remove duplicates from an array

[Pradeep Chauhan]

Hi there,
I have an array, String []
I have to remove duplicates from this array. I can use a temp array.
Could anybody guide me as how will I do this?

my array is 2d, let's say String [i][2] and I have to remove all the duplicates for
String[i][0] and String[i][1].

Is this homework? Have you tried anything yet? If you've tried something and you're stuck, let us see what you've done and we'll help.
In addition, since this doesn't really pertain to the SCJP certification, I'm moving this to Java in General (Beginner).

I have to remove duplicates from this array.

Are the duplicates allowed in the first place? If not, a HashSet may be a more appropriate data structure. If you insist on using an array, consider an ArrayList collection.

No Duplicates are not allowed in first place. Actually first place is a key.
Had it been one-dimesional array, I would have used HashSet. I don't know for 2d array.
Could anybody help me as I'm not an experienced guy in java.

What Eugene is getting at is you can put the Strings in a HashSet (or any Set for that matter) and attempting to add a duplicate will have no effect since Sets do not allow duplication.
