The easiest way to transform collection to array?

Question

Suppose we have a Collection. What is the best (shortest in LoC in current context) way to transform it to Foo[]? Any well-known

Answer 1

For the original see doublep answer:

Foo[] a = x.toArray(new Foo[x.size()]);

As for the update:

int i = 0;
Bar[] bars = new Bar[fooCollection.size()];
for( Foo foo : fooCollection ) { // where fooCollection is Collection
    bars[i++] = new Bar(foo);
}
