numKids = numKids + 1;
}

public int getNumKids() {

Answer 1

Step-by-step 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;

}

}
