Java消息提示框JOptionPane的使用方法

• showMessageDialog只有一个确定按钮；

JOptionPane.showMessageDialog(null, "普通提示框！", "哈哈",JOptionPane.INFORMATION_MESSAGE);

JOptionPane.showMessageDialog(null, "警告提示框！", "哈哈",JOptionPane.WARNING_MESSAGE);

JOptionPane.showMessageDialog(null, "错误提示框！", "哈哈",JOptionPane.ERROR_MESSAGE);

showOptionDialog有两个选择按钮，有返回值是int型，0或者1，0代表是，1代表否

JOptionPane.showConfirmDialog(null,"yes or no","标题",JOptionPane.YES_NO_OPTION);

Object[] options = {"不说","说"};
            JOptionPane.showOptionDialog(null,"你说话呀！！","标题",
                    JOptionPane.YES_NO_OPTION,JOptionPane.QUESTION_MESSAGE,null,options,options[0]);

showInputDialog有输入列表，并且可以将你选择的那个对象返回；

Object[] objects = {"甲", "乙", "丙"};
        String s = (String) JOptionPane.showInputDialog(null, "请选择你的身份\n", "身份",
                JOptionPane.PLAIN_MESSAGE, new ImageIcon("icon.png"), objects, "足球");
        System.out.println(s);

java运行框就会出现你刚才所选择的那个对象；

String title = JOptionPane.showInputDialog(null, "请输入：\n", "title", JOptionPane.PLAIN_MESSAGE);
        System.out.println(title);
