java - IndexOutOfBounds with array

Question

Each time I try to run this method

private void resetOdds() {
    mOdds[1] = 0.10;
    mOdds[2] = 0.25;
    mOdds[3] = 0.35;
    mOdds[4] = 0.30;
}

I get an IndexOutOfBounds error. I don't know why, as I supply enough items in the array to change:

private final double[]      mOdds           = { 0.10, 0.25, 0.30, 0.35 };

Does anyone know why I'm getting this error?

Answer 1

Your indexing is off by one; it should start at 0:

mOdds[0] = 0.10;
mOdds[1] = 0.25;
mOdds[2] = 0.35;
mOdds[3] = 0.30;
