Java API call to get a String of certain length made of spaces.
Arrays have .length, Strings have length()
Lists have size()
Map has containsKey(T key), get(T key)
Digit character (‘0’ – ‘9’) to its int value (int)c – 48 (‘0’ is 48, ‘9’ is 57, ‘A’ is 65)
LinkedList API (add(), iterate)
List<Key>[] a; a = new List<Key>[10];
The mathematics of a modulo of a negative number.
