Why is Overriding Used in Java? Method overriding enables Java to accept runtime polymorphism. In simple words, method overriding allows subclasses to implement their own definition of methods inherited from a parent class. This dynamic feature allows developers to customize how methods work, making ...

Method Overriding in JavaMethod overriding is a process of overriding base class method by derived class method with more specific definition.Method overriding performs only if two classes have is-a relationship. It mean class must have inheritance. In other words, It is performed between two ...
I have created another class namedDog, and I want it to inherit from theAnimalclass. When we perform the inheritance process, we would like to use theeat()method inherited from the super class in a way that is suitable for our subclass. Therefore,we change its functionality. In other wor...
it must be reflexive and transitive: that is, x.equals(y) must return the same value as y.equals(x), and if x.equals(y) and y.equals(z), then x.equals(z) must also be true (see below for what this actually means in real terms!). ...

Java Method Override A class inheriting the method from itssuperclasshas the option tooverrideit. The benefit of overriding is the ability to define behavior specific to a particular class. In the case of a concrete subclass, it is forced to implement all methods defined in abstract class if...
As we know that PHP is not type strict, means if we implement overloading in C++ or Java, the function will look like add(int,float) is different from add(float,int) or even add(float,int,int) but it is not possible in PHP. Actually polymorphism is not easy in PHP. In this post...
该类不需要提供「逻辑相等」测试。例如,java.util.regex.Pattern可以覆盖 equals 来检查两个 Pattern 实例是否表示完全相同的正则表达式,但设计人员认为客户端不需要或不需要这个功能。在这种情况下,从 Object 继承的 equals 实现是理想的。 A superclass has already overridden equals, and the superclass behavior ...
Declaring a method in sub class which is already present in parent class is known as method overriding. Overriding is done so that a child class can give its own implementation to a method which is already provided by the parent class. In this case the m
