This Vs Super Comparison

Java Keywords: this vs super Overview

In Java, the keywords this and super are crucial for handling class inheritance and object references. The keyword this refers to the current instance of a class. It’s commonly used to distinguish between class fields and parameters with the same name. For instance, in class A, this.x = x; assigns the constructor parameter to the instance variable. On the other hand, super is used to refer to the parent class, especially when calling a superclass constructor or method. In class B, which extends class A, super(x); initializes the inherited member x using the parent constructor. Moreover, this is useful for internal reference within a class, while super enables access to base class functionality. Furthermore, these keywords help avoid ambiguity, promote code reuse, and support clean object-oriented design. Therefore, understanding this vs super is fundamental to writing clear and maintainable Java applications.

Key Features of Java Keywords: this vs super
