Iterating Through Properties Loaded from LoadedFromXML Method

Question

For the first time, I am storing and retrieving application settings from properties files using Java 1.5. What I am looking for is the simplest way to iterate through the key/value pairs and print them out.
Any recommendation on the best way to accomplish this?

Answer 1

So you have a Properties object, and you want to
print the properties in it? Well, it doesn't make any
difference whether it was loaded from XML or
key-value pairs or Java code or whatever. Simplest
way (which you asked for before asking for best way)
is by calling its store(OutputStream) method.In the following code, I have an xml formatted configuration file that is loaded into a properties object ( prop ) , the properties are enumerated ( Enumeration ) , and finally the list of properties is looped through with the property name and its value printed out. This should help you out.
          try {
               fis = new FileInputStream( ftpConfigFile );
               prop.loadFromXML(fis);
               Enumeration e = prop.propertyNames();
               while ( e.hasMoreElements()) {
                    String elem = ( String )e.nextElement();
                    myLogger.debug( elem + "=" + prop.getProperty(elem)) ;
          catch ( NullPointerException e) {
               myLogger.error( "Error encountered " + e.getMessage() );
               return false;
          catch ( IOException e ) {
               myLogger.error( "Error encountered " + e.getMessage() );
               return false;
          finally  {
               try {
                    fis.close();
               catch ( Exception e){
          }
