学习java编程的好程序

/////创建一个学生类，并且让这个学生类实现comparable接口，这样的话，就可以对类中的数据进行排列整理。
///name指学生的姓名
///age指学生的年龄
///sexy指学生的性别
///code指学生的学号
///school指学生所在学校的名称
///grade指学生的年级
///major指学生的专业
///address指学生家庭住址
///set函数是一个设置器
///get函数是一个访问器
import java.util.*;
///主运行类
///st1至st10是创建出来的学生类的十个对象
///set方法设置了对象的参数值
///arrary是用来排列对象中的数据
