Question

I need help fixing this java code described below:

import java.util.Scanner;
import java.util.InputMismatchException;

public class NameAgeChecker {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);

String inputName;
int age;

inputName = scnr.next();
while (!inputName.equals("-1")) {
// FIXME: The following line will throw an InputMismatchException.
// Insert a try/catch statement to catch the exception.
age = scnr.nextInt();
System.out.println(inputName + " " + (age + 1));

inputName = scnr.next();
}
}
}

The given program reads a list of single-word first names and ages (ending with -1), and outputs that list with the age incremented. The
program fails and throws an exception if the second input on a line is a String rather than an Integer. At FIXME in the code, add a try/catch
statement to catch java.util.InputMismatchException, and output 0 for the age.
Ex: If the input is:
Lee 18
Lua 21
Mary Beth 19
Stu 33
-1
then the output is:
Lee 19
Lua 22
Mary 0
Stu 34
