复制代码 返回null或默认值:在Enum类的方法中如果无法处理异常情况,可以返回null或默认值。例如: public enum ErrorCode { SUCCESS, INVALID_INPUT, DATABASE_ERROR; public static ErrorCode getErrorCode(String code) { try { return ErrorCode.valueOf(code); } catch (IllegalArgumentException e) { return...

当然在不同的语言中也未必是绝对的，如在Rust中，由于enum的特性比较丰富，所以在Rust下使用enum来实现error code可能是比较好的选择。#[derive(Debug)]enum ErrorMessages { AppLogin404 { email: String, }, AppLogin405(String),}impl fmt::Display for ErrorMessages { fn fmt(&self, f: ...
是识别enum关键字的,但是假如我选择第二个或者默认的jdk1.8,那就不行了,后来发现java compiler compliance level中的最高上限也才1.7,所以,两种解决方法(原理是一样的),一是将compiler compliance level设置到1.5以上,另一个就是把.settings下的org.eclipse.jdt.core修改为以下内容: ...
