Java to determine whether IP, port can be connected

1. Determine if IP, port can be connected

public static Boolean ishostconnectable (String host, int port) {SOCKET socket = new socket (); try {socket.connect (new inets Ocketaddress (host, Port));} catch (IOException e) {e.printstacktrace (); return false;} finally {try {socket.close ()} catch (IOException e) {e.printst Acktrace ();}} return true;}

2. Determine if IP can connect to timeout is the timeout period

public static Boolean ishostreachable (String host, Integer TimeOut) {try {return Inetaddress.getbyname (host). Isreachable (TimeOut);} catch (Unknownhostexception e) {e.printstacktrace ();} catch (IOException e) {e.printstacktrace ();} return false;}
