从套接字读取n秒

Question

I'd like to put a timeout reading a socket, i found this in C++ and i'd like to convert it on Java.

int readable_timeo(SOCKET fd, int sec){
fd_set rset;
struct timeval tv;


FD_ZERO(&rset);
FD_SET(fd, &rset);

tv.tv_sec = sec;
tv.tv_usec = 500000;

return (select(0, &rset, NULL, NULL, &tv));}

Any suggestion?

Thanks for the help!

Answer 1

The simple equivalent in Java is Socket.setSoTimeout(). The equivalent of the code you posted, which isn't the simplest, is Selector.select().
