Java Programming

Im trying to write a chess game and I need it to check for check but i am stuck. Below is the code that i am trying at the moment, i'm only using bq(black queen) and moveUP (in the northern direction of the board) to check at the moment - there are bp (black pawns etc..) and of course moveDOWN, moveLEFT etc.

Any help would be appreciated.

public boolean isNotCheck(boolean b) {
        index = start - end;

            for (int i = 0; i < ChessModel.LENGTH - 1; i++) {
                if(model.getSquareAt(i).image == wk)
                {
                    for(int j = i; j < ChessModel.LENGTH -1; j += moveUP)
                    {
                        if(model.getSquareAt(j).image == bq)
                        {
                            JOptionPane.showMessageDialog(null, "Check");
                            return false;
                        }
                    }
                }
            }
        return true;
    }
