Outputting elements of an array with Arrays.toString()

Question

I have used the code below to create and populate an array, however, when it comes to printing the array I do not get the result I expect while using the Arrays.toString() function.

Rather than printing

newArray: [2, 4, 6]
newArray: [8, 10, 12]
etc..

it prints

newArray: [[I@15db9742, [I@6d06d69c, [I@7852e922, [I@4e25154f]
newArray: [[I@15db9742, [I@6d06d69c, [I@7852e922, [I@4e25154f]
etc..

The code:

public static void main(String[] args) {
    int[][] newArray = new int[4][3];
    int number = 2;
    for (int rowCounter = 0; rowCounter < newArray.length; rowCounter++) {
        for (int colCounter = 0; colCounter < newArray[rowCounter].length; colCounter++) {
            newArray[rowCounter][colCounter] = number;
            number += 2;
        }
        System.out.println("newArray: " + Arrays.toString(newArray));
    }
}

Any help with this would be much appreciated.

Answer 1

You can use deepToString instead of toString:

System.out.println(Arrays.deepToString(newArray));

Answer 2

Try

Arrays.deepToString(newArray)
