What is the purpose of ‘this’ keyword in java?

Comment

In Java, ‘this’ keyword refers to current instance of the object.

It is useful for differentiating between instance variables and local

variables.

It can be used to call constructors. Or it can be used to refer to the

instance.

In case of method overriding, this is used for falling the method of

current class.

public class Main {
  int x;

  // Constructor with a parameter
  public Main(int x) {
    this.x = x;
  }

  // Call the constructor
  public static void main(String[] args) {
    Main myObj = new Main(5);
    System.out.println("Value of x = " + myObj.x);
  }
}
