????????:
Closeable, AutoCloseable, Readable

public class TeeReader extends ProxyReader
Reader proxy that transparently writes a copy of all characters read from the proxied reader to a given Reader. Using ProxyReader.skip(long) or ProxyReader.mark(int)/ProxyReader.reset() on the reader will result on some characters from the reader being skipped or duplicated in the writer.

The proxied reader is closed when the close() method is called on this proxy. You may configure whether the reader closes the writer.
