It is so easy with Java! Is Java the better Way?

B4X:
try
    {
    Socket sock = new Socket("192.168.1.222", 9100);
    PrintWriter oStream = new PrintWriter(sock.getOutputStream());
        oStream.println("HI,test from Android Device");
        oStream.println("\n\n\n");
        oStream.close();
        sock.close();
    }
    catch (UnknownHostException e)
    {
        e.printStackTrace();
    }
    catch (IOException e)
    {
        e.printStackTrace();
    }
