For each loop: can we populate an array?

Question

I can read data from an array with for each syntax:

int[] a = new int[100];
for (int i = 0; i < 100; i++){
    a[i] = i;
}


for (int element : a){
    System.out.println(element);                         
}

But is it possible to populate the array likewise. Say, with i*2 values?
I failed to invent such a method and would rather ask you whether I'm wrong or not.

From Java Docs,

The for-each loop hides the iterator, so you cannot call remove. Therefore, the for-eachloop is not usable for filtering. Similarly it is not usable for loops where you need to replace elements in a list or array as you traverse it. Finally, it is not usable for loops that must iterate over multiple collections in parallel. These shortcomings were known by the designers, who made a conscious decision to go with a clean, simple construct that wouldcover the great majority of cases.

So, in simple words, its not possible to populate arrays.
