Arrays.fill with multidimensional array in Java

Question

How can I fill a multidimensional array in Java without using a loop? I\'ve tried:

double[][] arr = new double[20][4];
Arrays.fill(arr, 0);

Answer 1

public static Object[] fillArray(Object[] arr,Object item){
    Arrays.fill(arr, item);
    return arr;
}
Character[][] maze = new Character[10][10];
    fillArray(maze, fillArray(maze[0], '?'));

    for(int i = 0;i<10;i++){
        System.out.println();
        for(int j = 0;j<10;j++){
            System.out.print(maze[i][j]);
        }
    }

i hope this do well
