Storing properties in XML file

     

This Example shows you how Store properties in a new XML File. JAXP (Java API for XML Processing) is an interface which provides parsing of xml documents. Document BuilderFactory is used to create new DOM parsers. These are some of the methods used in code given below for storing properties in xml file:-

File f=new File("2.xml"):-Creating File in which properties are to be Stored.

Properties p=new Properties():-Creates an instance of class Property class .Importance of property class here is that by the use of this class we can save properties to a stream and also load properties from a stream.

p.setProperty("Girish", "roseindia"):-This method returns the previous value of the specified key in the property list. Here "Girish" is the key that is to be placed into the property List. "roseindia" is the value corresponding to the key "Girish".
