enhanced 4 loop 4 2d array (mod. edit: enhanced for-loop for 2D array)

Hi all,


can an enhanced for loop be used for mulitdimensional array? if yes then can anyone kindly give me some example. I tried it on my side and it gave me error "incompatible types".

Thank you all

Don't use the digit '4' for the word 'for'. This is a technical forum, not a kindergarten school.

Clarified the title.

First show what you tried.

A multidimensional array is an array of arrays.

it is some like this

class Some

{

public static void main(String[] args)

{

int a[][] = {{1,2,3}, {1,2}};


for(int b: a)

{

System.out.println(b);

}

}

}

Now when i try to run this it throws incompatible error !

As Darryl wrote: a multi dimensional array is an array of arrays, so your enhanced for-loop iterates over one dimensional arrays:

Code:

---

for (int[] row : a) {
  for (int element : row) {
      ...
  }
}

kind regards,

thanks!!
