高分悬赏Java程序，急！！！

高分悬赏Java写程序，要求自己亲自运行过没问题的 谢谢 追加分！不要随便复制给我的。~

分为两个类编写。第一个类：
package study;class Student{//由键盘输入3个学生成绩(国文、英文、数学)，并算出其平均private int id ;private String name ;private int gy ;private int wy ;private int sx ;public Student(int id,String name,int gy,int wy,int sx) {this.id=id;this.name = name;this.gy = gy;this.wy = wy;this.sx = sx;}public String toString(){return "学生ID："+this.id+"姓名：" + this.name + "；国语成绩："+ this.gy+"；外语成绩："+ this.wy+"；数学成绩："+ this.sx+"；平均成绩："+ (this.gy+ this.wy+ this.sx )/3;}}第二个类：package study;import java.io.*;import java.util.Scanner;public class Test {public static void main(String[] args)throws Exception {Scanner s = new Scanner(System.in); Student[] stu = new Student[3]; for (int i = 0; i < stu.length; i++) {System.out.print("请输入第"+(i+1)+"个学生的ID：");int id=s.nextInt();System.out.print("请输入第"+(i+1)+"个学生的姓名：");String name=s.next();System.out.print("请输入第"+(i+1)+"个学生的国语成绩：");int gy=s.nextInt();System.out.print("请输入第"+(i+1)+"个学生的外语成绩：");int wy=s.nextInt();System.out.print("请输入第"+(i+1)+"个学生的数学成绩：");int sx=s.nextInt();stu[i]=new Student(id, name, gy, wy, sx);} PrintStream ps = null ;// 声明打印流对象ps = new PrintStream(new FileOutputStream(new File("d:" + File.separator + "stud.txt"))) ;for(int i = 0; i < stu.length; i++){ps.println(stu[i]);}}}亲测可行，生成文件在D盘的stud.txt文件中，最近正在学习，可以互相交流，支付宝就免了
