Since java.util.Properties is based on java.util.Hashtable, you can get an enumeration over all of the property names with:
Enumeration e = myProp.keys();
// or the easy to remember:
Enumeration e = myProp.propertyNames() ;
A Properties can list to a PrintStream like this:
myProp.list( System.out ) ; // a nice readable format
You can also save a Properites object to a file
with the store() method
A good reference such as Java in a Nutshell and/or copy of the JavaDocs is your friend.
