java模拟用户登录代码 java模拟用户登录代码怎么写

IT技术登录

求JAVA实现用户登录界面代码？你要先学会截图哦,你发的看不清楚,重新写了一个你参考参考!
import java.awt.GridLayout;
import javax.swing.ButtonGroup;
import javax.swing.JButton;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JRadioButton;
import javax.swing.JTextField;
public class Day30A extends JFrame {
private static final long serialVersionUID = 1L;
private JLabel labelName,labelId,labelPass,labelMoney,labelSelect,labelCar;
private JComboBoxString jcb;
private JPanel jp1,jp2,jp3,jp4,jp5,jp6,jp7;
private ButtonGroup btg;
private JRadioButton jr1,jr2;
Day30A(){
this.setTitle("注册账户");
this.setLayout(new GridLayout(7,1));
this.setSize(300,280);
this.setLocationRelativeTo(null);
this.setDefaultCloseOperation(EXIT_ON_CLOSE);
init();
this.setVisible(true);
}
private void init() {
String str="卡片类型1,卡片类型2,卡片类型3,卡片类型4,卡片类型5";
jcb=new JComboBox(str.split(","));
labelId=new JLabel("账号: ");
labelName=new JLabel("姓名: ");
labelPass=new JLabel("密码: ");
labelMoney=new JLabel("开户金额:");
labelSelect=new JLabel("存款类型:");
labelCar=new JLabel("卡片类型:");
addFun1();
addFun2();
}
private void addFun2() {
this.add(jp1);
this.add(jp2);
this.add(jp3);
this.add(jp4);
this.add(jp5);
this.add(jp6);
this.add(jp7);
}
【java模拟用户登录代码 java模拟用户登录代码怎么写】 private void addFun1() {
jp1=new JPanel();
jp1.add(labelId);
jp1.add(new JTextField(15));
jp2=new JPanel();
jp2.add(labelName);
jp2.add(new JTextField(15));
jp3=new JPanel();
jp3.add(labelPass);
jp3.add(new JTextField(15));
jp4=new JPanel();
jp4.add(labelMoney);
jp4.add(new JTextField(13));
jp5=new JPanel();

btg=new ButtonGroup();
jr1=new JRadioButton("定期");
jr2=new JRadioButton("活期",true);
btg.add(jr1);
btg.add(jr2);
jp5.add(jr1);

jp6.add(jcb);
jp7=new JPanel();
jp7.add(new JButton("确定"));
jp7.add(new JButton("取消"));
}
public static void main(String[] args) {
new Day30A();
}
}
java编写一个程序模拟用户登录操作 ， 用户名和密码从键盘输入？import java.util.Scanner;
public class LoginTest {
/**
* @param args
*/
public static void main(String[] args) {
String loginName = "admin";
String passWord = "123456";
Scanner sc = new Scanner(System.in);
boolean isSuccess = false;
int index = 0;
while(!isSuccess){
System.out.println("请输入用户名:");
String name = sc.nextLine();//读取字符串型输入
System.out.println("请输入密码:");
String passW = sc.nextLine();
if(loginName.equals(name)passWord.equals(passW)){
System.out.println("户名密码正确java模拟用户登录代码，退出程序");
isSuccess = true;
}else{
if(++index=3){
System.out.println("用户名密码错误java模拟用户登录代码，程序即将退出");
return;
}else{
System.out.println("用户名密码错误 ， 请重新输入");
}
}
}
}
}
模拟一个简单的用户登陆程序，判断登录的用户名和密码是否正确，输出登录判断结果，用java怎么写？package test;\x0d\x0aimport java.util.Scanner;\x0d\x0apublic class TestLogin {\x0d\x0aprivate static final String USERNAME = "Tom";//此处定义用户名\x0d\x0aprivate static final String PASSWORD = "123";//定义密码\x0d\x0apublic static void main(String[] args) {\x0d\x0aScanner sc = new Scanner(System.in);\x0d\x0aSystem.out.print("请输入您的用户名:");\x0d\x0aString username_in = sc.next();\x0d\x0aSystem.out.print("请输入您的密码:");\x0d\x0aString password_in = sc.next();\x0d\x0aif(username_in.equals(USERNAME)password_in.equals(PASSWORD)){\x0d\x0aSystem.out.println("登录成功");\x0d\x0a}else{\x0d\x0aSystem.out.println("用户名或密码错误");\x0d\x0a}\x0d\x0a}\x0d\x0a} \x0d\x0a这是从控制台输入的最简单的方法 。
