Explanation:

The following code was written in Java and modifies the code so that for the given input such as 3 it outputs the exact information shown in the sample output.

import java.util.Scanner;

class CallPersonInfo {

   public static void main(String [] args) {

       Scanner scnr = new Scanner(System.in);

       PersonInfo person1 = new PersonInfo();

       int personsKid;

       System.out.println("How many kids do you have:");

       personsKid = scnr.nextInt();

       person1.setNumKids(personsKid);

       /* Your solution goes here */

       System.out.println("Kids: " + person1.getNumKids());

       person1.incNumKids();

       System.out.println("New Baby, kids now: " + person1.getNumKids());

   }

}

class PersonInfo {

   private int numKids;

   public void setNumKids(int setPersonsKids) {

       numKids = setPersonsKids;

   }

   public void incNumKids() {

       numKids = numKids + 1;

   }

   public int getNumKids() {

       return numKids;

   }

}
