我可以在Java中为不同的List<>创建泛型构造器吗？

public class GenericConstructor<T> {
    private List<T> list;

    public GenericConstructor() {
        list = new ArrayList<>();
    }

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

    public List<T> getList() {
        return list;
    }

    public static void main(String[] args) {
        GenericConstructor<String> stringList = new GenericConstructor<>();
        stringList.addItem("Item 1");
        stringList.addItem("Item 2");
        System.out.println("String List: " + stringList.getList());

        GenericConstructor<Integer> integerList = new GenericConstructor<>();
        integerList.addItem(1);
        integerList.addItem(2);
        System.out.println("Integer List: " + integerList.getList());
    }
}
