Static utility class for Base64 encoding/decoding a byte array or
Serializable object with support for compression and escaped HTTP
strings using a variant of Base64 encoding.
This class encodes characters using a variant of Base64 encoding that results
in an encoded string that doesn't need to be escaped for use in HTTP URLs.
A complement to java.util.StringTokenizer that provides
tokenizing by substrings instead of single characters as well as static
utility methods for standard tasks.
This class is semantically compatible with StringTokenizer.
ThreadPool is a generic thread pool that manages and recycles threads instead
of creating them everytime some task needs to be run on a different thread.
Thread pooling saves the virtual machine the work of creating brand new
threads for every short-lived task.
