所有已实现的接口:
Serializable, Comparable<ByteString>
public class ByteString extends Object implements Serializable, Comparable<ByteString>
An immutable sequence of bytes.

Byte strings compare lexicographically as a sequence of unsigned bytes. That is, the byte string ff sorts after 00. This is counter to the sort order of the corresponding bytes, where -1 sorts before 0.

Full disclosure: this class provides untrusted input and output streams with raw access to the underlying byte array. A hostile stream implementation could keep a reference to the mutable byte string, violating the immutable guarantee of this class. For this reason a byte string's immutability guarantee cannot be relied upon for security in applets and other environments that run both trusted and untrusted code in the same process.
