Is overriding possible in inheritance?
The ability of a subclass to override a method allows a class to inherit from a superclass whose behavior is “close enough” and then to modify behavior as needed. The overriding method has the same name, number and type of parameters, and return type as the method that it overrides.
Can we do method overriding without inheritance?
If a method cannot be inherited, then it cannot be overridden. A subclass within the same package as the instance’s superclass can override any superclass method that is not declared private or final. A subclass in a different package can only override the non-final methods declared public or protected.
How can we override a method in inheritance?
When a method in a subclass has the same name, same parameters or signature, and same return type(or sub-type) as a method in its super-class, then the method in the subclass is said to override the method in the super-class. Method overriding is one of the way by which java achieve Run Time Polymorphism.
Is overriding possible in same class?
The answer is No, you cannot override the same method in one class. The anonymous inner class is a different class.
What’s the difference between overriding and overloading inheritance methods?
In the inheritance hierarchy, superclass and subclass methods can be overridden and overloaded. There are the following differences between overriding and overloading a method: when overloaded, the methods of the superclass and subclass have the same name but different signatures of parameters types.
When does an overriding of a method occur?
1. What is an overriding of method? Method overriding is a case in which the subclass and superclass contain methods that have the same name and type signature (Figure 1). Overriding of a method occurs when classes form an inheritance hierarchy.
Which is an example of overriding in Java?
An example of overriding the method () method of superclass A in subclass B. In Figure 1, class B inherits (extends) class A. Class A is a superclass for class B. In subclass B, a method is declared with the same name as in superclass A. So, in this case, the method named method () of superclass A is overridden in subclass B.
When do you override a method in a subclass?
Method overriding is a case in which the subclass and superclass contain methods that have the same name and type signature (Figure 1). Overriding of a method occurs when classes form an inheritance hierarchy. Figure 1. An example of overriding the method () method of superclass A in subclass B
