This may seem very small thing but it annoys me much since I'm used to code in Eclipse. When I double click a java source file in Eclipse it shows classes inside the file (expanding contents of java file) as marked by red circle in the image below. I wanna disable this behavior, I have used Eclipse for a long time and it has never been like this.
You can go to Prefences --> Content Assist and Enable/Disable the contents of Java file

This is a bug in Eclipse, and several people have reported it, e.g., here.
One workaround is to change the "open mode" in the General preferences to single click", which does not have this annoying behaviour.

For some reason, Netbeans IDE 8.2 won't apply any different themes than the original one. Has anyone else had an issue with this? I have applied the new theme and restarted the application many times without success. Thank you.
It's very hard to identify what is wrong since everything in your screenshot looks perfect, and Sublime-Theme works for me using NetBeans 8.2 on Windows 10. See the file with the tab NewServlet.java in the screen shot below.
Note that using Sublime-Theme does not impact everything. For example, the Projects and Navigator panels don't change. Since your screen shot only showed the Options window, and the Start Page doesn't change in the editor either, are you absolutely certain that none of your files in the editor are using Sublime-Theme?
Also, you say that "Netbeans IDE 8.2 won't apply any different themes than the original one", but NetBeans comes bundled with several themes, such as NetBeans and NetBeans 5.5 as shown in the screen shot below. How many options are shown in the profile drop list for you? If you select a different theme from the Profile list and click Apply the rendering of your files in the editor should change immediately. Is that happening?
If so, the problem is probably confined to the installation of Sublime-Theme. Try deleting Sublime-Theme (the button is in the top right corner of your screen shot), and then import the zip file again to see if that fixes the problem. Also, verify that the Sublime-Theme zip file you downloaded can be manually unzipped since it might be a corrupt file.
Another thing to try is using some alternative plugins. Select Tools -> Plugins -> Available Plugins and then install Dark Look and Feel Themes and Darcula LAF for NetBeans. If those don't work either then there is something fundamentally wrong with the installation of NetBeans.
Finally, this article titled The complete guide to tuning the appearance of NetBeans may be helpful.
Few days ago, I download a new version of Eclipse(4.4.2), and found a new feature on that, is fuzzy auto complete (as the bottom picture in screenshot below).
When I switch to another workspace, this feature has gone, it only allow prefix to auto complete (as the top picture in screenshot).
Did any one know where is this feature's setting in eclipse?
After i half delete/half reserve file in .metadata directory, I found this feature setting in Eclipse finally. Open Preferences dialog, navigate to Code Recommenders->Completions, check the option [Enable intelligent code completion] and [Subwords-Completion Processor].
In an Eclipse based application (RCP), when double clicking on a file that appears in the project explorer, for the first file this will work – the associated editor will open. However, when double clicking again on a file, it will not open. If you click somewhere out of the Project Explorer and then return to the Project Explorer, then the second double click will work.
Note that right-clicking on the resource and selecting “Open” always works. In addition, in Package Explorer it always works.
I believe this is related to eclipse bugs 285239 and 256761.
Does anyone know of a way that I can overcome this problem, as the RCP developer. The file editor is a custom editor in one of my plugins.
The problem does not seem to happen to me with java files in standard eclipse for java development.
Thanks,
Eyal.
I solved the problem by implementing a setFocus method on the editor class. In the setFocus, I set the focus to some component. (To be precise in my case the editor was a subclass of SharedHeaderFormEditor so I set the focus to the active page).
The truth is that the specification of the setFocus method in IWorkbenchPart requires you to "assign the focus to one of the controls contained in the part's parent composite". It seems that the default implementation of setFocus in some cases did not do that (I don't know why, maybe I was missing something or for other reason).
Note that also setting focus explicitly to a control from within editor initializing partialy solves the problem.
I've got a small homework project, and for whatever reason Eclipse has decided to stop highlighting syntax or allowing intellisense or goto definitions or anything in this Main.java file. I've tried rebooting it, and the computer, but had no luck.
The thing that really has me confused is that it's still compiling and running the code correctly (eg, changes I make in Main.java are compiled and run - it's not running old Main.class files), so it's still in the build path ... right?
Any ideas?
Right click on the file in the Package Explorer and choose the Open With menu. You will probably find that Text Editor is selected, choose Java Editor to open the file with the correct editor.
The Open With menu selection is remembered so you should get the Java Editor in future, but equally if you choose the plain text editor that is also remembered.
I suggest finding a way to reset any setting you might have set by accident. Not saying that you did it. But just to make sure, just try it out. If you customized the preferences already, you could make some kind of note of the settings, then change it. If that doesn't work, let me know. Good Luck!
Copy the text somewhere, delete the file, and then add a new class (of the same name) and paste the text back.
I've seem to have lost the ability in my Eclipse to auto-correct errors in my source code lines.
For example, a line like this:
Date date = new Date();
has red jagged lines beneath the Date() part. Previously I could mouse hover over it see a popup menu of options to fix it. Now I all I ever get is a popup with the text "Cannot resolve to a type".
The only change I can think of that I've made and I don't know if it has anything to do with this problem, is that I started editing my .java files with an outside editor. Then focusing back into Eclipse I get a popup saying the source has changed and do I want to update so I say OK.
Sometimes I will edit inside Eclipse and sometimes i will edit the source outside of Eclipse. I'm not sure if this is a bad practice or not?
Its your wish to edit Java files outside or inside eclipse. But Java editor has many features which are very helpful to developers. I suggest to edit Java files inside eclipse only.If you find other editors are good or you used to it then no problem you can edit Java files out side eclipse also. The problem you mentioned in not related to it. But make sure that changes are applied before building project in eclipse.
Solution
This occurs whenever there are multiple classes are available with the same name in you build path then eclipse don't know which one to import by default. So keep the caret on the error line and press Ctrl+1. Then a eclipse gives options to user to import one among these. See the picture below. Choose the right one then error will disappear.
