这样是不行的，编译器会拒绝编译。其实，想一下，就能明白，这个时候Child应该取父类中字段的值还是接口中字段的值呢，编译器是不知道的，所以不能编译。其实，如果是在编译期，代码开发工具会给一条这样的报错信息：Reference to 'a' is ambiguous, both 'Parent.a' and 'Interface0.a' match.如果强制执行这...

如果在编译器看来,同时有多个方法具有相同的优先权,它就会陷入无法就到底调用哪个方法作出一个选择的状态。在这样的时候,它就会产生一个“reference to 被调用的方法名 is ambiguous”的编译错误,并耐心的等候作了一些修改,足以免除它的迷惑的新源代码的到来。 在引入了Varargs机制之后,这种可能导致迷惑的情况,又增加...
error:referencetomethodNameis ambiguous both methodmethodName(int)inClassNameand methodmethodName(double)inClassNamematch 1. 2. 2. 检查方法参数类型 根据报错信息,我们可以看到出现了方法重载的情况,即存在多个方法名称相同但参数类型不同的方法。因此,我们需要检查方法参数的类型,确保方法的参数类型是不同的。

In this case, a compile-time error occurs, because the reference is now ambiguous. The ambiguous reference to theProxyclass can be resolved in favor ofjava.lang.reflect.Proxyby adding a third import statement: import java.lang.reflect.Proxy; ...
