Read/write to Windows registry using Java

Question

How is it possible to read/write to the Windows registry using Java?

Answer 1

I prefer using java.util.prefs.Preferences class.

A simple example would be

// Write Operation
Preferences p = Preferences.userRoot();
p.put("key","value"); 
// also there are various other methods such as putByteArray(), putDouble() etc.
p.flush();
//Read Operation
Preferences p = Preferences.userRoot();
String value = p.get("key");
