The this keyword in Java serves as a reference to the current object. It enhances code readability and ensures precise control over constructors, instance variables, and method calls. This article explores the versatility of this with multiple examples. 1. Referencing the Current Class Instance

Java is a widely-used programming language, and developers often encounter interview questions related to its core concepts. One such question is: What is the purpose of the this keyword in Java?

The solution is the “this” keyword Append both ‘a’ and ‘b’ with the Java this keyword followed by a dot (.) operator. During code execution when an object calls the method ‘setdata’. The keyword ‘this’ is replaced by the object handler “obj.” (See the image below). So now the compiler knows, The ‘a’ on the left-hand side is an Instance variable.

In Java, "this" is a reference variable that refers to the current object, or can be said "this" in Java is a keyword that refers to the current object instance. It is mainly used to, To differentiate between the local and instance variables. Using "this" reference can improve code readability and reduce naming conflicts.
