这是咋回事 运行不了

}
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

--------------------编程问答-------------------- 我的怎么没运行结果，给了几行英文。。。。 --------------------编程问答-------------------- 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;
--------------------编程问答-------------------- 贴出来看看 你用撒运行的 --------------------编程问答-------------------- 有结果了 是环境变量设置问题 。。。。。。 --------------------编程问答--------------------
补充：Java , Java SE
