The Person Class Averaging the Three Ages

Can you tell what I should put in my code so that my class testperson actually averages the three ages??!! I know that values must be declared somewhere in testperson or something like that. Here is my code so far:

Java Code:

public class TestPerson extends AverageThreeInts
{
public static void main(String[] args)
{
 
          

Person person1 = new Person("John", "Smith", 32);
Person person2 = new Person("Jane", "Doe", 25);
Person person3 = new Person("Tommy", "Banks", 42);
person1.printName();
person1.printAge();
person1.printAgeGroup();

person2.printName();
person2.printAge();
person2.printAgeGroup();

person3.printName();
person3.printAge();
person3.printAgeGroup();
}

public int getAverageAge(Person[] people)

{
  int sum = 0;
 
                for (int i : values) {
                        sum += i;
                }
 
                return (sum / values.length);

  
}




}

Java Code:

import java.util.Scanner;
 
public class AverageThreeInts{
 
  public static void main(String[] args) {
 
                Scanner scanner = new Scanner(System.in);
 
                int inputs = 2;
                int[] values = new int[3];
 
                while (inputs > -1) {
                        // It's a good idea to prompt for input before trying to get the next input from the user
                        System.out.println("Please enter an integer.");
                        values[inputs] = scanner.nextInt();
 
                        inputs--;
                }
 
                // It's also a good idea to give a clear message about what the output is
                System.out.println("The averge of the integers entered is: " + averageValue(values));
        }
 
        private static int averageValue(int[] values) {
                int sum = 0;
 
                for (int i : values) {
                        sum += i;
                }
 
                return (sum / values.length);
        }
 
}
