Java Programming

Hi all,

Firstly, I am NOT posting a question, but contributing a solution since I had this problem, which haunted me for sometime, and finally solved it.
I haven't seen (far as I could search) any solution here, so here it is!

When you do:

Runtime.getRuntime().exec("cmd /c start C:\myDir\files\myFile.doc");

I see everyone agree it works. It doesn't contain any spaces in the path.
When something like:

Runtime.getRuntime().exec("cmd /c start C:\my Dir\files\my File.doc");

this now breaks.

There had been number of suggestions around, but none worked for me.

Let me just post the code first, and explain later.

    /**
     * Inserts quotes at correct locations in nominated path string.
     */
    public static String putQuotesAroundSpaces(String originalPath) {
    	
    	StringTokenizer st = new StringTokenizer(originalPath, File.separator);
    	String newPath = "";
    	while(st.hasMoreTokens()) {
    		String token = st.nextToken();
    		if (token.contains(" ")) {
    			newPath += File.separator + "\"" + token + "\"";
    		} else {
    			newPath += File.separator + token;
    		}
    	}
    	return newPath.substring(1, newPath.length());
    }

And do this:

Runtime.getRuntime().exec("cmd /c start " + putQuotesAroundSpaces(yourFile));

What's happening is that quotes are inserted at various places:

    cmd /c start C:\"my Dir"\files\"my File.doc"

Please note that it is required to quote names with spaces only.
Not the whole path.
So there your go. Hope this will help others who's going/gone through the same nightmare I had!

Happy Java programming! :)
