Just need some help with java Math.max and Math.min when user inputs random numbers.

I am trying to just understand, if a user inputs random numbers 0 through 100 how does Math.max and Math.min work.
I know how to code if I know the numbers.
`Inline Code Example Here'
int x = 67;
int y = 23;
int y = 23;
int max = Math.max(x, y) //max is 67
int min = Math.min(x, y) //min is 23

Here is where I have gotten with my code:

import java.util.Scanner;
import java.lang.Math;

public class TestScoreApp
{
    public static void main(String[] args)
    {
        // display operational messages
        System.out.println("Please enter test scores that range from 0 to 100.");
        System.out.println("To end the program enter 999.");
        System.out.println();  // print a blank line

        // initialize variables and create a Scanner object
        int testScore = 0;        
        int max = Math.max(testScore, testScore);
        int min = Math.min(testScore, testScore);
        double scoreTotal = 0;
        int scoreCount = 0;

        Scanner sc = new Scanner(System.in);

        // get a series of test scores from the user
        while (testScore != 999)
        {
            // get the input from the user
            System.out.print("Enter score: ");
            testScore = sc.nextInt();

            // accumulate score count and score total
            if (testScore <= 100)
            {
                scoreCount += 1;
                scoreTotal += testScore;
            }
            else if (testScore != 999)
                System.out.println("Invalid entry, not counted");
        }

        // display the score count, score total, and average score
        double averageScore = scoreTotal / scoreCount;
        String message = "\n" +
                         "Score count:   " + scoreCount + "\n"
                       + "Score total:   " + scoreTotal + "\n"
                       + "Average score: " + averageScore + "\n";
        String message2 = "\n" +
                            "Minimum score: " + min + "\n"
                        +   "Maximum score: " + max;
        System.out.println(message);
        System.out.println(message2);
    }
}

I think I figured it out? Does this look better?

import java.util.Scanner;
import java.lang.Math;

public class TestScoreApp
{
    public static void main(String[] args)
    {
        // display operational messages
        System.out.println("Please enter test scores that range from 0 to 100.");
        System.out.println("To end the program enter 999.");
        System.out.println();  // print a blank line

        // initialize variables and create a Scanner object
        int scoreTotal = 0;
        int scoreCount = 0;
        int testScore = 0;
        int minScore = 0;
        int maxScore = 100;       

        minScore = Math.min(testScore, minScore);
        maxScore = Math.max(testScore, maxScore);        
        Scanner sc = new Scanner(System.in);

        // get a series of test scores from the user
        while (testScore != 999)
        {
            // get the input from the user
            System.out.print("Enter score: ");
            testScore = sc.nextInt();

            // accumulate score count and score total
            if (testScore <= 100)
            {
                scoreCount += 1;
                scoreTotal += testScore;

                if(minScore < testScore) {
                     minScore = testScore;
                     }
                     if(maxScore > testScore) {
                     maxScore = testScore;
                     }
            }
            else if (testScore != 999)
                System.out.println("Invalid entry, not counted");
        }

        // display the score count, score total, and average score
        double averageScore = scoreTotal / scoreCount;
        String message = "\n" +
                         "Score count:   " + scoreCount + "\n"
                       + "Score total:   " + scoreTotal + "\n"
                       + "Average score: " + averageScore + "\n";
        String message2 = "\n" +
                            "Minimum score: " + minScore + "\n"
                        +   "Maximum score: " + maxScore;
        System.out.println(message);
        System.out.println(message2);
    }
}

It would just return max - the greater of the two values and min - the smaller of them , such as

public int findMin(int a, int b)
    if(a>b) return b;
    else return a;

Likewise for max
