Solution
In this example, the XMLEncoder object is used to encode the Settings object,
which contains program settings information and writes it to the settings.xml file.
The XMLDecoder takes the settings.xml file and reads it as a stream, decoding
the Settings object. A FileSystem is used to gain access to the machine's file
system; FileOutputStream is used to write a file to the system; and FileIn-
putStream is used to obtain input bytes from a file within the file system. In this ex-
ample, these three file objects are used to create new XML files, as well as read them
for processing.
//Encoding
FileSystem fileSystem = FileSystems.getDefault();
try (FileOutputStream fos = new
FileOutputStream("settings.xml"); XMLEncoder encoder =
new XMLEncoder(fos)) {
encoder.setExceptionListener((Exception e) -> {
System.out.println("Exception! :"+e.toString());
});
encoder.writeObject(settings);
}
// Decoding
try (FileInputStream fis = new
FileInputStream("settings.xml"); XMLDecoder decoder =
new XMLDecoder(fis)) {
ProgramSettings decodedSettings = (ProgramSettings)
decoder.readObject();
System.out.println("Is same?
"+settings.equals(decodedSettings));
}
Path file= fileSystem.getPath("settings.xml");
List<String> xmlLines = Files.readAllLines(file,
Charset.defaultCharset());
xmlLines.stream().forEach((line) -> {
System.out.println(line);
});
