Can `IndexOutOfBoundsException` be really thrown? We don't have any index here.
From the implementation I see that only `OutOfMemoryError` and
`IllegalArgumentException` can be thrown.
Also, I see a small descrepancy between messages in this method and
`String.repeat`. The latter has:
* @throws IllegalArgumentException if the {@code count} is
* negative.
*
* @since 11
*/
public String repeat(int count) {
if (count < 0) {
throw new IllegalArgumentException("count is negative: " + count);
}
Probably it's better to reuse the same wording ("is negative" instead of "is
less than zero") for consistency?
