java太难了吧！有点想换专业了(>﹏<)

/**
 * 新闻类

public class News {

    private Integer id; // 编号
    private String newsName; //新闻名称
    private String host; //主持人

    public News() {
    }

    public News(Integer id, String newsName, String host) {
        this.id = id;

    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;

    @Override
    public String toString() {
        return "News{" +
                "id=" + id +
                ", newsName='" + newsName + '\'' +
                ", host='" + host + '\'' +
                '}';
    }
}


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

public class TestNews {

    public static void main(String[] args) {
        News news1 = new News();
        news1.setId(1);
        news1.setNewsName("央视新闻");
        news1.setHost("康辉");

        News news2 = new News();
        news2.setId(2);
        news2.setNewsName("今日说法");
        news2.setHost("撒贝宁");
        List<News> newsList = new ArrayList<>();
        newsList.add(news1);
        newsList.add(news2);
        for (News news : newsList) {
            System.out.println(news);
        }
    }
}

LinkedList：底层双向链表实现，查询慢，增删快，提供大量的首尾操作
ArrayList：底层数组实现，查询快，增删慢，具备索引

LInkedList的I打错了， 应该是小写LinkedList

刚开始学都很难，多写、多练、多看

如果Java觉得难了，那c语言，c++ 压根听不懂了
