Java 实现银行账户类：含异常处理与日志输出的账户操作详解

```java class BankAccount { private int balance; // 无参构造方法，将账户余额初始化为 0 public BankAccount() { balance = 0; } // 带一个参数的构造方法，将账户余额初始化为输入的参数 public BankAccount(int initialBalance) { balance = initialBalance; } // 返回账户余额 public int getBlance() { return balance; } // 提取方法 public int withdraw(int amount) { if (balance >= amount) { balance -= amount; return balance; } else { System.out.println("账户余额不足，无法提取！"); return balance; } } // 存款方法 public void deposit(int amount) { balance += amount; } } public class Main { public static void main(String[] args) { java.util.Scanner scanner = new java.util.Scanner(System.in); System.out.print("请输入账户余额: "); int initialBalance = scanner.nextInt(); BankAccount account = new BankAccount(initialBalance); System.out.print("请输入提取额度: "); int withdrawAmount = scanner.nextInt(); int balanceAfterWithdraw = account.withdraw(withdrawAmount); System.out.print("请输入存款额度: "); int depositAmount = scanner.nextInt(); account.deposit(depositAmount); System.out.println("初始账户余额: " + account.getBlance()); System.out.println("提取 " + withdrawAmount + " 后的账户余额: " + balanceAfterWithdraw); System.out.println("存入 " + depositAmount + " 后的账户余额: " + account.getBlance()); } } ``` 注意逻辑点： 1. 对于输入的金额数据，需要做好异常处理，防止用户输入非法数据。 2. 在 withdraw 方法中，如果余额不足提取，考虑返回一个特定的标识值，而不仅仅是输出提示信息。 3. 可以添加一些日志输出，方便跟踪程序的执行过程和账户操作的细节。 ######[AI写代码神器 | 484点数解答 | 2025-05-05 17:07:36]
