对象引用未被识别[关闭]

Question

private GameController gc = new GameController();

private boolean timerstart = false;

private JButton bhit = new JButton("HIT");

private JButton bstand = new JButton("STAND");

private JButton bdd = new JButton("DOUBLE DOWN");

// private JButton bsplit = new JButton("SPLIT")

private JButton 5chips = new JButton("5");
private JButton 10chips = new JButton("10");
private JButton 25chips = new JButton("25");
private JButton 100chips = new JButton("100");

private JTextArea tap = new JTextArea(5,5);

private JTextArea tad = new JTextArea(5,5);

private JTextArea tac = new JTextArea("Welcome to BlackJack Simulator!",1,5);

private Container cp = getContentPane();
// create the panel containing panels
private JPanel mainchippanel = new JPanel(new FlowLayout());
// create the panel to contain the buttons
private JPanel chipandta = new JPanel(new BorderLayout());

private JPanel chipbuttons = new JPanel(new FlowLayout());

private JPanel playeroptions = new JPanel(new FlowLayout());

private JPanel optnsandta = new JPanel(new BorderLayout());

private JPanel mainoptnpanel = new JPanel(new FlowLayout());

private JPanel handdisplays = new JPanel(new BorderLayout());

private JPanel main1 = new JPanel(new BorderLayout());

private JPanel main2 = new JPanel(new BorderLayout());

我正在制作一个小程序，由于某种原因，只有从 gc 到 bdd 的代码被识别，就好像 5chips 及以后的 JButton 中的所有代码都不存在。

我知道这一点是因为类视图没有显示对 bdd 之后的代码的引用，并且对于每个对 bdd 之后的对象的引用，输出不断给出“预期”错误。

我不知道为什么会发生这种情况，因此我们将不胜感激。谢谢。

不能以带数字的变量名开头。 改为：

private JButton chips5 = new JButton("5");
private JButton chips10 = new JButton("10");
private JButton chips25 = new JButton("25");
private JButton chips100 = new JButton("100");
