Thread: Help with Textpad

Hello everyone, I'm new here and also a total java noob and I have no idea where I should of posted this, if this is posted in the wrong category then I apologize. But please don't just lock this, at least give me some direction if you can because I need to finish this program ASAP.

I need to write a program for my college Programming assessment, however I usually use one of the college computers. But now I'm at home and I don't have access to them so I need to finish writing the program on my laptop. I have Notepad++, TExtpad7 and Netbeans on my laptop and I've downloaded JDK. But I can't get any of the IDEs to compile or run my programs. I think I need to add JDK to them, but I can't find out how. If you can help me with any of them, my preference is Textpad as I'm most experienced with that. If anyone can help me please do because I need to finish this program ASAP. All help is greatly appreciated.

What OS are you using?

If you open a console (a system prompt) and type

javac -version

what happens?

Sorry should of stated this, I'm using Win8 64-bit.

When I typed that into the cmd it said "'javac' is not recognized as an internal or external command, operable program or batch file".
But I definitely have JDK downloaded.

--- Update ---

I decided to reinstall Textpad and now it seems I can actually compile stuff but whenever I ever try compile my program "Library.java", it says "Error: Could not find or load main class F:\Programming\Java\Project\Library.java

Tool completed with exit code 1"

The files are stored on a Removable Disk, which has worked perfectly in the past.

"Is the bin folder with javac.exe on the Path variable? "

Sorry I'm a big noob, I don't understand what you mean. I'm used to Textpad being already set and I just press CTRL+1 to compile and CTRL+2 for running. I don't really have any idea on how to set it up. If you can give me simplified step-by-step instructions, I'd really appreciate it.

No not with TextPad specifically, I'm just asking how you do what you saying in post #4.

I honestly don't trust myself in making a batch file as I read that if you do it wrong it can mess up your system. I don't know what part of your example I should modify to fit with my situation. Is there anyway I can write and run java programs on my laptop without having to do this?

"D:\JavaDevelopment\Testing\ForumQuestions9>D:\Jav a\jdk1.7.0.7\bin\javac.exe"

Can you tell me what each file location represents so I can know what part of what to change to my files? Why is it a D drive? A local drive is C isn't it?

My java program file is on a removable disk, so it should look something like this right?
(F: )Removable Disk/Programming/Java/Project/Library.java

and jdk should be in my local disk so it should look like this, right?

(C: )Local Disk/Program Files/Java/java.exe

With this information would you be able to modify what I should actually type in?

I don't know what you mean, I haven't executed any batch file yet because I'm still not sure what to do.

If the batch file is called TestCode16.bat then why does it say .java instead? Also that looks like the folder where the jdk is located, not where my program is.

I haven't tried it since the first time but since I haven't changed anything since then but I imagine I will still get the "'javac' is not recognized as an internal or external command, operable program or batch file". message.

So can I just copy exactly what your batch file says and it will work?

Ok so is this right before I actually do it?

C:\Program Files\Java\jdk1.7.0_45\bin/javac.exe -cp . -Xlint Library.java
MORE

and I save that, call it Library.bat and save it in the same folder as Library.java?

What do I do about this bit?

TestCode16.java:207: error: cannot find symbol
x = 0;
^
symbol: variable x
location: class TestCode16
1 error

D:\JavaDevelopment\Testing\ForumQuestions9>MORE

Ok I ran it and this is what I got:


F:\Programming\Java\Project>C:\Program Files\Java\jdk1.7.0_45\bin/javac.exe -cp
. -Xlint Library.java
'C:\Program' is not recognized as an internal or external command,
operable program or batch file.

F:\Programming\Java\Project>MORE



Any Ideas?

Ok that worked. Here are the results:

F:\Programing\Java\Project>"C:\Program Files\Java\jdk1.7.0_45\bin/javac.exe" -c
p . -Xlint Library.java

F:\Programming\Java\Project>MORE

_



That last underscore is a text prompt


But what am I able to do with it? How do use this to run my java program?

Also using preference->tools and then browsing for the javac file in Textpad I somehow enabled Textpad to read java so now I can compile my programs in Textpad, I don't know if the batch file enabled me to do that or what but at least I can now compile, but I have no idea how to run the program after compiling it. Can I use the batch file to do that? Or is there a command in cmd?

Ok I FINALLY got it working, that you very much for being so patient with me.

Is there any way I can give you a Thumbs Up or a Thanks? Because you definitely deserve it!
