java银行管理系统代码

很抱歉，我不能提供完整的 Java 银行管理系统的代码，因为这需要根据具体的需求和要求进行设计和开发。但是，以下是一个简单的 Java 银行管理系统的代码框架，可以帮助您开始编写自己的程序：

// 客户类
public class Customer {
    private String name;
    private String address;
    private String phoneNumber;
    private String email;
    private Account account;

    // 构造函数
    public Customer(String name, String address, String phoneNumber, String email) {
        this.name = name;
        this.address = address;
        this.phoneNumber = phoneNumber;
        this.email = email;
        this.account = new Account();
    }

    // 获取客户名
    public String getName() {
        return name;
    }

    // 获取账户信息
    public Account getAccount() {
        return account;
    }

    // 更新账户信息
    public void setAccount(Account account) {
        this.account = account;
    }
}

// 账户类
public class Account {
    private double balance;
    private List<Transaction> transactions;

    // 构造函数
    public Account() {
        this.balance = 0;
        this.transactions = new ArrayList<>();
    }

    // 获取余额
    public double getBalance() {
        return balance;
    }

    // 存款
    public void deposit(double amount) {
        balance += amount;
        transactions.add(new Transaction(amount, "Deposit"));
    }

    // 取款
    public void withdraw(double amount) {
        if (balance >= amount) {
            balance -= amount;
            transactions.add(new Transaction(amount, "Withdraw"));
        } else {
            System.out.println("Insufficient balance");
        }
    }

    // 获取交易记录
    public List<Transaction> getTransactions() {
        return transactions;
    }
}

// 交易类
public class Transaction {
    private double amount;
    private String type;

    // 构造函数
    public Transaction(double amount, String type) {
        this.amount = amount;
        this.type = type;
    }

    // 获取交易金额
    public double getAmount() {
        return amount;
    }

    // 获取交易类型
    public String getType() {
        return type;
    }
}

// 银行类
public class Bank {
    private List<Customer> customers;

    // 构造函数
    public Bank() {
        this.customers = new ArrayList<>();
    }

    // 添加客户
    public void addCustomer(Customer customer) {
        customers.add(customer);
    }

    // 获取客户
    public Customer getCustomer(int index) {
        return customers.get(index);
    }

    // 获取客户数量
    public int getNumOfCustomers() {
        return customers.size();
    }
}

// 测试代码
public class TestBank {
    public static void main(String[] args) {
        Bank bank = new Bank();

        // 添加客户
        Customer customer1 = new Customer("Alice", "123 Main St", "123-456-7890", "alice@example.com");
        Customer customer2 = new Customer("Bob", "456 Elm St", "456-789-0123", "bob@example.com");
        bank.addCustomer(customer1);
        bank.addCustomer(customer2);

        // 存款和取款
        customer1.getAccount().deposit(1000);
        customer1.getAccount().withdraw(500);
        customer2.getAccount().deposit(2000);

        // 打印交易记录
        for (int i = 0; i < bank.getNumOfCustomers(); i++) {
            Customer customer = bank.getCustomer(i);
            System.out.println("Customer: " + customer.getName());
            List<Transaction> transactions = customer.getAccount().getTransactions();
            for (Transaction transaction : transactions) {
                System.out.println(transaction.getType() + " " + transaction.getAmount());
            }
            System.out.println("Balance: " + customer.getAccount().getBalance());
        }
    }
}

以上代码只是一个简单的示例，实际的银行管理系统需要根据具体的需求和要求进行设计和开发。
