Connect 4 - Program Registers If See Four Integers Of Same Value

For the latest assignment, my instructor has asked us to create a program where we create lines of at least for integers and if the program registers there being four of the same integer horizontally, vertically, or diagonally it returns true. For example:

1 1 1 1 1 2 3 4 1 2 3 4
4 3 6 2 2 1 4 5 1 5 6 7
8 2 0 3 3 2 1 6 1 3 5 7
4 7 9 3 5 7 4 1 1 8 9 0

If the program doesn't see four integers of the same value anywhere, it is supposed to return false. I've got it so it returns true for the lines above, 6x6 lines of integers and lines where only four out of six+ integers are equal. However, I cannot get my code to return false if there are only three matching integers in a row/column/diagonal nor can I get the program to print out either true or false for lines that do not start at the top left corner. (i.e 2 3 1 1 1 1) For the former I get this error message:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 4
at ConnectFour.is4Consecutive(ConnectFour.java:41)
at ConnectFour.main(ConnectFour.java:32)

For the latter:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 6
at ConnectFour.is4Consecutive(ConnectFour.java:43)
at ConnectFour.main(ConnectFour.java:34)

The answer to fixing my code is probably something small or something that will make me wonder why I hadn't thought of it myself... Here is my code:

import java.util.Scanner;
public class ConnectFour {
private static Scanner sc;
public static void main(String[] args)
{
sc = new Scanner(System.in);
System.out.print("Enter the height: ");
int h = sc.nextInt();
System.out.print("Enter the width: ");
