一般都是都在页面做弹出框，如果后台要做弹出框就可以用JOptionPane类，其中封装了很多的方法。

import javax.swing.JOptionPane;

showMessageDialog

JOptionPane.showMessageDialog(null, "SUCCESS!");

JOptionPane.showMessageDialog(null, "SUCCESS", "TITLE",JOptionPane.PLAIN_MESSAGE);

JOptionPane.showMessageDialog(null, "SUCCESS", "TITLE",JOptionPane.WARNING_MESSAGE);

JOptionPane.showMessageDialog(null, "ERROR" , "TITLE",JOptionPane.ERROR_MESSAGE);

showOptionDialog

int n = JOptionPane.showConfirmDialog(null, "DOWN OR NOT", "TITLE",JOptionPane.YES_NO_OPTION);//Y 0 N 1

Object[] options ={ "OH YES!", "NONO!" };

int m = JOptionPane.showOptionDialog(null, "DOWN OR NOT", "TITLE",JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE, null, options, options[0]);

showInoutDialog
Object[] obj2 ={ "RED", "YELLOW", "GREEN" };

String s = (String) JOptionPane.showInputDialog(null,"WHAT COLOR DO U LIKE?", "COLOR", JOptionPane.PLAIN_MESSAGE, new ImageIcon("icon.png"), obj2, "RED");
