Java object serialization a tool class saved as an XML file

Java Object |xml

Today I looked at the Java.beans bag and found two good things, Xmlencoder and Xmldecoder. It's hard to find yourself accessing objects from XML before. Do the gadget class, you can use it later.

Package com.imct.util;

Import Java.beans.XMLDecoder;
Import Java.beans.XMLEncoder;
Import Java.io.File;
Import Java.io.FileInputStream;
Import java.io.FileNotFoundException;
Import Java.io.FileOutputStream;
Import java.io.IOException;
Import java.util.ArrayList;
Import java.util.List;
