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

So, what is your problem? Please be specific and show examples of why these methods aren't working for you.

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
