interface IComponentFactory {
public Component createComponent(String id);
}
List<IComponentFactory> components = new ArrayList(....)
components.add(new IComponentFactory() {
public Component createComponent(String id) {
return new MyComponent(i);
}
});
so instead of storing the component instances directly you just store
factories instances and you delay the actual component creation until
you know the id.
