HashMap, two keys to one value.

Hi guys,

I'll get straight to it.

I need a 6x6 matrix where each row is designated a value from 0 to 5 and each column is designated the values from 0 to 5.
For each element of the matrix i need to assign a value, object or String.
I then need to access a any given element corresponding to a particular row and column. ie row 3 column 2.

Can I do this using a HashMap? I am very new to java and am still not full sure of the syntax.

How do I create such a matrix, add an element to the matrix?
Any help is much appriciated :) Thanks
