这个重载方法在不同的类和不同的签名中具有相同的名称吗? [英] Is this Overloading, methods with same name in different classes and different signature?

问题描述

如果我在Java中具有以下代码:

If I have the following code in Java:

class A {

    public int add(int a , int b) {
        return (a+b);
    }
}

class B extends A {
    public float add(float a , float b) {
        return (a+b);
}

在这种特殊情况下，子类没有完全覆盖基类的add函数，因为它们具有不同的签名，并且仅当它们在相同范围内时，才会出现重载的概念.那么，子类B中的函数add(float , float)是否被视为一个全新的函数，并且重载和重写的概念不适用于它?并使用静态绑定"还是动态绑定"?

In this particular case the sub-class isn't exactly overriding the base class's add function as they have different signatures and the concept of overloading occurs only if they are in the same scope. So, is the function add(float , float) in the sub-class B treated as an entirely new function and the concept of overloading and overriding is not applicable to it? And does it use 'Static binding' or 'Dynamic Binding'?

推荐答案

类b中的方法add是类a中的重载.不是替代.覆盖只是原始add方法的另一种实现.

Method add in class b is an overload of add in class a. Not an override. An override would just be a different implementation of the original add method.
