定义一个学生类，通过数组实现多个学生信息（姓名、学号、年龄、性别）的输入和输出。

package wenjian;

public class Student2 {
public static void main(String args[])
{
student stu=new student();;
stu.getage(18);
stu.getclass_number("xingguan");
stu.getname("tom");
stu.getnumber("20090600");
stu.getsex("boy");
System.out.println("name is: "+stu.name+" number is: "+stu.number+" class_number is: "+stu.class_number+" sex is: "+stu.sex+" age is: "+stu.age);
stu.changeage(19);
System.out.println("name is : "+stu.name+" number is: "+stu.number+" class_number is : "+stu.class_number+" sex is :"+stu.sex+" age is: "+stu.age);

}

}
class student
{
static String number;
static String class_number;
static String name;
static String sex;
static int age;
void getnumbe
