java swing fonts uimanager

I was wondering how to set the default font for my entire Java swing program. From my research it appears it can be done with UIManager, something to do with LookAndFeel, but I can't find specifically how to do it, and the UIManager appears pretty complicated.

try:

public static void setUIFont (javax.swing.plaf.FontUIResource f){
    java.util.Enumeration keys = UIManager.getDefaults().keys();
    while (keys.hasMoreElements()) {
      Object key = keys.nextElement();
      Object value = UIManager.get (key);
      if (value instanceof javax.swing.plaf.FontUIResource)
        UIManager.put (key, f);
      }
    }

Call by ...

setUIFont (new javax.swing.plaf.FontUIResource("Serif",Font.ITALIC,12));
