定义一个银行账户类,该类的属性有:账户、存款余额;方法有:存款、取款、查询;定义一个描述取款数目超出余额的异常,在取款方法中抛出该异常。在测试类的main方法中创建一个银行帐户对象,用该对象多次调用取款方法,当余额不足时提示“余额不足!”。

.Java定义一个银行账户类,包括姓名卡号密码余额等属性,定义存款取款转账等方法.
在Java中,你可以定义一个名为`BankAccount`的类来模拟一个简单的银行账户,包含相关的属性和方法。以下是该类的一个基本设计:
```java
public class BankAccount {
// 属性
private String accountHolderName;
private String accountNumber;
private String password;
private double balance;
// 构造函数
public BankAccount(String name, String accountNum, String pass, double initialBalance) {
accountHolderName = name;
accountNumber = accountNum;
password = pass;
balance = initialBalance;
}
// 提供getter和setter方法
public String getAccountHolderName() {
return accountHolderName;
}
public void setAccountHolderName(String accountHolderName) {
this.accountHolderName = accountHolderName;
}
public String getAccountNumber() {
return accountNumber;
}
public void setAccountNumber(String accountNumber) {
this.accountNumber = accountNumber;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public double getBalance() {
return balance;
}
public void setBalance(double balance) {
this.balance = balance;
}
// 方法 - 存款、取款、转账
public void deposit(double amount) {
if (amount > 0) {
balance += amount;
} else {
throw new IllegalArgumentException("Deposit amount must be positive.");
}
}
public void withdraw(double amount) {
if (amount <= balance) {
balance -= amount;
} else {
System.out.println("Insufficient funds.");
}
}
public boolean transfer(BankAccount recipient, double amount) {
if (amount <= balance && amount > 0) {
withdraw(amount);
recipient.deposit(amount);
return true;
} else {
return false;
}
}
}
```
#案例:银行账户类,加密初始化账号、余额,定义公共方法查看两个属性,定义存款取款方法 Python
在Python中,我们可以创建一个名为`BankAccount`的类来模拟银行账户的行为。这个类可以包含私有变量来存储账号(encrypted_account)和余额(balance),并通过装饰器或特殊方法(如`__init__`, `__str__`, `deposit`, `withdraw`)来进行相应的操作。以下是该类的一个简单示例:
```python
import hashlib
class BankAccount:
def __init__(self, account_num, initial_balance):
self._encrypted_account = self.encrypt_account(account_num)
self.balance = initial_balance
@staticmethod
def encrypt_account(account_num):
return hashlib.sha256(account_num.encode()).hexdigest()
def view_details(self):
print(f"Encrypted Account: {self._encrypted_account}")
print(f"Balance: {self.balance}")
def deposit(self, amount):
if amount > 0:
self.balance += amount
print(f"Deposited: {amount}. New Balance: {self.balance}")
else:
print("Invalid deposit amount.")
def withdraw(self, amount):
if amount <= self.balance:
self.balance -= amount
print(f"Withdrew: {amount}. New Balance: {self.balance}")
else:
print("Insufficient balance.")
# 使用示例
account = BankAccount("123456", 1000)
account.view_details()
account.deposit(500)
account.withdraw(200)
```
在这个例子中,`__init__`方法用于初始化账户,`encrypt_account`是一个静态方法用于对账户号码加密,`view_details`方法显示账户详细信息,而`deposit`和`withdraw`方法分别用于存款和取款操作。
