输入:d:>javac HellorWorld.java
编译成功(没有任何提示)
再输入:d:>java HellorWorld
显示:Esception in thread "main"java.long.NoClassDefFoundError:HelloWorld
是哪里出错了???????

谢谢各位的支持。
我的环境变量如下设置的:(j2sdk装在c盘)
CLASSPATH=C:\j2sdk\lib\dt.jar;C:\j2sdk\lib\tools.jar;C:\j2sdk\bin
JAVA_HOME=C:\j2sdk
PATH=C:\j2sdk\bin

better be
SET CLASSPATH=.
(search to check and understand what dt.jar and tools.jar are for)
SET JAVA_HOME=C:\j2sdk
SET PATH=%JAVA_HOME%\bin;%PATH%

有可能是你的文件名字和你的类名不一样,把文件名和类名一样应该就没有错误了!
