This isn't exactly a programming question, but my goal is to add a comment at the top of the class that shows when you last edited the file, updating when it saves. I know Eclipse can access the date and time, since adding a "Date Created:" comment was easy, but that's just editing the new file code templates so I would imagine it's not in the same area. I've been learning Java and Eclipse for about a year now, and this would be super helpful to keep track of files.
Here's a picture in case I wasn't clear
No, not out of the box. Someone could write a plug-in to do it, but as the comments have mentioned, once you're past a trivial example, this is usually the job for a source control system.

I actually don't remember what I did/installed precisely, but it should be something along the line of "installing Java Debugger". This is giving me a lot of(more than one thousand) .project untracked files, even if I delete them, they pop back up again.
Edit: Just found this link: What project files does Visual Studio Code create via its Java extensions? , it seems like the question is the situation I'm in right now, but the answer is still very confusing. So what should I do?
Thank you!
Currently I am working on a program that will assist me for making decisions when trying to bet on sports. My goal is for the program is that each day I would like to retrieve things like weather, past games, player/team stats etc. then aggregate it all so that I can see which teams make the most sense to bet on.
I'm not exactly sure if it's even possible to do on IntelliJ, the text editor I'm using, because I do not think its connected to the internet on its own. I think one approach would be to use a separate program (not IntelliJ) to automatically go to each website and copy the appropriate information into an excel document; then I could copy the file into my project each day before I run it. Something like that is what I have in mind, but I would appreciate some help if anyone knows which strategy I could use to move past this obstacle.
I've recently learned how to and created a GUI to navigate my program a little easier than through the console; therefore, my work ethic is not an barrier in this instance. I've taken one programming class in college and would consider myself an apprentice (one step above a novice).
You can use jsoup for scraping data from a website, Then you can use Apache POI to add it to an excel file.
Heres the website https://jsoup.org/
Heres a good tutorial about apache POI https://www.baeldung.com/java-microsoft-excel
I am very new to IntelliJ Plugin Programming and mainly got to it because my current project requires me to do the same steps again and again and only having small differences.
Becauste this takes a lot of time, I decided to take like some hours once to create a plugin which does the most work for me and then save a lot of time when having these steps again.
My question is basically how I can create new class files programmatically with the IntelliJ Plugin API. I already found out how to get the content of the currently open and in editor selected file and also how to change the content, but now how to create completely new files in a specific package.
To be honest, I think there must be something in the documentation but I already wasted like 1 hour for googling without any success. So I hope some of you guys are already experienced in creating plugins for IntelliJ Platform and maybe you can send me a good handbook or reference. I don't think that I have to write a lot of plugins but sometimes, they can really help.
Thanks in advance.
Please see Meo's tip for com.intellij.ide.actions.CreateClassAction#doCreate.
The code does the following:
return JavaDirectoryService.getInstance().createClass(dir, className, templateName, true);
And from here we can see different signatures in JavaDirectoryService
Perhaps this one might be relevant:
public abstract PsiClass createClass(#NotNull PsiDirectory dir, #NotNull String name) throws IncorrectOperationException;
I have been coding for about a month and I have found ways to adapt around ever problem but one. The problem as you can probably see by the title is how to make a way to make game saves. I am currently creating a very simple game that has about 5 classes of my code and maybe 2 of Java Swing GUI.
I know how I would like to go about the saving process but I have no idea how to do it in my code. How I would like to go about doing this is by making the code print a Number or Integer to a file to represent a Level. For example if you completed level 1 the number in the file would be 1. I have tried some templates for this but none of them work.
I understand how to write to a file but my problem is reading it from a jar or even creating a file then reading it from a place on the computer. I need to know how to find a file URL for different computers because some use Docs and Settings and other Users. Please could someone help.
Since the jar is read only, it can only contain the 'default settings'. See this answer for the general strategy to deal with such a embedded-resource.
Speaking of which (embedded resources) see the info. page for more details on how to access them.
Here is an example of storing and reading a Properties file from the 'current directory'.
As mentioned by #MadProgrammer though, it is safest to put the settings file into a (sub-directory) of user.home, as seen in this answer.
But a properties file is just one option. You might also serialize an object, or write the file in a custom format that your app. knows how to read, for the first two off the top of my head.
Besides 'serialize (in some form) in a File', there is also the Preferences API, or for desktop applications launched using Java Web Start, the PersistenceService. Here is a demo. of the service.
I need to know how to find a file url for different computers because
some use Docs and Settings and other Users
The System property user.home points to the user's home directory
File userHome = new File(System.getProperty("user.home"));
Ok, Please be gentle and kind. I am taking an Android Programming class in college and its our teachers first semester so he is learning as we are... Nothing against him, he's a good teacher, just doesn't know the answer.
I don't know how to put this in Android/java language so here goes...
Is there a way to use something similar to Includes, in web design, in Android. I am looking to add similar java code from one activity to the next, can i make a file that if i change this one file it will change in all the files its included it.
I know it can be done with the XML files but i couldn't find anything to show that it can be done in the actually coding... but then again i don't know the correct terminology. Please any help would be great. And thank you for taking the time to read and answer me. I apologize if this was somewhere else, I just couldn't find it.. Thanks again
Put anything you wish to "include" in Java classes, then import them. http://leepoint.net/notes-java/language/10basics/import.html
Android Programming class! I would've loved that in University...
Regardless, if you're using Eclipse for your IDE, it should pickup any changes from your java imports automatically. If you choose to refactor other java classes within your project, a rename for example (with "Update All References"), will update all references to that class across your project.
You could also use Maven (dependency management) to pull the latest third-party (or other) .jars at build time, if that's applicable to what your needs are.
