Question
*****************READ PROBLEM BEFORE ANSWERING*********************I am tired of people just pasting in programs they find on google without checking anything themselves.
This is my problem. My AuthenticateMain is unable to invoke the method isValid from Authenticate.
DO NOT ANSWER IF YOU DONT READ MY QUESTION

import java.util.Scanner;
public class AuthenticateMain

public static void main(String[] args)

int[] actual_password = {6, 6, 5, 2, 0};
int[] random_nums = new int[10];
int[] entered_digits = new int[actual_password.length];
for (int i=0; i < 10; i++)
{
random_nums[i] = (int) (Math.random() * 3) + 1;
}
System.out.println("Welcome! To log in, enter the random digits from 1-3 that");
System.out.println("correspond to your PIN number.");
System.out.println();
System.out.println("PIN digit: 0 1 2 3 4 5 6 7 8 9");
System.out.print("Random #: ");
for (int i=0; i<10; i++)

entered_digits[Index++] = s.charAt(0) - '0';
}
boolean isCorrect = isValid (actual_password, entered_digits, random_nums);
if (isCorrect)

System.out.println("Correct! You may now proceed.");
