java中的参数多态性

Question

什么是java中的参数多态

Answer 1

Answer 2

Sometimes, overloading is also reffered as parametric polymorphism as far as you would have methods with the same name but with different parameters. Usually those methods have the same purpose so you have different (polymorph) ways of calling the same name.
