Not quite sure why any IDE would let you choose such a combination (might be worth reporting a bug on it), as this is not a valid combination. 不太确定为什么任何IDE都会允许您选择这样的组合（可能值得报告其错误），因为这不是有效的组合。 You cannot use language features from a higher version than your SDK - the compiler just won't know how to treat the new syntax. 您不能使用比SDK更高版本的语言功能-编译器只是不知道如何对待新语法。
