Enhanced for loop cannot assign values to arrays (Java)

See the English answer > why Java foreach doesn't change element value? 7

int[] array = new int[5];
    for(int i = 0; i < 5; i++)
      array[i] = 10;

Produce what I want But why doesn't this fit "for everyone":

for(int element : array)
      element = 10;

Is there a specific reason for this or what I did wrong?

Solution

In the enhanced for loop element, it is a local variable that contains a reference to the current element of the array (or the value in the basic case) or iterative iteratable

Assigning to it does not affect the array / iteratable

It is equivalent to:

int[] array = new int[5];
for(int i = 0; i < 5; i++) {
  int element = array[i];
  element = 10;
}

The array will not be modified

If you need to modify the array, use the regular for loop
