When compiling a java program via the command prompt and you get an error

[None]

message like...? error: cannot read: Hello.java
1 error

what does it mean?

[anita k]

save hello.java file into the path where jdk1.3 or jdk1.5 lies.
that means in notepad file--save in c:\program files\jdk1.3 by choosing in save in top bar.
-------------------------------------------------------------------
secondly set path in command prompt
then open this c:\program files\jdk1.3 on my computer and copy this address by right clicking on address bar of my computer
then open command prompt and write cd "c:\program files\jdk1.3" . this between quotes can be pasted by right clicking and pasting .press enter key
---------------------------------------------------
> javac hello.java
>java hello

This means that the file Hello.java is not in the directory. You have to create the file before you can compile it. You can use the ls command to check which files are in the directory.
