The declared size in for-each
is always less than the size of the array.why ?
int[][][] c = {{{1,2,3}}};
for(int [][] z : c )
//code
c is a 3D array so should z, right? like:
int[][][] c = {{{1,2,3}}};
for (int[][][] z : c) // which is syntactically wrong
//code
Thank you in advance.
The answer as I understand it from the comments and the below answer: the declaration inside for-each
in the 3D array for-each
considers every 2D array as an element,
in the 2D array for-each
considers every 1D array as an element and so on..
in the 1D array it takes the elements of the array directly as elements.
Read that construct as the for-each
loop. In this case, for each int[][]
in the int[][][]
. Another example, for-each
int
in an int[]
.
int[] arr = {1,2,3};
for (int i : arr) {
System.out.println(i);
}
