Write a class named TestScores. The class constructor should accept an array of test scores as its argument. The class should have a method that returns the average of the test scores. If any test score in the array is negative or greater than 100, the class should throw an IllegalArgumentException. Demonstrate the class in a program.

import java.util.Arrays;

public class TestScores {

   public static float getAverage(float arr[]){

       float total = 0;

       for (float x : arr){

           if (x < 0 || x > 100){

               throw new IllegalArgumentException();

           }

           else{

               total += x;

           }

       }

       return (total / arr.length);

   }

   public static void main(String [] args){

       float arr[] = {1,100,0,43,-1};

       System.out.println(getAverage(arr));

   }

}

In the main method we test our getAverage method with the arr array. You can replace the values in the arr array and test your own values. I hope this helps!
