How do i add a java class to an existing project??

[chaoscreater]

Hi guys, i'm new here. First of all, it's my very first time using Netbeans, i'm currently an UNI student and not very familiar with JAVA or any of the other tools yet, so please guide me through.

I was previously using Notepad++ but recently have heard about Netbeans, that it uses a really good GUI interface where i can use it as a WYSIWYG to build my JPanel, so i installed it yesterday and tried to do a few things and encountered some problems.

The first problem is, it seems i can't compile an existing .java file i created. I can open it and view it fine, but i can't compile or run it at all.

So then I referred to the tutorial and apparently I have to create a new project first. So i did, and the project came with a demo class, and i was able to compile and run it fine.

So this brings up my 2nd problem. After creating a project, I thought ok, maybe i just need to add my existing .java files/classes to the project and that'll work, but i've been trying to figure this part out for the past 40 mins or so and read a lot of documentation and guides on Netbeans and couldn't find out how.

Most of the guides i found were to add the .JAR files to the Libraries, which is found by going to the project file and choose Properties. But my files are in .java so not sure what to do here.


So basically, is there a way to simply compile and run the .java file in Netbeans without opening a project?? And lastly, how do i add a .java file to an existing project?


Please help me out, thanks.

No/Yes.

You can't just open a file and compile it from NB.

Copy the files to the project, right click the project, open the properties, go go run, and select your program

Please direct beginner questions to the correct forum. This forum is for web and enterprise development.

Well, you can copy your package in the source folder of your NB project.

I guess you have your classes inside a folder/subfolder/... Copy from the
root folder
in the src/java/ folder of the NB project (you will see it for the other
packges).
The IDE will open this package into your project.
