【Tips】抑制警告@SuppressWarnings

@SuppressWarnings

关键字 用途 deprecation 使用了不赞成使用的类或方法时的警告 unchecked 执行了未检查的转换时的警告，例如当使用集合时没有用泛型 (Generics) 来指定集合保存的类型。 fallthrough 当 Switch 程序块直接通往下一种情况而没有 Break 时的警告。 path 在类路径、源文件路径等中有不存在的路径时的警告。 serial 当在可序列化的类上缺少 serialVersionUID 定义时的警告。 finally 任何 finally 子句不能正常完成时的警告。 unused 未使用的方法或类或变量的警告 all 关于以上所有情况的警告。
