How to find fixed width fonts?

Question

Hi! I want to retrieve a list of all available fixed width fonts (e.g. Monospaced) on the user's system.
I tried the GraphicsEnvironment() class and stepped through the result of getAllFonts(). I compared the widths of the chars per font if they differ... No success. Some fonts are filtered but not all.
On windows systems you can get a font metrics info with a type like 'Symbol', 'Fixed', 'Non fixed' etc.
Is there something comparable in Java?
Thanks in advance,
Jan

Here's some code based on jsalonen's suggestion. It prints the font if M and i are the same width.
   public static void main(String[] args) {
      GraphicsEnvironment ge=GraphicsEnvironment.getLocalGraphicsEnvironment();
      Font[] s=ge.getAllFonts();
      Canvas comp=new Canvas();
      for(int i=0;i<s.length;i++) {
         int f1=comp.getFontMetrics(s).charWidth('i');
int f2=comp.getFontMetrics(s[i]).charWidth('M');
if(f1==f2) System.out.println(s[i].getName());
