Deep copying a 2d array in Java

0 votes

Can someone guide me how to perform a deep copy of a boolean[][] array? I tried using .clone() on my 2d boolean array but it was a fail.

Any suggestions are welcomed.

I guess, for deep copying you will have to iterate over your 2 dimensional array. You can refer the following code for the same:

public static boolean[][] deepCopy(boolean[][] org) {
    if (org == null) {
        return null;
    }

    final boolean[][] res = new boolean[org.length][];
    for (int i = 0; i < org.length; i++) {
        res[i] = Arrays.copyOf(org[i], org[i].length);
     }
    return res;
}

Hope it helps!!

If not then its recommended to join our Java training class and learn about Java in detail.

Thank You!!
