2.将课程的编码、课程名称、考试日期、教师姓名 定义为类变量，并添加一个类方法用于设置这些类变量的值，添加一个类方法用于输出这些类变量的值，在主方法中通过类名.类方法名设置课程信息和输出，而学生信息通过构造方法设置。

Exp5_2类：package exp5_2; public class Exp5_2 {

public static void main(String[] args) { ScoreReport stu[]=new ScoreReport[2];

stu[0]=new ScoreReport(\小李\ stu[1]=new ScoreReport(\小陈\ ScoreReport.printCourse(); System.out.println(stu[0]); System.out.println(stu[1]); } }

ScoreReport类：package exp5_2; public class ScoreReport { static String courseID; static String courseName; static String testDate; static String teacherName;

String stuID; String strName; int score;

public static void setCourse(String ID,String Name,String Date,String teacher)
