我的同事建议让一些Eclipse代码格式和警告设置更加严格。这些更改中的大多数都是有意义的，但我在Java中得到了这个奇怪的警告。这是一些重现“问题”的测试代码:packagecom.example.bugs;publicclassWeirdInnerClassJavaWarning{privatestaticclassInnerClass{publicvoiddoSomething(){}}finalprivateInnerClassanInstance;{this.anInstance=newInnerClass();//!!!this.anInstance.doSomething

可能类似于问题，WhycanouterJavaclassesaccessinnerclassprivatemembers?或Accesstosuperclassprivatefieldsusingthesuperkeywordinasubclass.但有一些区别:子类可以访问其父类(并且只能访问最近的父类)的私有(private)成员。给出下面的示例代码:publicclassT{privateintt;classT1{privateintt1;publicvoidtest(){System.out.println(t);}}classT2extendsT1{privateintt2;
