How do you get the name of the oldest person using split strings and array in Java

bimyou :

I've been staring at this problem for too long.. This is an exercise from https://java-programming.mooc.fi/part-3/4-using-strings and I have to get the name of the oldest person through splitting the strings and finding the name with the oldest age.

> Sample Input: Johnny, 5
>               Rose, 19
>               Sam, 10

Desired Output: Rose

Any help would genuinely be appreciated. Thanks!

import java.util.Scanner;

public class NameOfTheOldest {

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

        String name = "";

        while (true) {

            String input = scanner.nextLine();

            if (input.equals("")) {

                break;

            }

            String[] pieces = input.split(",");

            int age = Integer.valueOf(pieces[1]);

            int oldest = 0;

            if (age > oldest) {

                name = pieces[0];

                oldest = age;

            }
        }

        System.out.println("Name of the oldest: " + name);
    }
}

You placed the variable declaration for oldest inside of the loop, so each time that a new line of input is read, oldest is set back to 0, if you move that outside of the while loop, your code should work properly as is.
