Flyweight Objects (Character):?

Short answer: The Character class holds the intrinsic state (the character symbol), which is shared across all instances. This makes it an ideal candidate for the Flyweight Pattern because multiple characters (e.g., 'H', 'e', 'l') may appear many times in the same text, but they only need one Character object for the symbol.
