创建若干个学生放到数组中, 然后按照年龄对数组中的学生进行排序

package cn.Work1202.hooong_10;

public class Students {

    private String name;
    private int 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;
    }

    public Students() {
    }

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

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

public class Demo {
    //创建若干个学生放到数组中, 然后按照年龄对数组中的学生进行排序
    public static void main(String[] args) {
        Students s1 = new Students("小一",15);
        Students s2 = new Students("小一",20);

        s[2]=s3;
        s[3]=s4;

        for (int i = 0; i < s.length-1; i++) {

                    s[i].setAge(s[i+1].getAge());
                    s[i+1].setAge(temp);
                }
            }
        }
        for (int i = 0; i < s.length; i++) {
            System.out.println(s[i]);
        }
    }
