1、登录界面
把用户名和密码存储在user.txt文件里，在登录时，查询用户名和密码是否正确，如果正确，则进入到首页购票，如果用户名不存在，则进入注册界面。代码如下：
package 购票系统;
import java.awt.*;
import java.awt.event.AWTEventListener;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import javax.swing.*;
@SuppressWarnings("unused")
public class denglu {
JFrame frame=new JFrame("登录");
JLabel label1=new JLabel();
JLabel label2=new JLabel("欢迎来到火车票购票系统",JLabel.CENTER);
JLabel label3=new JLabel("用户登录",JLabel.CENTER);
JLabel label4=new JLabel("用户名",JLabel.CENTER);
JLabel label5=new JLabel("密码",JLabel.CENTER);
JLabel label6=new JLabel("按ESC键退出",JLabel.CENTER);
JTextField n1=new JTextField();
JPasswordField n2=new JPasswordField();
JButton button1=new JButton("登录");
JButton button2=new JButton("注册");
JButton button3=new JButton("管理员登录");
static String tel="null";
public denglu() {
label2.setFont(new Font("",Font.BOLD,40));
label3.setFont(new Font("",Font.BOLD,30));
label4.setFont(new Font("",Font.BOLD,20));
label5.setFont(new Font("",Font.BOLD,20));
label5.setFont(new Font("",Font.CENTER_BASELINE,20));
frame.setLayout(null);
Dimension screenSize=Toolkit.getDefaultToolkit().getScreenSize();
frame.setUndecorated(true);
frame.setSize(screenSize.width, screenSize.height);
ImageIcon i=new ImageIcon("./1.jpg");
i.getImage();
Image temp=i.getImage().getScaledInstance((int)screenSize.getWidth()/2,(int)screenSize.getHeight()-200, Image.SCALE_DEFAULT);
i=new ImageIcon(temp);
label1.setIcon(i);
label1.setBounds(20, 100, screenSize.width/2, screenSize.height-80);
label2.setBounds(0,50,screenSize.width/2, 100);
label3.setBounds(screenSize.width/2,250,screenSize.width/2, 100);
label4.setBounds(screenSize.width/2,350,screenSize.width/4, 30);
label6.setBounds(screenSize.width-100,0,100, 50);
n1.setBounds(screenSize.width/2+screenSize.width/6,350,300, 30);
label5.setBounds(screenSize.width/2,400,screenSize.width/4, 30);
n2.setBounds(screenSize.width/2+screenSize.width/6,400,300, 30);
button1.setBounds(screenSize.width/2+200,500,100, 30);
button2.setBounds(screenSize.width/2+350,500,100, 30);
button3.setBounds(screenSize.width/2+260,550,150, 30);
frame.add(label1);
frame.add(label2);
frame.add(label3);
frame.add(label4);
frame.add(label5);
frame.add(label6);
frame.add(n1);
frame.add(n2);
frame.add(button1);
frame.add(button2);
frame.add(button3);
frame.setResizable(false);
frame.setLocationRelativeTo(null);
frame.setVisible(true);
Toolkit.getDefaultToolkit().addAWTEventListener((AWTEventListener) new AWTEventListener() {
public void eventDispatched(AWTEvent event) {
if (((KeyEvent) event).getID() == KeyEvent.KEY_PRESSED) {
switch(((KeyEvent)event).getKeyCode()) {
case KeyEvent.VK_ESCAPE: System.exit(0); break;
}
}
}
}, AWTEvent.KEY_EVENT_MASK);
button1.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
@SuppressWarnings("deprecation")
String sum=n1.getText()+" "+n2.getText();
boolean cot=false;
String s;
try {
@SuppressWarnings("resource")
BufferedReader r=new BufferedReader(new FileReader("./user.txt"));
while((s=r.readLine())!=null) {
if(s.equals(sum)) {
cot=true;
tel=n1.getText();
}
}
if(cot) {
try {
BufferedWriter w=new BufferedWriter(new FileWriter("./ex.txt",true));
String Tel=tel;
w.write(Tel);
w.flush();
w.close();
} catch (IOException e1) {
e1.printStackTrace();
}
new shouye();
frame.dispose();
}else {
JOptionPane.showMessageDialog(null, "用户名或者密码错误，登录失败！");
}
} catch (Exception e1) {
e1.printStackTrace();
}
}
});
button3.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
// String sum=n1.getText()+" "+n2.getText();
@SuppressWarnings("deprecation")
String sum=n1.getText()+" "+n2.getText();
if(sum.equals("111 111")) {
new guanli();
frame.dispose();
}else {
JOptionPane.showMessageDialog(null, "用户名或者密码错误，登录失败！");
}
}
});
button2.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
new zhuce();
}
});
}
public String GetTel() {
return tel;
}
public static void main(String[] args) {
// TODO Auto-generated method stub
new denglu();
}
}
运行结果如下：
2、注册界面：如果登录时用户名不存在，则进入注册界面，注册时用户名用的是电话号码，注册时会首先在文件里查询用户名是否存在，如果用户名存在，则无法注册，否则输入用户名和密码可以显示注册成功，之后可以返回登录，代码如下：
package 购票系统;
import java.awt.*;
import java.awt.event.AWTEventListener;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import javax.swing.*;
@SuppressWarnings("unused")
public class zhuce {
JFrame fm=new JFrame("用户注册");
JLabel label1=new JLabel("用户名",JLabel.CENTER);
JLabel label2=new JLabel("密码",JLabel.CENTER);
JTextField n1=new JTextField();
JTextField n2=new JTextField();
JButton button1=new JButton("确定");
JButton button2=new JButton("返回");
public zhuce() {
fm.setLayout(null);
label1.setBounds(0,20,50, 40);
n1.setBounds(80,30,150, 30);
label2.setBounds(0,70,50, 40);
n2.setBounds(80,80,150, 30);
button1.setBounds(50,170,80, 30);
button2.setBounds(150,170,80, 30);
fm.add(button1);
fm.add(button2);
fm.add(label1);
fm.add(n1);
fm.add(label2);
fm.add(n2);
fm.setSize(300,300);
fm.setResizable(false);
fm.setLocationRelativeTo(null);
fm.setVisible(true);
button1.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
try {
BufferedWriter w=new BufferedWriter(new FileWriter("./user.txt",true));
String zhanghao=n1.getText();
String sum=n1.getText()+" "+n2.getText();
@SuppressWarnings("resource")
BufferedReader r=new BufferedReader(new FileReader("./user.txt"));
boolean cot=true;
String s;
while((s=r.readLine())!=null) {
if(sum.equals(s)) {
cot=false;
}
}
if(cot && zhanghao.length()==11) {
w.write(sum);
w.newLine();
w.flush();
w.close();
JOptionPane.showMessageDialog(null, "注册成功！");
try {
BufferedWriter bw=new BufferedWriter(new FileWriter("./information.txt",true));
String te="null null null "+sum;
bw.write(te);
bw.newLine();
bw.flush();
bw.close();
} catch (IOException e2) {
e2.printStackTrace();
}
}else {
JOptionPane.showMessageDialog(null, "账号已经存在");
}
} catch (IOException e1) {
e1.printStackTrace();
}
}
});
button2.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
new denglu();
fm.dispose();
}
});
}
}运行结果如下：
3、管理员登录，管理员的账号和密码设定为111和111，输入正确的账号和密码后登录到管理员界面，在管理员界面，可以对车票进行增加，修改和删除。代码如下：
package 购票系统;
