Game of life

My board correctly identifies groups with less than 3 neighbors and kills them, but it does not seem to detect and give rise to cells with 3 neighbors.

Any thoughts?

If I have not provided sufficient information, let me know and I can insert more code, but I think that these are all relevant parts.

Thanks in advance for the advice you provided.

public boolean getCell(int row, int col) {
    boolean state = board[row][col];
    int neighbors = 0;
    for (int x = row-1; x <= row+1; x++) {
        for (int y = col-1; y <= col+1; y++) {
            // don't include this
            if ((x != row || y != col) && x != -1 && y != -1 
            && x != NROWSCOLS && y != NROWSCOLS) {
                if (board[x][y] == ALIVE){
                    neighbors ++;
                }
            }
        }
    }
    if (neighbors > 3 || neighbors < 2)
        state = DEAD;
    else if(neighbors == 3)
        state = ALIVE;
    return state;
}

The life cycle method is requested here.

/** Process one life cycle of the cellular automaton
 * 
 */
public void lifeCycle() {
    for (int x = 0; x < NROWSCOLS ; x++) {
        for (int y = 0; y < NROWSCOLS; y++) {
            getCell(x,y);
        }
    }

    generations ++;
}

I bound LifeGUI for reference, but this code is provided and not intended for me.
