Solution
The "this" keyword is used to avoid naming conflicts.
Here's a step-by-step explanation:
-
In Java, "this" is a reference variable that refers to the current object.
-
It is primarily used in three situations:
- First, it can be used to refer to the current class instance variable if a method or constructor of this class has a parameter with the same name as an instance variable.
- Second, it can be used to invoke the current class method.
- Third, it can be used to return the current class instance.
-
By using the "this" keyword, we can distinguish between class attributes and parameters with the same name. This is how it helps to avoid naming conflicts.
For example, if you have a class like this:
public class Student {
String name;
public Student(String name) {
this.name = name;
}
}
In the constructor, "name" is a parameter and "this.name" is the instance variable. The "this" keyword is used to distinguish between the two and avoid a naming conflict.
