Syntax meaning in enhanced for loop (java)

Question

I tried to solve this case but have no clues.
int[] arr= {1,2,3,4,4};
for (x: arr) {
arr[x]= 0; }
// doest it mean that every values in arr will be replaced with 0? thanks.

Answer 1

yes

Answer 2

Nah, if you print that array the result would be 0 0 3 0 0. This is where i got stuck.

Answer 3

Oh, really? In other langs that means everything is 0.
