책에서 2차원 배열 삼목 코딩을 그대로 적어서 실행하는데 오류가 나네요 그런데 이유를 못찾겠습니다.
import java.util.*;
public class Coderunner {
public static void main(String[]args){
char[][] board = new char[3][3];
int x,y;
Scanner scan = new Scanner(System.in);

}
}
do{

"1 " + board[i][2]);
if(i != 2)
System.out.println("---1---1---");
}
System.out.print("insert your next coordinates");
x = scan.nextint();

continue;
