我正在尝试制作一个小弹出游戏。我已经添加了故事，一切都运行得很好，直到我添加了这段代码:

    Object[] choices = null;
    Object[] options = { "Caitlyn", "Warwick", "Teemo", "Olaf", "Ashe" };
      int select = JOptionPane.showOptionDialog(null, "Who do you want to fight against?", "Champion selection",
            JOptionPane.CLOSED_OPTION, JOptionPane.QUESTION_MESSAGE, null, options, action
            );

现在，这些选项出现在出现的每个选项对话框中。我该如何解决这个问题？

这是我的代码

Object[] choices = null;
    Object[] options = { "Caitlyn", "Warwick", "Teemo", "Olaf", "Ashe" };
      int select = JOptionPane.showOptionDialog(null, "Who do you want to fight against?", "Champion selection",
            JOptionPane.CLOSED_OPTION, JOptionPane.QUESTION_MESSAGE, null, options, action
            );

      switch (select)
        {
        case 0: 
            int cait = 0;
            cait++;
            JOptionPane.showMessageDialog(null, "You will be fighting against the following champion:" + " " + caitlyn.Champion + "  " + "\n She is level" + "  " + caitlyn.Level + " " + "\n And she is a " + caitlyn.Type + "-Champion");

            JOptionPane.showMessageDialog(null, "You have started with 2000HP, Caitlyn has 1700HP.");

            // health

            newchamp.health = 2000;
            caitlyn.enemyhealth = 1700;

            //begin

            Object[] choices1 = null;
            Object[] options1 = { "Criticals", "Pure Damage", "Heal 300 points", "Flee" };

你注意到这部分代码了吗

Object[] choices2 = null;
        Object[] options2 = { "Criticals", "Pure Damage", "Heal 300 points", "Flee" };
          int action1 = JOptionPane.showOptionDialog(null, "What will you do?", "action",
                JOptionPane.DEFAULT_OPTION, JOptionPane.QUESTION_MESSAGE,
                null, **options**, options[0]);

** 表示可能的问题。不应该是 options2 吗？ (还有一些其他地方也可能出现同样的错误)
