'javac' is not recognized as an internal or external command, operable program..

It is set in my path directory, here it is copy and pasted,

C:\Users\Trevor>path
PATH=C:\Program Files (x86)\AMD APP\bin\x86_64;C:\Program Files (x86)\AMD APP\bi
n\x86;C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Program Fil

m Files (x86)\Java\jdk1.7.0_02\bin;

Please Help with why I am receiving this error

In addition, I can navigate using cd to the bin folder, and type in javac and it will print out..

javac Project0.java works when the java file is in the bin folder, but not outside...

Try to get rid of the space before the "C:" in your path variable and get rid of the trailing semi colon as well. See if it helps ...

kind regards,

Jos

It is working now, I believe the space is what was doing it, I had it before without the semicolon, and it wasn't working, must've been the space, thanks so much!

You're welcome of course; I'm glad it works now.

kind regards,

Jos

I tried doing that too.. but this same error shows to me...i tried installing the setup jdk 7 on my windows xp but still after installing and running the setup when i go to the comand prompt and try to compile java, it shows 'javac' is not recognized as an internal or external comand..
Please help me out!

It's always the same: if javac.exe is stored in directory 'X', add 'X' to your path environment variable. If it still doesn't work, javac.exe isn't stored in directory 'X' or you have incorrectly set the path variable.

kind regards,

Jos

Thank you, It really helped me too

I have set the path correctly and still it is not working , is there any other way to solve this problem?
"javac' is not recognized as an internal or external command, operable program.."

No matter what you say, you haven't set the path variable correctly; it should contain the directory where that javac.exe file is stored. Case matters, no additional spaces, no typos etc.

kind regards,
