是你环境变量里的CLASSPATH路径问题。假设：你把这个java文件放在C盘的根目录下。编译后的class文件也在C盘的根目录下。把你的CLASSPATH后面追加上C:\ 然后，到 C:\>javac Train.java C:\>javac Train 再执行就不会出错了。
啥问题?
没有啊,在我的机器上编译通过,也可以正常运行.
你想说什么？？？
D:\>javac Train.java
D:\>java Train
Input weight:
123
Input distance:
456
The money is 44870.4
D:\>
运行了一下你写的，没有错误。
好像程序没有什么错误。是不是编译操作问题。
你要看一下编译器指示的什么错误，然后根据指示找出错误。
