Understands the ambiguity, humans often become confused. In your ownĬlasses, try to use globally unique class names.
This approach makes code easier to maintain because it is easier to find theĬode that implements the class when it is fully qualified. Alternatively, youĬan throw out all the imports and fully qualify all classes in x.y and a.b. And, of course, all references to SomeClass should be disambiguated to either x.y. Some compilers may complain about the clash in SomeClass, even if you never Ambiguous Class import for x.y.SomeClass and a.b.SomeClass // but the compiler won't mind unless you actually use SomeClass. If you were to use SomeClass, which one did you mean? import x. Reference to Object is ambiguous, both class in Variable 'x' is already defined in this method.Īmbiguous class x.y.SomeClass and a.b.SomeClass, C programmers often make this one on multi-line Strings since the
