Simple validation

[samkal]

Can someone please let me know how to write code for validating user input with existing data.For example if I have all user names stored in an array and user1 enters only user instead of user1, program should pop up error message.

If you use an ArrayList instead of an Array, you can use the contains() method:

contains(Object elem)
Returns true if this list contains the specified element.

Thanks! Now i need to read enumerations from another class ( which is part of jar file). If I import that file and what is the way to read data from that class? Please let me know

I don't understand the question (but maybe someone else does; I'm still a bit of a piker with Java).

Sounds like some school assignment, the OP hasn't found google yet. It is all very elementary Java language usage.
