i am really appreciate any help from you guys..
I am blind in Collections .... I would like to use collections in my project ?
Initially registration form ...
I get value from registration form. and form values will be stored in database ..
here can i use Collections ? which one i will use ?
you can use treemap which stores its elements in a tree and orders its elements based on their values.so it wil be easy to store and retreive the values.
thanks for your reply ...
1) what is the use of collections here ?
2)what it does ?
3)What is the benefit by using TreeMap in this area ?
4)why i use TreeMap not any other thing ?
1) We won't do your homework
2) We won't do your homework
3) We won't do your homework
4) Send me $50, 000, and I'll do your homework :P
How did you decided that you'd like to use collections in your project when you don't know what they are?

probably a line in his homework assignment "you have to use Collections" or something like that...
AFAIK TreeMap is not a Collection.
1/2) A collection represents a group of objects (quoting from the API)
3) TreeMap is a tree-based map that allow sorting and easy retrieval of matches.
4) I'd rather use a simpler Map, as you are going to store a database. A Map basically allows you to retrieve a value from a key.
Is a requirement that you use a Collection to do your homework ?

TreeMap may not implement java.util.Collection, but it's still part of the collections API
