JAVA compiling error! I can't find any solution for that. Help me please.Thank you

waokool(waokool)

Hi,Friends.I am facing a problems about compiling java files.
I just start to learn Java.I installed J2SDK1.4.0_01,and then accroding to
th the tutorial of SUN web site, I tried HelloWorldApp.java. But when I compiled it,
a message says" cannot read: HelloWorldApp.java.
Seveal points need mentioned:
1. no mistake with the java file name. I know it's case sensitive.
2. In DOS prompt, I was in the directory of the java file.
3. I didn't edit path in Autoexec.bat, Because I am not sure how to do it.
Instead, I input full path to implement compiling. C:\j2sdk1.4.0_01\bin\javac filename.
When I only execute C:\j2sdk1.4.0_01\bin\javac, some help infomation shows up.
4.the java file exsits with java appendix.I saw it in dos prompt.
5. the java file is copied from Sun's tutorials, should be Ok.
I spent serveral hours on this stupid problem, but cannot fix it, So please help me.
Don't be too abstract when tell me how to do it.I am just begainning. Thanks a lot.

Give the whole DOS command line of how you tried to compile the thing. -jeffrey815(Smartiecat); 2002-6-24 (#598027@0)

C:\j2sdk1.4.0_01\bin\javac HelloWorldApp.java //* My JSDK is in C:\ -waokool(waokool); 2002-6-24 {407} (#598184@0)
1. I use Notepad to copy the HelloWorldApp code from Sun.
2. I save it with "HelloWorldApp.java" (quote including) in c:\java
3.launch Dos PROMPT.
4. switch to c:\java
5. C:\java\dir //* HelloWorldApp.java is there.
6.switch to c:\
7.C:\j2sdk1.4.0_01\bin\javac HelloWorldApp.java
8.response: "error,cannot read: HelloWorldApp.java "
Thank you so much, I am waiting for your advice.

Repeat everything you have done except Step 6. -jeffrey815(Smartiecat); 2002-6-24 (#598213@0)

Hi,man. you look like have nothing to do except saying some FENG LIANG HUA. I think people here are usually warmheated.Of course, I NEED read book myself, but I also can get some good clues here. -waokool(waokool); 2002-6-25 (#598368@0)

喂，我不是说风凉话，只是觉得你并没有仔细按照别人的指点去做。ＩＴ需要一些灵性的。路太长了。 -member1(工人,大学没毕业,照样); 2002-6-25 (#600247@0)

可以考虑下个简单点的，我推荐kawa，不过已经停止开发了，可能不好找。听说Jpad Pro也不错，url是下载Jpad Pro的链接。 -guestagain(guest again); 2002-6-25 (#598382@0)

请确认你的文件名是HelloWorldApp.java而不是HelloWorldApp.java.txt!!!!!! -mickeymouse(Part Time DBA); 2002-6-25 (#598383@0)

Is that copy:path=c:\j2sdk1.4.0_01\bin, classpath=c:\j2sdk1.4.0_01\jre\lib\rt.jar to Sysedit in Autoexec.bat? I tried but doesn't work.BTW, need reboot or not after modified sysedit? Thanks -waokool(waokool); 2002-6-25 (#598286@0)

什么操作系统啊! 32,95,98,NT,2000,xp,linux,unix啊 -member1(工人,大学没毕业,照样); 2002-6-25 (#598323@0)
no, not in autoexec.bat. it depends on different os. in winxp, control panel-system-advanced-environment variables. make sure u create classpath -breathe(呼吸); 2002-6-25 (#598409@0)
