I am trying to throw an IllegalArgumentException that will catch a negative number and a number over 100 when entered as a test score. When I run the program it still allows negative numbers to b e entered and numbers over 100. I have a TestScore class and InvalidTestScore Class.

import java.util.Scanner;    								// For Scanner class
	
public class TestScores 
{
	private int[] scores; 									// References the score data

public TestScores(int[] s) 	throws IllegalArgumentException			// Constructor accepts array as argument
    {
    	if (s.length < 0)
    		throw new IllegalArgumentException("Score is a negative number.");
    		
    	if (s.length > 100)
    		throw new IllegalArgumentException("Score is greater than 100.");
    	
    		
    	
    	scores = new int[s.length];
    	
  
    	for (int index = 0; index < s.length; index ++)
    		scores[index] = s[index];	
    }

public int getTotal()
    {
    	int total = 0;						// Accumulator
    	for (int value : scores)
    		total += value;
    		
    	return total;							// Return the total
    }
    
    public int getAverage()
    {
    	return getTotal()/ scores.length;
    }
    
   
    
    public static void main(String[] args)
    {
    	final int STUDENT_SCORES = 6;			// Number of array elements
    	
    
    	
    	int[] scores = new int[STUDENT_SCORES];  // Array to hold scores
    	
    
    	getValues(scores);
   	
    	TestScores points = new TestScores(scores);
    	
    	System.out.println();
    	System.out.println("The average test score for six students are " +
    												(points.getAverage()));
    												
    }
    
   
   	
    private static void getValues(int[] array)
    {
    	Scanner keyboard = new Scanner(System.in);					// New Scanner object
    	
    	System.out.println("Enter a whole numeric score for each student.");
    	
    	
 
    	for (int index = 0; index < array.length; index++)				// For Loop
    	{
    		System.out.print("Student " + (index + 1) + ": ");
    		array[index] = keyboard.nextInt();	
    	}
    }
}
