Print person1's kids, call the incNumKids() method, and print again, outputting text as below. End each line with a newline. Sample output for below program with input 3:
Kids: 3
New baby, kids now: 4
// Code from file PersonInfo. java
public class PersonInfo {
private int numKids;

public void setNumKids(int setPersonsKids) {
numKids = setPersonsKids;
}

public void incNumKids() {
numKids = numKids + 1;
}

public int getNumKids() {
return numKids;
}
}
// end

// Code from file CallPersonInfo. java
import java. util. Scanner;

public class CallPersonInfo {
public static void main(String [] args) {
Scanner scnr = new Scanner(System. in);
PersonInfo person1 = new PersonInfo();
int personsKid;

personsKid = scnr. nextInt();

person1.setNumKids(personsKid);

/* Your solution goes here */

}
}
// end

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;

   }

}

none because it's so obvious
