How to add a timeout value when using Java's Runtime.exec()?

Question

I have a method I am using to execute a command on the local host. I\'d like to add a timeout parameter to the method so that if the command being called doesn\'t finish in

Answer 1

I know this is really old post; i needed some help with a similar project so I thought I might give some of my code that I worked and ones that work.

long current = System.currentTimeMillis();

ProcessBuilder pb  = new ProcessBuilder(arguments);
try{
    pb.redirectErrorStream(true);
    process = pb.start();
    int c ;
    while((c = process.getInputStream().read()) != -1 )
        if(System.currentTimeMillis() - current < timeOutMilli) 
            result += (char)c;
        else throw new Exception();
    return result.trim();
    }catch(Exception e){
        e.printStackTrace();
    }
    return result;

Hope this helps the future :D
