How to handle spaces in using path to the file

Question

Hi Friends,
I am getting error "file not found" if I give path of the file that contains spaces in it. (eg. C:\Users\Sample Project\file.txt)
If I give path that doesn't contain spaces (eg. C:\Users\Sample\file.txt) then it works fine without any error.
Basically I am invoking one command at runtime (using "exec") in my java program that excepts path of the file as one parameter.
I can't remove space by manipulating path - othewise that path will be different.
How can I solve this issue?
Thanks

Works for me:
import java.io.*;
public class ProcessExample {
    public static void main(String[] args) throws IOException {
        if (args.length == 0) {
            Runtime r = Runtime.getRuntime();
            dump(r.exec("java ProcessExample foo \"bar baz\""));
        } else {
            for(String s : args) {
                System.out.println(s);
    static void dump(Process p) throws IOException {
        BufferedReader r = new BufferedReader(new InputStreamReader(p.getInputStream()));
        for(String s; (s = r.readLine()) != null; ) {
            System.out.println("[" + s + "]");
}But ejp's advice is even better.
