Please see my answer to a similar question which some people found useful. Here is it:
You can use Runtime.exec(java.lang.String, java.lang.String[], java.io.File) where you can set the working directory.
Or else you can use ProcessBuilder as follows:
ProcessBuilder pb = new ProcessBuilder("myCommand", "myArg1", "myArg2");
pb.directory(new File("myDir"));
Process p = pb.start();
You can use ProcessBuilder class as follows:
public static void main(String [] args) throws IOException
{
String[] command = {"CMD", "/C", "dir"};
// ProcessBuilder will execute process named 'CMD' and will provide '/C' and 'dir' as command line arguments to 'CMD'
ProcessBuilder pbuilder = new ProcessBuilder(command);
Process process = probuilder.start();
//Wait for process to finish
try
{
int exitValue = process.waitFor();
System.out.println("\n\nExit Value is " + exitValue);
}
catch (InterruptedException e)
{
e.printStackTrace();
}
}
{"CMD", "/C", "dir"}. Does cmd stands for command, /C denotes C directory and dir means any directory in the C ?
If you want to change working directory there are built in functions for that. If you want to run commands, see example
This is used to run commmand line commands using Java
Runtime.getRuntime().exec()
