How to open a file with a specific programme in Desktop

I am using java.awt.Desktop to open a file. I don't have control over the filetype programme associations and I would like to open a file with a specific programme that is non default. How can I do this?

This is my code:

public static void open(File document) throws IOException {
Desktop dt = Desktop.getDesktop();;

If you know the name and location of the program to execute, you can run it directly, and provide it with the filename to open as an argument (after a space):

try {
    Runtime runTime = Runtime.getRuntime();
    // Don't forget that '\' needs to be escaped with another '\'
    Process process = runTime.exec("C:\\Windows\\system32\\notepad.exe" +
                                   " " +    // Separate argument with space
} // try
catch (IOException e) {
} // catch
