如何使用动态对象类型创建List

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

public class DynamicList {
    public static void main(String[] args) {
        List<Object> dynamicList = new ArrayList<>();

        dynamicList.add("Hello");
        dynamicList.add(42);
        dynamicList.add(3.14);
        dynamicList.add(new Object());

        for (Object item : dynamicList) {
            System.out.println(item);
        }
    }
}
