Why can’t violation parameter types in Java be overridden?

Java allows return types to be covariant when overriding superclass methods

Why is it not allowed to use opposite parameter types when overriding methods?

Solution

Because this is called overloading

In particular, the return type can be covariant because it is not considered when overloaded, so it still conforms to the implementation of the superclass or interface Parameters will be considered when overloading You can use number dosomethingwithnumber (integer value) and number dosomethingwithnumber (number value) for optimization
