方法重写(Method Overriding):如上所述,方法重写发生在子类和父类之间,子类提供与父类方法签名相同的方法实现。 方法重载(Method Overloading):方法重载允许在同一个类中定义多个同名方法,只要它们的参数列表不同。方法重载主要用于提供不同的方式来执行相似的操作,但它与面向对象编程中的继承无关。简单...
In Java, abstract classes are created to be the superclass of other classes. And, if a class contains an abstract method, it is mandatory to override it. We will learn more about abstract classes and overriding of abstract methods in later tutorials. Also Read: Java Method Overloading Previ...

Python has no standard mechanism by which to guarantee that (1) a method that previously overrode an inherited method continues to do so, and (2) a method that previously did not override an inherited will not override now. This opens the door for subtle problems as class hierarchies evolve...

final call to it. If one or more data structures that are being built already hold the object, then it is not reasonable to have to track down the object and try to swap in a new copy everywhere. There should be a simple way to have the existing object's attributes update in-place....
Method Overriding Method Overloading: Method Overloading is the class having methods that are the same name with different arguments. Arguments different will be based on a number of arguments and types of arguments. It is used in a single class. ...
