Working with Java and Files Tutorial Trail Read Write XML Files Random Access Files Like object serialization this is very easy and straight forward. Below is two examples of psuedo code for writing and then reading. This code merely shows the steps. We didn’t have to use the buffered streams. With small files you do not have to but with larger files it will speed up reading and writing. XMLEncoder Class //psuedo code does not run import java.beans.*; import java.io.*; public class SerializeToXML { public static void main(String args[]){ // an object, composition of objects or collection of objects AnObject anObject = new AnObject(); XMLEncoder encoder=null; try{ encoder=new XMLEncoder(new BufferedOutputStream(new FileOutputStream("objects.xml"))); }catch(FileNotFoundException fnfe){...
