What is the purpose of method overriding?
Assuming class A has a method named getXXX() and class B is a sub class of class A. Now, if we write a method with the same name getXXX() in class B, with exactly the same signature as class A, it is called overriding a method. The method getXXX() in class A becomes the overridden method.
In java why method defined in super class need not to defined in subclass?
In Java, or in any object oriented language such as C++, a method defined in super (parent) class does not need to be defined in a subclass, because that is the primary purpose of inheritance. Object oriented programming allows you to define and declare a class that implements the behavior for an object. Inheritance allows you to refine, or subclass, that class by "reusing" all of the functionality of the parent class into the sub class, adding additional definition and declaration for the sub class. If the subclass needs to change a parent class method, it can overload that method. This is called abstraction.
How do you call a method from another class in Java?

Does Every class has a toString method and an equals method inherited from the Object class?

What is function overriding in Java?
Method overriding is similar to method overloading, with a small difference. In overriding, a method in a parent class is overridden in the child class. The method in the child class will have the same signature as that of the parent class. Since the method in the child class has the same signature & name as the method of its parent class, it is termed as overriding. In situations where you may have to explicitly call the parent class method you can use the "super" keyword and for explicitly calling the current objects method you can use the "this" keyword.
