Java 一个数组集合List 赋值给另一个数组集合List ，两个数组集合属性部分一致。

下面是一个Demo, 具体要根据自己的业务调整。

import java.util.ArrayList;
import java.util.List;class People {private String name;private int age;private String address;public People(String name, int age, String address) {this.name = name;this.age = age;this.address = address;}// 省略getter和setter方法
}class NewPeople {private String name;private int age;public NewPeople(String name, int age) {this.name = name;this.age = age;}// 省略getter和setter方法
}public class Main {public static void main(String[] args) {List<People> peopleList = new ArrayList<>();peopleList.add(new People("张三", 30, "北京"));peopleList.add(new People("李四", 20, "上海"));peopleList.add(new People("王五", 50, "广州"));List<NewPeople> newPeopleList = new ArrayList<>();for (People people : peopleList) {NewPeople newPeople = new NewPeople(people.getName(), people.getAge());newPeopleList.add(newPeople);}// 输出newPeopleListfor (NewPeople newPeople : newPeopleList) {System.out.println("姓名：" + newPeople.getName() + "，年龄：" + newPeople.getAge());}}
}
