java.util.prefs包。一个简单的例子：

// Retrieve the user preference node for the package com.mycompany

Preferences prefs = Preferences.userNodeForPackage(com.mycompany.MyClass.class);

// Preference key name

final String PREF_NAME = "name_of_preference";

// Set the value of the preference

String newValue = "a string";

prefs.put(PREF_NAME, newValue);

// Get the value of the preference;

// default value is returned if the preference does not exist

String defaultValue = "default string";

String propertyValue = prefs.get(PREF_NAME, defaultValue); // "a string"
