Author	Topic: Overloading Signature
Divakar greenhorn	posted March 09, 2000 09:26 AM Which of the following statements are true? a) Overridden methods have the same method name and signature b) Overloaded methods have the same method name and signature c) Overridden methods have the same method name and different signature d) Overloaded methods have the same method name and different signature My answers (a) and (d). Can overloaded methods have same signatures?? Signature of overloaded method will include its name argument type and not its return type.Overloaded method means same method name and differrent arguments. If you change the argument the signature will also change ,am I right??
maha anna bartender	posted March 09, 2000 10:40 AM Yes, you are right. And 1 more thing. Even in JLS this is not specified clearly. The order of the arguments is also VERY IMPORTANT. For example void m1(int i,float f) {} void m1(float f,int i) {} These 2 methods are NOT OVERRIDDEN. Instead they are OVERLOADED. Also note that when invoking m1(10,10f); //Ok m1(10f,10); //Ok m1(10,10); //Compiler will shout!!! It is ambiguous. regds maha anna [This message has been edited by maha anna (edited March 09, 2000).]
jala greenhorn	posted March 09, 2000 08:55 PM stupid question does the method signature include the access modifier(public,private...)
Joe Java ranch hand	posted March 09, 2000 09:34 PM No, thats not a stupid question at all, but a stupid answer is nope! Whats more i'm also too lazy to elaborate.
Tony Alicea sheriff	posted March 10, 2000 01:20 PM No, the signature does not include the access modifiers nor the return type. Only the name of the method, and the types, number and order of the arguments.
