How to Use the xmlencoder and xmldecoder classes to save window objects in swing

The xmlencoder class is a complementary replacement of objectoutputstream and can be used to generate the text representation of the JavaBean. It is used in the same way as the binary representation used to create a serializable object using objectoutputstream.

The xmldecoder class is used to read XML documents created using xmlencoder. Its purpose is similar to objectinputstream. For example, you can use the followingCodeSegment to read the first object defined in XML format (written through the xmlencoder class:

In this example, create a jframe, use xmlencoder to save the jframe object to the XML file, read the saved XML file through the xmldecoder object, and display the jframe.
