Question

I'm having trouble writing my program in java, the issue is in my method called booleanArryayToString that takes a 2D Boolean array as input and returns a string;

for this method it is assumed that the Boolean true is represented by the Char 'x';

and that the Boolean false is represented by the Char "."

static String booleanArryayToString(boolean[][] panel{

return "replace"

}

for example if Boolean[][] panel = {{f,f,t,t,t,f,f,},{f,t,t,f,t,t,f,}}

it well return: ..xxx...xx.xx.

public class BooleanArrayToString {

    static String booleanArrayToString(boolean[][] panel) {
        String result = "";
        for (int i = 0; i < panel.length; i++) {
            for (int j = 0; j < panel[i].length; j++) {
                if (panel[i][j]) {
                    result += 'x';
                } else {
                    result += '.';
                }
            }
        }
        return result;
    }

    public static void main(String[] args) {
        boolean[][] panel = {{false, false, true, true, true, false, false,}, {false, true, true, false, true, true, false,}};

        System.out.println(booleanArrayToString(panel));
    }
}
