Question

I have a working file rename java tool, now I want to add an if condition to run a commandline command if I checked a box as part of the rename process on each file it renames.

I will be changing the dos code later, but its a sample I found that works. Part of my problem is my filerename is its own class, so I will also need to figure out how to combine this class or reference the dos command somehow from my main rename class.

update

I updated the code with the changes from the answer, but the commandline command does not work and it crashes java with no error. The command does work from cmd line.

import java.io.IOException;
import java.io.InputStream;

public class doscommandrun {
     public static void run() {  
         final String dosCommand = "cmd converter.exe file.doc -android -o file.txt";
            try {
                final Process process = Runtime.getRuntime().exec(
                        dosCommand + " ");
                final InputStream in = process.getInputStream();
                int ch;
                    while((ch = in.read()) != -1) {
                        System.out.print((char)ch);
                    }
                    } catch (IOException e) {
                        e.printStackTrace();
            }
        }
    }

Answer 1

I add /c after the cmd in my renametool class

I am still having issues but wither a different problem.
