java字符串将不会绘制

Question

差不多两天了，我还没弄明白。我很确定我现在失眠了，我只是想知道怎么做。我要绘制的字符串位于Square类的startName（）中。正在startNormalMode（）中的NormalMode类中调用该方法。晚上9点睡觉晚上11:30醒来，现在是凌晨3:05，我仍然无法入睡，因为这个问题。尽可能多的信息是感激的，我只是不想成为一个更好的程序员。没有什么比经验更好的了

                e.printStackTrace();

            }

}

我的NormalMode类：

package data.src;

public class NormalMode extends BasicGameState {

    private Square[][] square = new Square[4][4];
    private Square squareChecker;
    Graphics g;


    public NormalMode() {


                }

    @Override
    public void init(GameContainer arg0, StateBasedGame Game)throws SlickException {
        squareChecker = new Square();
                    for(int i = 0; i < square.length; i++){
                        for(int j = 0; j < square.length; j++){
                            square[i][j] = new Square();
                            square[i][j].createRandom();

                        }
            }
                    startNormalMode(arg0);
    }                



    @Override
    public void render(GameContainer container, StateBasedGame game, Graphics g)
            throws SlickException{

                square[0][0].squareDraw(100, 300, g);
                square[0][1].squareDraw(150, 300, g);
                square[0][2].squareDraw(200, 300, g);
                square[0][3].squareDraw(250, 300, g);

                square[1][0].squareDraw(100, 400, g);
                square[1][1].squareDraw(150, 400, g);
                square[1][2].squareDraw(200, 400, g);
                square[1][3].squareDraw(250, 400, g);

                square[2][0].squareDraw(100, 500, g);
                square[2][1].squareDraw(150, 500, g);
                square[2][2].squareDraw(200, 500, g);
                square[2][3].squareDraw(250, 500, g);

                square[3][0].squareDraw(100, 600, g);
                square[3][1].squareDraw(150, 600, g);
                square[3][2].squareDraw(200, 600, g);
                square[3][3].squareDraw(250, 600, g);


                    }

    @Override
    public void update(GameContainer container, StateBasedGame game, int delta)
            throws SlickException {

    }

    @Override
    public int getID() {
        return 3;
    }


public void startNormalMode(GameContainer container)throws SlickException{

        Graphics g1 = container.getGraphics();


        squareChecker.startGame(g1, container);

    }
}

注：我使用的是slick2D库，没有错误，字符串没有出现在屏幕上

根据原始帖子中的评论，只需检查游戏渲染图形的元素。第一个元素将被正在绘制的最后一个元素覆盖
