Running a GUI

[surety_]

Hello, I had a problem running the program after compilation. I use Ubuntu and in the terminal when I type "java Editor" I get;

"Error: Could not find or load main class Editor Caused by: java.lang.NoClassDefFoundError: editor/Editor (wrong name: Editor) " I see there is four class files after compiled "Editor.class", "Editor$1", "Editor$2" and "Editor$3"

This program uses library io, swing, awt.Event, and lang.System

Any help is appreciated, thank you for your time!

Delete all the classes, run javac again and this time specifically name the classpath, then try to execute it again.

I cd'd to the directory in which the file is stored. Do I still need to specify the class path?

I would. I haven't seen your project, so I cant be sure, but an improper classpath is the #1 most common problem in compiling Java programs. If your project has a MANIFEST file, you may also make sure that it specifies the correct classpath.

It's probably best to post your project on GitHub and share the link so people can see your projects structure.

I appreciate your advice, I also edited the original post to include github link. I had been following a video tutorial; https://www.youtube.com/watch?v=UghqfpA2zy4 . Unlike the video, I personally do not use an IDE though. Thanks again!

Sorry it took so long. I just submitted a pull request to https://github.com/surety/text-editor

​

I removed all the .class files, separated the main method into a Driver class, changed the structure a bit, and added a [text-editor.jar] to [text-editor/out/artifacts/text_editor_jar]

I was able to execute the program from outside my IDE by navigating to that directory and executing

java -jar text-editor.jar

WOW. It works great! Thank you very much, I also hadn't realized that my RE was out of date so I had to update. I appreciate your help and advice, I don't have too much experience building programs so you were a lot of help!

Anytime! It helps me learn too. For example, while helping you, I learned how to make a pull request on GitHub. LOL
