(请教)java中socket 默认超时时间是？

java中socket 默认超时时间是多久？
是50秒吗？

晕，从JAVA转到新手版，怎么还是没有人告诉我呢？
这是我前天在一家公司的面试题，我当时回答的是60秒。
但是google和百度都还找不到答案，唯一有个地方说50秒。
这是属于TCP/IP里面的东西吗？

MS:永远吧

connect

public void connect(SocketAddress endpoint,
                    int timeout)
             throws IOException

    Connects this socket to the server with a specified timeout value. 
    A timeout of zero is interpreted as an infinite timeout.
    The connection will then block until established or an error occurs.

    Parameters:
        endpoint - the SocketAddress
        timeout - the timeout value to be used in milliseconds. 
    Throws:
        IOException - if an error occurs during the connection 
        SocketTimeoutException - if timeout expires before connecting 
        IllegalBlockingModeException - 
        if this socket has an associated channel, and the channel is in non-blocking mode 
        IllegalArgumentException - 
        if endpoint is null or is a SocketAddress subclass not supported by this socket
    Since:
        1.4

选自java API :java.net.Socket

嗯，超时时间是可以设置的，但是缺省的超时时间是多少呢？

A timeout of zero is interpreted as an infinite timeout.

不是写了么，这就是缺省。

呵呵，我感觉这里说理论的比较多，真的碰到点问题，javaeye未必是最好的选择。

getSoTimeout()
