Question

Write Java code to create a 2D array that mimics the one below. Do not use curly brackets to assign values. Instead, use nested loops and if-else or switch.

x	o	o	o	x
o	x	o	x	o
o	o	z	o	o
o	x	o	x	o
x	o	o	o	x

Answer 1

public class TwoDArray {

    public static void main(String[] args) {
        char[][] data = new char[5][5];
        for (int i = 0; i < data.length; i++) {
            for (int j = 0; j < data[i].length; j++) {
                if (i == 2 && j == 2) {
                    data[i][j] = 'z';
                } else if (i == j || i == 4-j) {
                    data[i][j] = 'x';
                } else {
                    data[i][j] = 'o';
                }
            }
        }
        // print array
        for (int i = 0; i < data.length; i++) {
            for (int j = 0; j < data[i].length; j++) {
                System.out.print(data[i][j] + " ");
            }
            System.out.println();
        }
    }
}
