Question

I have a two dimensional array

 public class TwoDimensions {

public static void main(String[] args){
    String[][] names = new String[3][3]; 
        names[0][0] = "Joe";
        names[1][1] = "Jane";
        names[2][2] = "Herkimer";
    for(String[] output:names){
        System.out.println(names);
    }
    }
}

How can I print all of its content. For location [0][1] I have nothing. So it should print null or something.

Answer 1

If you want to print this as a grid you can use

for (String[] row : names)
    System.out.println(Arrays.toString(row));

prints

[Joe, null, null]
[null, Jane, null]
[null, null, Herkimer]
