Filling 2D Array

[Nakira]

Hi all, I'm having a little trouble getting my head around

static void fill(char[] a, char val)]

I'm not entirely sure what its telling me to do.
This is the section of code containing this:

public static class Grid
	{
		Grid[][] twoDimGrid = new Grid[31][31]; // 31x31 grid
		private static void fill(char[] twoDimGrid, char ' ');
		void print(){System.out.println(this.twoDimGrid);}
	}

From what i've gather i type "char[]" then the name of array im filling "twoDimGrid" then i use a comma and enter char val. So i type "char ' '" However i get errors on eclipse saying:

Syntax error on token "' '", invalid VariableDeclaratorld

I have no idea what this means, if i cant use a space as a char what else should i use for my grid?

i managed to get it t compile with no errors, however it does not display the array, any ideas why?

//define SnakeGame class
public class SnakeGame
{
	char s = ' ';
	//create main method(All Java prgrams need one to run ;))
	public static void main(String[] args)
	{
		
	}
	//Create a 2D grid for the game to be played on
	public static class Grid
	{
		Grid[][] grid = new Grid[31][31]; // 31x31 grid
		static void fill(char grid[][], char _){}
		void print(){System.out.println(this.grid);}
	}
	
}

It goes something like this.I'm not proficient on the enhanced for loop, probably have one or more blunders but it is something like this.

// preliminary
public class SnakeGame
{
    //create main method(All Java prgrams need one to run ;))
    public static void main(String[] args)
    {
        Grid grid = new Grid();
        grid.fill();//
        grid.print();//
    }
    //Create a 2D grid for the game to be played on
    public class Grid
    {
        char s = ' ';
        char [][] grid = new char[31][31]; // 31x31 grid
        void fill()
        {
            for( char[] row : grid )
            {
                for( char row : column )
                {
                    column = s;
                }
            }
        }
        void print()
        {
            for( char[] row : grid )
            {
                for( char row : column )
                {
                    System.out.println(column);
                }
            }
        }
    }
}

A massive thanks for this, i can see where your coming from now and I'm beginning to understand it better, however that code produced 7 errors. :s

i would try and sort them but i dont understand. :s
