MagicValue - Code Won't Display Invalid Methods

import java.util.Scanner;
public class Magic
{
public static void main ( String args[] )
{
Scanner in = new Scanner (System.in);
int[][] square = new int [4][4];
int sqlength = square.length;
int magicValue = sqlength * (sqlength * sqlength + 1) / 2;

[Code] ....

Here is what the output should look like.

Please enter the 4 values for row 0, separated by spaces: 1 2 3 4
Please enter the 4 values for row 1, separated by spaces: 5 6 7 8
Please enter the 4 values for row 2, separated by spaces: 9 10 11 12
Please enter the 4 values for row 3, separated by spaces: 13 14 15 16

Checking square for problems:

DIAG: VALID
ROWS: 0 1 2 3
COLS: 0 1 2 3
RANG: VALID
MAGIC: NO

Using my program it prints

DIAG: VALID
RANG: VALID
MAGIC: NO
