可以的,以下是一个简单的Java银行业务程序的示例:
```java
import java.util.Scanner;
public class Bank {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
Account account = new Account(1000); // 初始化账户余额为1000元
while (true) {
System.out.println("请选择操作:"); System.out.println("1. 存款");
System.out.println("2. 取款");
System.out.println("3. 兑换货币");
System.out.println("4. 查看账户信息");
System.out.println("5. 退出");
int choice = input.nextInt();
switch (choice) {
case 1:
System.out.print("请输入存款金额:");
double depositAmount = input.nextDouble();
account.deposit(depositAmount);
break;
case 2:
System.out.print("请输入取款金额:");
double withdrawAmount = input.nextDouble();
account.withdraw(withdrawAmount);
break;
case 3:
System.out.print("请输入兑换货币金额:");
double exchangeAmount = input.nextDouble();
System.out.print("请输入兑换汇率:");
double exchangeRate = input.nextDouble();
account.exchange(exchangeAmount, exchangeRate);
break;
case 4:
account.showInfo();
break;
case 5:
System.exit(0);
default:
System.out.println("输入错误,请重新输入!");
}
}
}
}
class Account {
private double balance; // 账户余额
public Account(double balance) {
this.balance = balance;
}
public void deposit(double amount) {
balance += amount;
System.out.println("存款成功,当前余额为:" + balance + "元");
}
public void withdraw(double amount) {
if (balance >= amount) {
balance -= amount;
System.out.println("取款成功,当前余额为:" + balance + "元");
} else {
System.out.println("余额不足,取款失败!");
}
}
public void exchange(double amount, double rate) {
double exchangedAmount = amount * rate;
balance += exchangedAmount;
System.out.println("兑换成功,当前余额为:" + balance + "元");
}
public void showInfo() {
System.out.println("当前账户余额为:" + balance + "元");
}
}
```
这个程序包括存款、取款、兑换货币和查看账户信息等操作。你可以根据自己的需求进行修改和扩展。
