2 The signature of m1 is a subsignature ( 842) of the signature of m2 If a method declaration d1 with return type R1 overrides or hides the declaration of another method d2 with return type R2, then d1 must be return-type-substitutable ( 845) for d2, or a compile-time error occurs Furthermore, if R1 is not a subtype of R2, an unchecked warning must be issued Moreover, a method declaration must not have a throws clause that con icts ( 846) with that of any method that it overrides; otherwise, a compile-time error occurs It is a compile time error if a type declaration T has a member method m1 and there exists a method m2 declared in T or a supertype of T such that all of the following conditions hold: m1 and m2 have the same name m2 is accessible from T

Methods are overridden on a signature-by-signature basis If, for example, an interface declares two public methods with the same name, and a subinterface overrides one of them, the subinterface still inherits the other method An interface inherits from its direct superinterfaces all methods of the superinterfaces that are not overridden by a declaration in the interface It is possible for an interface to inherit several methods with override-equivalent signatures ( 842) Such a situation does not in itself cause a compile-time error The interface is considered to inherit all the methods However, one of the inherited methods must must be return type substitutable for any other inherited method; otherwise, a compile-time error occurs (The throws clauses do not cause errors in this case) There might be several paths by which the same method declaration is inherited from an interface This fact causes no dif culty and never of itself results in a compile-time error 942 Overloading If two methods of an interface (whether both declared in the same interface, or both inherited by an interface, or one declared and one inherited) have the same name but different signatures that are not override-equivalent ( 842), then the

method name is said to be overloaded This fact causes no dif culty and never of itself results in a compile-time error There is no required relationship between the return types or between the throws clauses of two methods with the same name but different signatures that are not override-equivalent 943 Examples of Abstract Method Declarations The following examples illustrate some (possibly subtle) points about abstract method declarations 9431 Example: Overriding

Methods declared in interfaces are abstract and thus contain no implementation About all that can be accomplished by an overriding method declaration, other than to af rm a method signature, is to re ne the return type or to restrict the exceptions that might be thrown by an implementation of the method Here is a variation of the example shown in ( 8431):
