设计一个类Student，并在Main类中生成Student类对象进行测试1.对于Student类，设计私有属性name和age，并为每一个成员变量name和age设计其setXXX（）和getXX

import java.util.Scanner;
class Student{
    private String  name;
    private int age;
    
    public String getName(){
        return name;
    }
    public void setName(String name){
        this.name = name;
    }
    public void setAge(int age){
        if(age<=6){
           this.age = 7;
        }else{
             this.age = age;
        }
    }
    
    public int getAge(){
        return age;
    }
    
    public Student(){
        name = "无名";
        age = 7;
        System.out.println("无参构造方法");
    }
    
    public void display(){
        System.out.println("name:"+name+",age:"+age);
    }
}

public class Main{
    public static void main(String[] args){
        Student student = new Student();
        Scanner scan = new Scanner(System.in);
        student.display();
        student.setName(scan.next());
        student.setAge(scan.nextInt());
        student.display();
    }
}
