Thread: Problem of executing java.exe. How to code from absolute scratch?

I've been reading herbert schildts "java for beginners" and it says in order to compile raw code, i should open javac.exe, and type in x command.

however when i load javac, it appears, loads up the help console, but disappears before i can do anything. i've tried running it as an administrator, i've tried turning my antivirus software off, but nothing makes a difference.

Up to now i've been using the netbeans IDE to do all of my coding, but i wanted to learn how to code from absolute scratch.

Any help would be much appreciated.

if you are using windowsxp~ you can do -> run -> cmd -> javac - parameters.

Unfortunately i'm using vista.

I've got the same tutorials pretty much, problem is, executing javac.exe.

C:\Program Files\Java\jdk1.6.0_03\bin\javac.exe

I open it, and the cmd prompt opens, displays (what i presume is the help console) and disappears before i can type anything.

Any ideas? wouldn't be anything to do with not having the most up to date java would it?

I apologise for being a dunce, as i've only used IDE's i never knew that.

Thanks alot for the help

using the 'cd' command to change directories then type javac.exe

It should load up OK then...

If you have setup the classpath correctly you can type javac instead of going to the java directory.

how do i set it up so that i dont have to cd C:\(path) every time i open cmd to compile?

It should have been done automatically when you install java but if not you can set it in your enviroment variables setting like this:

Hmmm, not sure if Vista is different, i have opened the env vars, and there was no JAVA_HOME, so i've added a new one, called JAVA_HOME, and given it the classpath of C:\Program Files\Java\jdk1.6.0_07

but when i open cmd still gotta use cd to use javac, not sure whether that was the purpose of changing the env vars though lol :-(

Hi,
just had a go at this and had no joy. Can you explain why you've used the path D:\javaSoft\jdk...

Thanks
