public interface CharSequence
Known Indirect Subclasses

A CharSequence is a readable sequence of char values. This interface provides uniform, read-only access to many different kinds of char sequences. A char value represents a character in the Basic Multilingual Plane (BMP) or a surrogate. Refer to Unicode Character Representation for details.

This interface does not refine the general contracts of the equals and hashCode methods. The result of comparing two objects that implement CharSequence is therefore, in general, undefined. Each object may be implemented by a different class, and there is no guarantee that each class will be capable of testing its instances for equality with those of the other. It is therefore inappropriate to use arbitrary CharSequence instances as elements in a set or as keys in a map.

Public Method Summary

Returns a stream of code point values from this sequence.
abstract int
Returns the length of this character sequence.
abstract CharSequence
subSequence(int start, int end)
Returns a new CharSequence that is a subsequence of this sequence.
abstract String
