数独GUI Java

Question

我试图用java创建一个动态数独的gui，事情就是我似乎无法获得 如果有人可以帮助我或者建议更好的话，右侧面板中的文本字段 解决这个问题我会很高兴。问题是我只在最后一个面板中获取文本字段（在右边的按钮处）。在所有其他面板中，我没有得到任何文本字段，不知道为什么：P

class Sudoku extends JPanel{
private JTextField textfields[][];  
private JPanel panels[][];

public Sudoku(int height, int weight, int dimension){
    super();
    panels = new JPanel[dimension][dimension];
    textfields = new JTextField[dimension][dimension];

    setLayout(new GridLayout());
    setForeground(Color.black);
    setBackground(Color.white);
    for (int i = 0;i <= dimension-1;i++ ) {
        for (int j = 0;j <= dimension-1;j++ ) {
            textfields[i][j] = new JTextField(1);
            textfields[i][j].setBackground(Color.YELLOW);
        }
    }

    for (int i = 0;i <= weight;i++ ) {
        for (int j = 0;j <= weight;j++ ) {
            panels[i][j] = new JPanel(new GridLayout(weight, weight));
        }
    }
    setLayout(new GridLayout(weight,weight,10,10));
    setForeground(Color.BLACK);

    for (int i = 0;i <= height-1 ;i++ ) {
        for (int j = 0;j <= weight-1 ;j++ ) {
            for (int k = 0;k <= height-1 ;k++ ) {
                for (int l = 0;l <= weight-1 ;l++ ) {
                    textfields[l][k].setEditable(false);
                    panels[i][j].add(textfields[l][k]);
                }
            }
            add(panels[i][j]);
        }
    }
