I was watching a tutorial and the teacher's intelli j has a database icon on right sidebar and mine don't. How can I do the same? Or there's another way to access it?
You may put it via selecting View -> Tool Windows -> Database. Assigning a shortcut it is also useful. You may assign it in the Keymap.

Is it possible to use J and K when choosing a suggested auto-completion item? See the image below: I'd like to, maybe hold ALT or SHIFT (or in some other way differentiate between moving and typing), and use J and K to select the proper suggestion.
Is anything similar also available for moving around the menus (in Project view etc.)?
I was able to make this work by creating a shortcut ALT+J mapped to the Down key and ALT+K to the Up key.
You can move up and down in the popup without needing to move your hand away from HJKL to the arrow keys.
This also works in the Find in path window, though it does not work in the navigation menu.
Update: For Alt + K to work in the Find window since the version 2020+, one has to disable mnemonics in Settings, under Appearance & Behaviour -> Appearance -> Disable mnemonics in controls.
#Rok Povsic's solution is great and I used it a bit, but in some pop up menus like Intention actions, refactoring menu or usages the trick won't work.
So I used this Power Toys program from Microsoft to remap the Alt+J, Alt+K, Alt+H, Alt+L to arrow keys at windows level and now this works great everywhere around the IDE.
You can even specify only the app in which you want to override this shortcuts. For example for rider it will be "rider64.exe". You can find the name of the app you want to use in task manager under "Details".
I am a new to IntelliJ IDEA and somehow my project structure doesn't appear where It should be. Someone know how to fix this please? I want it to appear left corner where red circle:
You have hidden the tool window buttons. To show them again press Alt+Alt (and keep holding) or click on the bottom left corner icon. Or use View | Tool Buttons to show them permanently. Then you can click on the Project or Structure tool window buttons depending on what you need.
Another way is to use the menu: View | Tool Windows | Project (or Structure).
Or just use the keyboard shortcuts:
Alt+1 — Project
Alt+7 — Structure
You can find more details in the online documentation:
Manipulating the Tool Windows
In Eclipse I could hit Ctrl+O and get a popup which I could use to get an overview of everything in the current class, pick an entry, and jump to it.
In idea, there is Alt+7, but I have a few issues with it. First, the keyboard doesn't seem to put its focus there. I have to take my hand off the keyboard and use the mouse to place the focus on the Structure dock.
I also don't like how it's taking up real estate. I don't want to change how things are laid out if I want to see the structure. I would like a more non-invasive popup, and handier and snappier.
Is there another feature that gives me quick access in the form of a popup preferably, like Ctrl+O provides in Eclipse?
Another nice feature would be to be able to use the J and K keys to move up and down the selection, instead of having to use the cursor keys. I'm using IdeaVim, so the normal workflow when editing files, is that both hands stay in a touch-type position. It would be nice if I can use the various navigation features also using vim keys...
Perhaps there is a way to enable this, that I haven't discovered yet?
IntelliJ equivalent of Eclipse's CTRL+O is CTRL+F12 (⌘+F12 on Mac), which will give you more or less the same pop-up as in Eclipse. But I'm not sure if it can be navigated using j and k keys.
More details can be found in the IntelliJ help.
I've a question. I cannot find the way, how to add buttons to main toolbar programmatically. My problem is, that I've the task to dynamically (based on XML configuration file) build menus and toolbar. I found how to add a menu item programmatically, but not toolbar button.
Tutorials mostly show how to create buttons and menus using plugin descriptor (plugin.xml), but not how to do it programatically. It seems, that it is out of bounds of Eclipse plugin philosophy.
I've just found this:
There might be layout problems with this approach. I also don't
believe the framework will try and re-create your dynamic item except
at random toolbarmanager updates. With Menus they can be updated on an
SWT.Show event, which is why CompoundContributionItem only applies to
Menus.
What shall I do? Can I say Sorry, there is no way to build toolbar dynamically. I can do it just for menus? Collegue says, that it must be possible, but he does neither know how.
The only way to be able to create main toolbar entries programmatically is in an RCP app, where you supply the ActionBarAdvisor for the workbench window. This isn't dynamic, however, just called on window creation.
Another way to do it would be to use org.eclipse.ui.menus and contribute org.eclipse.ui.menus.ExtensionContributionFactory. It also works only on workbench window creation (not really dynamic), but you could read your own XML and provide IContributionItems for the main menu or toolbar.
How dynamic are you trying to be? Most solutions work well on startup/window creation.

Whenever you try to do something programmatically in Eclipse that is normally done through plugin definitions you are walking on thin ice. I've tried it on a few occasions and it rarely ended up being easy or good.
Instead, think of what it is that you only know at runtime and need to be able to change on the fly. Is it the name or icon of the button? That can be changed at runtime.
Take a look at runtime commands, they can be confusing to define properly, but with them you can for example create buttons that are only visible if a condition is active. That condition could be set at runtime.
In our code base there are a few very long methods (several pages worth of code). When reading the code, it would sometimes be good to be able to see the name of the method the current line belongs to, without paging up to the beginning of the method. Is this possible in Intellij IDEA? I am using Intellij IDEA 7.0.3.
You can use View | Context Info (Alt+Q, Ctrl+Shift+Q on Macs). It will display a pop-up on the top of the editor with the current context information (class/method signature).
IntelliJ 2018
This is shown by default at the bottom.
Unfortunately, the method is shown only by name (not including the parameters). If a method is overloaded you won't know for sure where you are.
If you want to move it from bottom to top, go to File > Settings... > Editor > General > Breadcrumbs > check Top:
In the structure panel select the "Autoscroll from source" option.
This way when you place the cursor inside any method the structure panel will show which method you're in.
Intellij now has support for breadcrumbs. Go to settings > appearance and tick "Show breadcrumbs". In this way you can view class/method name without Alt+Q.
For some reason (Alt-Q) wasn't consistent in Android Studio for me. I find (Ctrl-F12) to be pretty satisfactory for this purpose (Navigate|File Structure) though it can be a little laggy in larger files. And by pressing the hotkey again it will populate the list with all the inherited methods as well.
