2D Array, output is no where near correct

Question

import java.util.Scanner;

public class Maze {

    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);

        int rows = 0;
        int cols = 0;
        String arrayLine = "";
        int counter = 0;

        rows = sc.nextInt();
        cols = sc.nextInt();
        arrayLine = sc.next();

        char[][] array = new char[rows][cols];

        for(int r=0; r<rows; r++){
            for (int c=0; c<cols; c++){
                array[r][c] = arrayLine.charAt(counter);
                counter ++;
            }
        }

        System.out.println(array);
        System.out.println();
    }
}

The output I'm getting it when i run it is [[C@252f0999

Help please, I'm just starting to learn java!

Answer 1

array is a special kind of object, it doesn't have an implicit toString() which manages pretty printing of the content of the array, what happens is that the object is represented by the standard representation for objects which is its hashcode.

You should use Arrays.toString():

for (int i = 0; i < array.length; ++i)
  System.out.println(Arrays.toString(array[i]));

Mind that you can't directly write Arrays.toString(array) because, as stated in documentation:

If the array contains other arrays as elements, they are converted to strings by the Object.toString() method inherited from Object, which describes their identities rather than their contents.

Answer 2

When you call println() on an object, Java returns the location of the resource by default (that's what C@252.... is). You want to call

System.out.println(Arrays.deepToString(array) 

to display the data in the array.
