JOptionPane对话框错误

Question

我收到了一条错误消息：

The method showMessageDialog(Component, Object, String, int, Icon) in the type 
   JOptionPane is not applicable for the arguments (JFrame, String, String, int, int, ImageIcon, String) 

当我在JOptionPane.showMessageDialog上空盘旋时。我学习了java教程，不知道问题出在哪里。有什么想法吗？

Java教程：http://docs.oracle.com/javase/tutorial/uiswing/components/dialog.html#button

String option = "Restart";
JFrame frame = new JFrame();
ImageIcon ic = new ImageIcon("hangmanIcon.png");
JOptionPane.showMessageDialog(frame,
        "He's dead, game over. The word was " + wordList[level],
        "You Lost",
        JOptionPane.OK_OPTION,
        JOptionPane.INFORMATION_MESSAGE,
        ic,
        option);

Java用于JOptionPane将告诉您哪些方法签名是可用的/允许的，而该方法签名不是一个方法签名。您可能想用这个来代替：

public static void showMessageDialog(Component parentComponent,
                 Object message,
                 String title,
                 int messageType,
                 Icon icon)
                          throws HeadlessException

也许您想要使用的不是showMessageDialog，而是允许更多参数的showOptionDialog。

String[] options = {"Restart", "Exit"};
String option = options[0];
JFrame frame = new JFrame();
ImageIcon ic = new ImageIcon("hangmanIcon.png");
JOptionPane.showMessageDialog(frame,
        "He's dead, game over. The word was " + wordList[level],
        "You Lost",
        JOptionPane.OK_OPTION,
        JOptionPane.INFORMATION_MESSAGE,
        ic,
        options,
        option);
