How to open any command line program through a swing GUI and pass commands to it?

由 …衆ロ難τιáo~ 提交于 2019-12-08 09:27:18
问题 I basically want to convert a command line program into a gui program using Swing. As soon as the user presses an appropriate button, a corresponding command should be passed by the GUI to the command line program. If we can do this without showing the command line program then it would be a complete replacement of that program. I have been trying to search this on the internet for the past two days now and I only found the Runtime.getRuntime().exec(cmd) command useful to open the command

What's the best way to send commands through TCP Sockets?

由 倾然丶 夕夏残阳落幕 提交于 2019-12-08 07:58:17
问题 What I'm currently doing with my Server and Client is sending commands between them using simple strings to bytes. What it comes down to is basically this (to send a message to the server as an example): byte[] outStream = System.Text.Encoding.UTF8.GetBytes("$msg:Test Message"); serverStream.Write(outStream, 0, outStream.Length); And the recieving end encodes back to a string. It recognizes the command by doing this: recievedstring.Split(':')[0] and assuming that recievedstring.Split(':')[1]
