是否可以在复合组件中调用参数化方法签名？

public class CompositeComponent<T> {
    private List<T> items;

    public CompositeComponent() {
        items = new ArrayList<>();
    }

    public void addItem(T item) {
        items.add(item);
    }

    public void processItems(Consumer<T> consumer) {
        for (T item : items) {
            consumer.accept(item);
        }
    }
}

CompositeComponent<String> stringComponent = new CompositeComponent<>();
stringComponent.addItem("Hello");
stringComponent.addItem("World");
stringComponent.processItems(System.out::println);

CompositeComponent<Integer> integerComponent = new CompositeComponent<>();
integerComponent.addItem(1);
integerComponent.addItem(2);
integerComponent.processItems(System.out::println);
