我想做一個小小的彈出式遊戲。 我已經加入的故事和它的所有工作完全正常，直到我加入這一段代碼：JOptionPane.showOptionDialog不起作用
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
);
現在，這些選項會出現在該出現的每optiondialog。我該如何解決？
這是我的代碼
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" };
int action = JOptionPane.showOptionDialog(null, "What will you do?", "action",
JOptionPane.DEFAULT_OPTION, JOptionPane.QUESTION_MESSAGE,
null, options, options[0]);
switch (action)
{
case 0:
int Criticals = (int) (Math.random()*500);
Criticals++;
caitlyn.enemyhealth = (caitlyn.enemyhealth-Criticals);
JOptionPane.showMessageDialog(null, "Caitlyn now has" +" " + caitlyn.enemyhealth + "HP left");

JOptionPane.showMessageDialog(null, "Caitlyn is too injured by your strength to continue this battle. You are victorious!");
}
else
JOptionPane.showMessageDialog(null, "You are too injured to continue this battle. You are defeated.");

OOT但我的建議是總是通過父組件（窗口）作爲第一個參數'JOptionPane.showOptionDialog（）'。否則，您可能會在某些系統或多顯示器環境中遇到奇怪的問題 – 2013-02-21 14:01:32
是稍後添加到JComboBox或JCheckBox的那些選項???，爲了更快地發佈[SSCCE]（http://sscce.org/）可運行，可編譯 – mKorbel 2013-02-21 14:02:48
這是非常奇怪的，我用你的代碼，並添加了幾行來給你的應用程序類似的行爲，它工作正常。也許正如第一條評論所述，您需要指定將用於對話框的窗口，或嘗試在顯示新消息對話框之前使選項數組無效。 – 2013-02-21 14:08:45
