Method Overriding in TypeScript
In this article, we will understand some of the necessary details which are associated with Method Overriding, further, we will see how to implement Method Overriding in TypeScript.
- Method Overriding is the process in which a method belonging to the base (or parent) class is overridden by the same method (same method and signature) of the derived (child) class.
- In this process, a child (derived) class method may or may not use the logic defined in the parent (base) class method.
- In order to invoke the methods or properties of the base class, we may use the super keyword which would help us to invoke that particular method or property of the base class into the child class.
- Method Overriding is useful whenever we want to alter the behavior of any method of the parent class in child class.
After analyzing all the basic facts associated with the Method Overriding in TypeScript, let us now see how we could implement Method Overriding in TypeScript with some of the following illustrated examples.
Example 1: In this example, we will declare two classes and inside the parent class we will declare one method which will be overridden by the child class with its own logic.
Name : Rohit, Roll Number : 2, Scores : 96 out of 100 Rohit scores well...
Example 2: In this example, we will display the result of the Parent class method also inside the child’s class overridden parent class method using the super keyword.
Name : Rohit, Roll Number : 2, Scores : 96 out of 100 Rohit is an intelligent boy.. Rohit scores well...
