Java List集合存储学生对象并遍历

Java List集合存储学生对象并遍历

思路
1、定义学生对象
2、创建List集合对象
3、创建学生类
4、把学生添加到集合
5、遍历集合

代码示例

导包

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

public static void main(String[] args) {
        //创建List集合对象
        List list = new ArrayList();

        //创建学生类
        Student s1 = new Student("张三", 18);
        Student s2 = new Student("李四", 19);
        Student s3 = new Student("王五", 20);

        //把学生添加到集合
        list.add(s1);
        list.add(s2);
        list.add(s3);

        //遍历
        for (int i = 0; i < list.size(); i++){
            Student s = list.get(i);
            System.out.println(s.getName()+","+s.getAge());
        }
    }

Student类

public class Student {
    private String name;
    private int age;

    public Student() {
    }

    public Student(String name, int age) {
        this.name = name;
        this.age = age;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
}
