JTextField是使用明文方式进行数据显示的,如果现在需要将回显的内容设置成其他字符,则可以使用JPasswordField类。
package com.beyole.util; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPasswordField; public class test18 { public static void main(String[] args) { JFrame frame = new JFrame("Crystal");// 实例化窗体对象 JPasswordField jPasswordField1 = new JPasswordField();// 定义密文框 JPasswordField jPasswordField2 = new JPasswordField();// 定义密文框 jPasswordField2.setEchoChar('#');// 设置回显字符为# JLabel label1 = new JLabel("默认的回显:"); JLabel label2 = new JLabel("设置的回显#:"); label1.setBounds(10, 10, 100, 20); label2.setBounds(10, 40, 100, 20); jPasswordField1.setBounds(110, 10, 80, 20); jPasswordField2.setBounds(110, 40, 50, 20); frame.setLayout(null); frame.add(label2); frame.add(label1); frame.add(jPasswordField2); frame.add(jPasswordField1); frame.setSize(300, 100); frame.setLocation(300, 200); frame.setVisible(true); } }
