Answer 1

你的代码可以运行呀package test;public class Course {
    private String courseID;
    private String courseName;
    private String courseType;
    private int courseHour;
    private float credit;    public Course(String courseID, String courseName, String courseType,
    int courseHour, float credit) {
this.courseID = courseID;
this.courseName = courseName;
this.courseType = courseType;
this.courseHour = courseHour;
this.credit = credit;
    }    String getCourseName() {
return courseName;
    }    void setCourseName(String courseName) {
this.courseName = courseName;
    }    String getCourseID() {
return courseID;
    }    void setCouseID(String courseID) {
this.courseID = courseID;
    }    String getCourseType() {
return courseType;
    }    void setCourseType(String courseType) {
this.courseType = courseType;
    }    int getCourseHour() {
return courseHour;
    }    void setCourseHour(int courseHour) {
this.courseHour = courseHour;
    }    float getCredit() {
return credit;
    }    void setCredit(float credit) {
this.credit = credit;
    }    public void print() {
System.out.println("课堂基础信息如下:");
System.out.println("coursID:" + this.getCourseID());
System.out.println("courseName:" + this.getCourseName());
System.out.println("courseType:" + this.getCourseType());
System.out.println("courseHour:" + this.getCourseHour());
System.out.println("credit:" + this.getCredit());
System.out.println("------------------------");
    }    public static void main(String args[]) {
Course cs = new Course("D13", "java program design", "cs", 64, 3.0f);
System.out.println("-------------");
cs.print();
System.out.println("修改后的信息：");
cs.setCredit(4.0f);
cs.print();
    }
}

Answer 2

运行结果：
-------------
课堂基础信息如下:
coursID:D13
courseName:java program design
courseType:cs
courseHour:64
credit:3.0
------------------------
修改后的信息：
课堂基础信息如下:
coursID:D13
courseName:java program design
courseType:cs
courseHour:64
credit:4.0
------------------------

Answer 3

可以运行的，你在什么环境运行的，如果是在命令行，请检查JAVA_HOME设置：
jdk目录的具体路径，比如   ;D:\Program Files\Java\jdk1.6.0_10;ClassPath设置：
;.;%JAVA_HOME%\bin;%JAVA_HOME%\lib;%JAVA_HOME%\lib\tools.jar;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\jre\lib\rt.jar;Path设置：
;%JAVA_HOME%\jre6\bin;.;%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;
