I'm a student trying to figure out how to fix a seemingly simple problem. I keep getting an error while trying to initialize 2 variables in a FOR loop. I'm trying to create rows for a game board. Why am I getting this error? 

This is the method: 

```
public String [] board;

public void printBoard(){
            for(int i, j = 0; i < this.board.length; i++, j++)
                if(j > 10)
                    System.out.println();
                else
                    System.out.print(this.board[i]);

> java:39: error: variable i might not have been initialized

```
