How to Execute Windows Commands Using Java - Change Network Settings
Runtime.getRuntime().exec("netsh");See Runtime Javadoc.
EDIT: A later answer by leet suggests that this process is now deprecated. However, as per the comment by DJViking, this appears not to be the case: Java 8 documentation. The method is not deprecated.
Use ProcessBuilder
ProcessBuilder pb=new ProcessBuilder(command);pb.redirectErrorStream(true);Process process=pb.start();BufferedReader inStreamReader = new BufferedReader( new InputStreamReader(process.getInputStream())); while(inStreamReader.readLine() != null){ //do something with commandline output.}
You can run the command with Runtime.getRuntime().exec("<command>") (eg. Runtime.getRuntime().exec("tree")). But, this will only run executables found in path, not commands like echo, del, ... But only stuff like tree.com, netstat.com, ... To run regular commands, you will have to put cmd /c before the command (eg Runtime.getRuntime().exec("cmd /c echo echo"))
