Question

Create a class that has a method that uses the ‘this’ keyword as the return statement. This method (called increment( ) in the class that you have just created ) increments the private integer field (private i ) in the class.   In the main ( ) method, if you increment (using the ‘this’ with increment() call) four times, you should see the following display:

i is = 4

Thank You

Answer 1

public class Main
{
private int i;
Main()
{
i=0;
}
public void increment()
{
this.i = this.i+1;
}
public int get()
{
return this.i;
}
  
   public static void main(String[] args) {
   Main n = new Main();
   n.increment();
   n.increment();
   n.increment();
   n.increment();//incrementing 4 times
       System.out.println("i is ="+n.get()+"\nThank You");
   }
}

output:

i is =4
