Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    Preferences prefs = Preferences.userNodeForPackage(String.class);

    // Save some values
    prefs.put("myString", "a string"); // String
    prefs.putBoolean("myBoolean", true); // boolean
    prefs.putInt("myInt", 123); // int
    prefs.putLong("myLong", 123L); // long
    prefs.putFloat("myFloat", 12.3F); // float
    prefs.putDouble("myDouble", 12.3); // double
    byte[] bytes = new byte[10];
    prefs.putByteArray("myByteArray", bytes); // byte[]

    // Export the node to a file
