Im trying to create a code that records and stores the identity and the amount of milk produced by everytime a cow is milked, 2 times a day, and for 1 week( 7 days) It also needs to show the cow that has milked the most for 1 week, and all the cows that have produced milk below 12 litres. here is simplified code where the error is genearted:

import java.util.Scanner;

public class test
{
public static void main(String[] args)
    {
    Scanner na = new Scanner(System.in);
    System.out.println("Please enter number of cows: ");
    int num = na.nextInt();

    int[] ID =new int[num];
    double[] Milk = new double[num];
    double[] Milk2 = new double[num];
    double[] total = new double[num];
    double[] Average = new double[num];
    double[] Lcows = new double[num];
    double[] Lmilks = new double[num];

    Scanner input = new Scanner(System.in);

    for (int i = 0; i < num; i++)
        {
        System.out.println("Enter cow ID no." + (i+1));
        ID[i] = input.nextInt();

        if (ID[i] < 1000 && ID[i] > 0)
            {
            for (int u = 0; u < 7; u++)
                {
                System.out.println("DAY " + (u+1));
                System.out.println("enter milk produced for first session");
                Milk[u] = input.nextDouble();
                total[i] = total[i] + Milk[u];// error can be found here.
                System.out.println("enter milk produced for second session");
                Milk2[u] = input.nextDouble();
                total[i] = total[i] + Milk2[u];// here as well.

                }
            }
        }
    }
}

I was testing out the code but got this error message:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1 at test.main(test.java:37)

I have no idea what i am doing wrong! I need your smart help :):
