How to solve the invalidity of java method overloading

Overloading is invalid

1. When talking about the parameter list, the return type of the method is not discussed.

2. If two methods have the same name, the same parameters and different return types, then this is not a valid method overload and will result in a compilation error.

int add(int, int)
float add(int, int)

Overloading Description

Overloading Note
