※ 引述《scdog (just do it)》之铭言：
: 我用java写了一个tcp socket server
: 但是当client自行断线时,server却不知道client已经断线
: 还一直丢封包给client(我程式写成连线成功一直丢封包)
: 不知道socket有没有function能够判断对方已经断线
: 乾瞎!
有的
isConnected method or isClosed method
public boolean isConnected()

true if the socket successfuly connected to a server

public boolean isClosed()
