在“运行窗口”中调用命令

Question

Opening the Run window (Windows + r) and running a command -> I want to trigger this same command using Java. I tried this using :

Runtime.getRuntime().exec(command);

But this did not worked. Please let me know how to achieve this.

Answer 1

Can you try this:

ProcessBuilder pb=new ProcessBuilder("explorer");
        pb.redirectErrorStream(true);
        Process process=pb.start();
        BufferedReader inStreamReader = new BufferedReader(
            new InputStreamReader(process.getInputStream())); 

        while(inStreamReader.readLine() != null){
            //do something with commandline output.
        }

Answer 2

Use this command:

Runtime.getRuntime().exec(new String[] {"cmd.exe", "/c", "start", "winword"});

This successfully runs Microsoft word ( winword ), which is not runnable directly through cmd. The start command behaves the same as run does.

Add parameters afterwards like this:

Runtime.getRuntime().exec(new String[] {"cmd.exe", "/c", "start", "winword", "C:\\Example.docx"});
