

Hi Developers, I have to write an application where i could link keys with information so that i could use key to get the linked information. Like student name could act as a key and their grades could be information. So if i enter student name i should get his grades. Its like a map class basically. I dont have to use map class, i have to write my own class. So could anyone shed some light like what all would be required to get myself started. I mean what all classes would i be needing and etc I need to get on with this asap. Any help would be greatly appreciated. cheers James
