retrieving value from multi dimensional array by it's index in java

I have an array like this:

0  1  2
3  4  5
6  7  8

these numbers are indices of this array

this array has been initialized with:

1,1  3,1  5,1
1,3  3,3  5,3
1,5  3,5  5,5

which these numbers are the coordinate of the grid(the value inside my array). so my question is that, what should i do if i want to retrieve the value of one cell by it's index, for example if i call a method like getValue(5); the result would be 5,3. i know how to get the value in multi dimentional array but i don't know how to get taht with it's index.

Thank you

yourArray[5] gives a one dimensional array containing 5 and 3.

Edit: To address your comment.

function customIndex(int i) {
    return myArray[Math.floor(i/3)][i%3];
}
