如何在Java中迭代多个对象列表并获取对象摘要？

import java.util.ArrayList;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;

public class ObjectSummaryIterator {
    public static void main(String[] args) {
        // 创建包含多个对象列表的集合
        List<List<Object>> objectLists = new ArrayList<>();

        // 假设有两个对象列表
        List<Object> list1 = new ArrayList<>();
        list1.add(new Object("Object 1", 10));
        list1.add(new Object("Object 2", 20));
        objectLists.add(list1);

        List<Object> list2 = new ArrayList<>();
        list2.add(new Object("Object 3", 30));
        list2.add(new Object("Object 4", 40));
        objectLists.add(list2);

        // 迭代多个对象列表并获取对象摘要
        List<String> summaries = new ArrayList<>();
        Iterator<List<Object>> iterator = objectLists.iterator();
        while (iterator.hasNext()) {
            List<Object> objectList = iterator.next();
            for (Object obj : objectList) {
                // 获取对象摘要信息
                String summary = obj.getSummary();
                summaries.add(summary);
            }
        }

        // 打印对象摘要信息
        for (String summary : summaries) {
            System.out.println(summary);
        }
    }
}

class Object {
    private String name;
    private int value;

    public Object(String name, int value) {
        this.name = name;
        this.value = value;
    }

    public String getSummary() {
        return "Name: " + name + ", Value: " + value;
    }
}
