Separately, claims of O(1) have another assumption (normally correctly) that...
Understanding recursion [closed]
.... We'll use a binary tree of nodes, but this time the value held will be a character, not a number.
Our tree will have a special property, that for any node, its character comes after (in alphabetical order) the character held by its left child and before (in alphabetical order) the character held ...

Taking advantage of the object oriented nature of Java when you write a collection class it can store any object so...

In all other cases (byte, short, char), you need the cast as there is no specific suffix.
The Java spec allows both upper and lower case suffixes, but the upper case version for longs is preferred, as the upper case L is less easy to confuse with a numeral ...
