Java: Multiple Classes and Arrays

I am currently in a Java course this semester (completely new to programming and struggling a bit with multiple classes and arrays). The current program I am working on is a Sudoku type game using a 2D array. The instructors have given us a class for Constant numbers in this array (the initial values in the Sudoku puzzle). Here is the code for it.

public class Constants {
 public static int game[][] = new int[][] {
{ 1, 2, -1, -1, -1, -1, -1, -1, 8 },
{ -1, -1, 4, -1, 8, -1, 7, 1, -1 },
{ -1, -1, -1, -1, 1, -1, 5, 3, -1 },
{ 8, -1, -1, -1, -1, 4, -1, -1, -1 },
{ -1, 4, -1, -1, -1, -1, 6, 5, -1 },
{ 7, 5, -1, 1, -1, -1, -1, -1, -1 },
{ -1, 7, -1, -1, -1, -1, -1, 9, -1 },
{ 3, -1, 1, 8, 5, -1, -1, -1, 6 },
{ 5, 6, -1, 9, -1, 7, -1, -1, -1 } 
};

The values of -1 refer to blank spaces in the puzzle.

Basically all I need to know is.. how would I access this array or these values in my other Class and main method? Once again I apologize for being completely new to java, thank you in advance.

You would access the actual game variable with 

Constants.game

and you can access individual members of the array with 

Constants.game[i][j]

where i is the row and j is the column of the element you are trying to access.
