Java代码实现 User.java
```javapublic class User {
private String username;
private String password;
public User(String username, String password) {
this.username = username;
this.password = password;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
```
Recharge.java
```javapublic class Recharge {
private double amount;
public Recharge(double amount) {
this.amount = amount;
}
public double getAmount() {
return amount;
}
public void setAmount(double amount) {
this.amount = amount;
}
}
```
Withdraw.java
```javapublic class Withdraw {
private double amount;
public Withdraw(double amount) {
this.amount = amount;
}
public double getAmount() {
return amount;
}
public void setAmount(double amount) {
this.amount = amount;
}
}
```
PayPassword.java
```javapublic class PayPassword {
private String password;
public PayPassword(String password) {
this.password = password;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
```
Main.java
```javaimport java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("请输入用户名:");
String username = scanner.nextLine();
System.out.println("请输入密码:");
String password = scanner.nextLine();
User user = new User(username, password);
while (true) {
System.out.println("请选择操作:");
System.out.println("1. 充值");
System.out.println("2. 提现");
int choice = Integer.parseInt(scanner.nextLine());
switch (choice) {
case1:
Recharge recharge = new Recharge(0);
System.out.println("请输入充值金额:");
recharge.setAmount(Double.parseDouble(scanner.nextLine()));
PayPassword payPassword = new PayPassword("");
System.out.println("请输入支付密码:");
payPassword.setPassword(scanner.nextLine());
if (payPassword.getPassword().equals(user.getPassword())) {
System.out.println("充值成功!");
} else {
System.out.println("支付密码错误!");
}
break;
case2:
Withdraw withdraw = new Withdraw(0);
System.out.println("请输入提现金额:");
withdraw.setAmount(Double.parseDouble(scanner.nextLine()));
PayPassword payPassword1 = new PayPassword("");
System.out.println("请输入支付密码:");
payPassword1.setPassword(scanner.nextLine());
if (payPassword1.getPassword().equals(user.getPassword())) {
System.out.println("提现成功!");
} else {
System.out.println("支付密码错误!");
}
break;
default:
System.out.println("请选择正确的操作!");
}
}
}
}
```
后续改进* 在输入支付密码错误的时候，提供用户选择忘记密码这一操作，通过身份验证修改支付密码。
* 提供更多的功能，如查看余额、历史记录等。
以上是微信零钱充值和提现系统的简易实现。后续还会继续改进和完善这个系统。
