集合练习（键盘录入学生信息，保存到List集合中

输入学生信息，然后保存到集合中

学生类：

package Practice;

import java.util.Objects;

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;
    }

    @Override
    public String toString() {
        return "Student{" +
                "name='" + name + '\'' +
                ", age=" + age +
                '}';
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        Student student = (Student) o;
        return age == student.age && Objects.equals(name, student.name);
    }

    
}

测试类：

package Practice;
import java.util.ArrayList;
import java.util.Scanner;

public class StudentTest {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        ArrayList list = new ArrayList();
        System.out.println("请录入学生信息");
        while (true){
            System.out.println("1：继续录入，0：结束录入");
            int a = scan.nextInt();
            if(a==0){
                break;
            }
            System.out.print("请输入学生姓名：");
            String name = scan.next();
            System.out.print("请输入学生年龄：");
            int aeg = scan.nextInt();
            Student s = new Student(name,aeg);
            list.add(s);
        }
  //遍历集合中的学生信息
        System.out.println("遍历学生信息：");
        for (Object s : list){
            System.out.println(s);
        }
scan.close();
    }
}

结果：

请录入学生信息
1：继续录入，0：结束录入
1
请输入学生姓名：李华
请输入学生年龄：18
1：继续录入，0：结束录入
1
请输入学生姓名：Bob
请输入学生年龄：20
1：继续录入，0：结束录入
0
遍历学生信息：
Student{name='李华', age=18}
Student{name='Bob', age=20}
