别再写try-catch了，推荐用这一种方式
使用 Result 类型替代 try-catch
传统try-catch在处理异常时容易导致代码嵌套过深，可读性降低。采用Result类型（或类似模式）可以将错误处理逻辑扁平化，提升代码的清晰度和可维护性。
定义 Result 类型
public sealed interface Result<T, E> { record Success<T, E>(T value) implements Result<T, E> {} record Failure<T, E>(E error) implements Result<T, E> {} }使用 Result 包装可能失败的操作
public Result<Integer, String> divide(int a, int b) { return b == 0 ? new Result.Failure<>("Division by zero") : new Result.Success<>(a / b); }链式处理结果
通过模式匹配或链式调用处理成功和失败情况：
divide(10, 2) .ifSuccess(result -> System.out.println("Result: " + result)) .ifFailure(error -> System.err.println("Error: " + error));结合 Optional 进行空安全处理
Optional可以避免NullPointerException，与Result结合能更安全地处理潜在异常：
public Optional<Result<Integer, String>> safeDivide(int a, int b) { return Optional.ofNullable(b) .filter(divisor -> divisor != 0) .map(divisor -> new Result.Success<>(a / divisor)) .or(() -> Optional.of(new Result.Failure<>("Invalid divisor"))); }使用函数式编程库
已有库（如 Vavr、Arrow）提供了成熟的Either或Try类型，可直接使用：

// Vavr 示例 Either<String, Integer> result = Try.of(() -> 10 / 2) .toEither() .mapLeft(Throwable::getMessage);优势总结
- 显式错误处理：强制调用方处理可能的失败情况，避免遗漏异常。
- 代码扁平化：减少嵌套，提升可读性。
- 组合性：支持链式操作，易于组合多个可能失败的操作。
通过Result或类似模式，可以更优雅地替代传统try-catch，适用于现代 Java 或其他支持代数数据类型的语言。
