CharSequence

CharSequence is an interface that Strings, CharBuffers, StringBuilders and StringBufferss implement. You can think of it as a generalisation or abstraction of Strings to let you index to pick out any particular character in the String. In other words, whenever you see a method asking for a CharSequence parameter, you can feed it a String, StringBuilder, StringBuilder… as you choose.

You could also write your own classes that implemented CharSequence, say to let you use a raw char[].

In contrast CharacterIterator steps through the String char by char.
