Question

I keep getting an Error after I ask the user for test scores. What is missing?
package testscores;
import java.util.Scanner;
public class TestScores {
/**
* @param args the command line arguments
*/
private double[] scores;
  
public TestScores(double[] score) throws IllegalArgumentException
{
scores = new double[scores.length];
for (int i = 0; i < scores.length; i++)
{
if (score[i] < 0 || score[i] > 100){

throw new IllegalArgumentException();
}
scores[i]=score[i];
  
}
  
}
public double getAverage()
{
int sum=0;
for(int i=0;i<scores.length;i++)
sum+=scores[i];
return sum/scores.length;
}
public static void main(String[] args) {
// TODO code application logic here
Scanner keyboard=new Scanner(System.in);

System.out.println("How many test scores are there?");
int length=keyboard.nextInt();
double scores[]=new double[length];
for(int i=0;i<scores.length;i++){
System.out.println("Enter an test score:");
scores[i]=keyboard.nextDouble();
}

try{
TestScores score=new TestScores(scores);
System.out.println("The Average is: "+ score.getAverage());
}
catch(IllegalArgumentException e){
System.out.println("Invaild:"+e.getMessage());
}
}
}

public class InvaildTestScores extends IllegalArgumentException {
public InvaildTestScores(String error){
super("All the numbers need to be between 0-100 only.");
}
}

Change statement 
scores = new double[scores.length];
to 
scores = new double[score.length];
