В чем разница между шаблонами проектирования Adapter и Decorator

interface Target { void request(); }
class Adaptee { void specificRequest() { /*...*/ } }
class Adapter implements Target {
    private Adaptee adaptee;
    public void request() { adaptee.specificRequest(); }
}

interface Component { void operation(); }
class ConcreteComponent implements Component { /*...*/ }
class Decorator implements Component {
    private Component component;
    public void operation() { component.operation(); /* + доп. логика */ }
}
