O codigo abaixo:
private void Salvar() {
Preferences prefsHora = Preferences.userNodeForPackage(getClass());
prefsHora.put(XmlPreferences.Mes, "03_2004");
prefsHora.put(XmlPreferences.DiaDoMes, "01");
prefsHora.put(XmlPreferences.EntradaManha, "08:00");
prefsHora.put(XmlPreferences.SaidaManha, "11:30");
prefsHora.put(XmlPreferences.EntradaTarde, "12:30");
prefsHora.put(XmlPreferences.SaidaTarde, "18:00");
System.out.println("Gravado
");
}
cria o seguinte arquivo de Preferences
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE map SYSTEM 'http://java.sun.com/dtd/preferences.dtd'>
<map MAP_XML_VERSION="1.0">
<entry key=" Mes" value="03_2004" />
<entry key="DiaDoMes" value="01" />
<entry key="EntradaManha" value="08:00" />
<entry key="EntradaTarde" value="12:30" />
<entry key="SaidaManha" value="11:30" />
<entry key="SaidaTarde" value="18:00" />
</map>
para fazer com que a chave <entry key=“DiaDoMes”/> tenha varios values
<entry key=“DiaDoMes” value=“01” value=“08:00” value=“12:30” value=“11:30” value=“18:00”/>
