如何使用构造函数从泛型列表中删除基于类的项？

import java.util.ArrayList;
import java.util.List;

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

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

    public void removeItemsOfType(Class<?> type) {
        for (int i = items.size() - 1; i >= 0; i--) {
            T item = items.get(i);
            if (type.isInstance(item)) {
                items.remove(i);
            }
        }
    }

    // 其他操作和方法...

    public static void main(String[] args) {
        GenericList<Object> list = new GenericList<>();
        list.items.add("String");
        list.items.add(123);
        list.items.add("Another String");
        list.items.add(456);

        System.out.println("Before removal: " + list.items);

        list.removeItemsOfType(String.class);

        System.out.println("After removal: " + list.items);
    }
}

Before removal: [String, 123, Another String, 456]
After removal: [123, 456]
