java循环list_Java中List集合的三种遍历方式(全网最详)
介绍3种方式遍历list集合
1 创建一个model
public class News{
private int id;
private String title;
private String author;
public News(int id, String title, String author) {
super();
this.id = id;
this.title = title;
this.author = author;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getAuthor() {
return author;
}
public void setAuthor(String author) {
this.author = author;
}
}
方式一 第一种、最基础的遍历方式：for循环，指定下标长度，使用List集合的size()方法，进行for循
