Java消息提示框JOptionPane的使用方法

• showMessageDialog只有一個肯定按鈕；

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, "錯誤提示框！", "哈哈",JOptionPane.ERROR_MESSAGE);

showOptionDialog有兩個選擇按鈕，有返回值是int型，0或者1，0表明是，1表明否java

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

Object[] options = {"不說","說"};
            JOptionPane.showOptionDialog(null,"你說話呀！！","標題",
                    JOptionPane.YES_NO_OPTION,JOptionPane.QUESTION_MESSAGE,null,options,options[0]);

showInputDialog有輸入列表，而且能夠將你選擇的那個對象返回；web

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

java運行框就會出現你剛纔所選擇的那個對象；
svg

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