Socket

declaration

public class Socket implements Closeable

A TCP client connection: connect, then read/write its streams. Production rule: connect and read timeouts on every socket, no exceptions.

Key methods

`void connect(SocketAddress endpoint, int timeoutMs)`	Bounded connection attempt.
`void setSoTimeout(int timeoutMs)`	Bound each read — otherwise a silent peer hangs you forever.
`InputStream getInputStream() / OutputStream getOutputStream()`	The byte streams.
