Question

I dad left Java since so long as a result now it happens that sometimes I forget the simple things and used to behave like a Stupid.

To run a Simple Java program say “Hello World” written in Notepad what do I have to Do?

I know the commands javac “Filename.java” and java “Filename” respectively to run it from the Command prompt.

But When I try to do that I got this message:

“javac is not recognized as an internal or external command, operable program or batch file.”

and I could not Complie the file.

I hava little idea that we need to do some stuffs like setting the classpath or perhaps the path evnironment variables but it was exactly that I don’t remember.

Can anybody please help me?

Thanks,
david

1) create JAVA_HOME environmental variable set value to java home directory

e.g. c:\program files\java\jdk1.5;

1) set PATH in environmental variable to your java bin directory

e.g. %JAVA_HOME%\bin

and to check classpath is set correctly run javac command on cmd
