Folding (collapse/expand) codes in Intellij (How does it look like Eclipse?)

I got to InteliJ from Eclipse. So, I am programming in Java (for Android) in InteliJ now.
I have problems with FOLDING (collapse/expand) style in IntelliJ.
This is a sample of code folding in Eclipse (and I love it) :
and This is code folding in Intellij (or Android Studio) and I hate it :
Is it possible to convert code folding style in InteliJ to Eclipse? (Eclipse folding is my target)
I want to hide #Override or any annotations from all methods in IntelliJ
I want to hide folded symbol {...} or move it in method name line in IntelliJ
Like this :
(in following picture, I removed #Override manually. so,I've moved to manually bracket { to the method name line.
)
Update 1 :
I tried to solve my problem in (Intellij) File -> Settings... -> Editor -> Code Folding , but I could not solve.

For Android Studio:
File --> Settings --> Editor --> General --> Code Folding
From that section you can select the way you want to fold your methods and inner classes etc.
Hope this helps.

You can change it by changing code formatter style.
For Mac :
Eclipse -> Preference -> Java -> Code Style -> Formatter -> Edit
For Window :
Window -> Preference -> Java -> Code Style -> Formatter -> Edit
Please check below links for more details.
http://www.wikihow.com/Change-the-Default-Format-Settings-in-Eclipse

Open Eclipse.
Click on the top tool bar and then click on Preferences.
On the left side of the box, expand Java option, expand Code Style, and click Formatter.
The active profile must be set to Eclipse[built-in], you cannot edit this setting, so make a new one by clicking the New... button.
Enter your new profile name and click OK.
You will now be presented with the "Profile 'name you set'"box.
There are 8 tabs: Indentation, Braces, White Space, Blank Line, New lines, Control statements, Line wrapping, Comments.
Click on each tab and make the changes. Dont forget to click Apply.
Now to format the current document, click on Source from the menu bar, click Format or press Ctrl+Shift+F.
Job well done. =)

Why sysout won't work?

I checked the preferences settings in my Eclipse, it's all set to default with sysout option on, but when I typed sysout in eclipse, it won't automatically go into System.out.println().
I've checked several other related topics which mention ctrl + space.
It is a shortcut for input method on my computer. I don't know if this is related to my unable to use the sysout. If not, please let me know how I can get my sysout working.
If yes, please kindly let me know how I can reset 'ctrl + space' or set other shortcut for content assistant.

Eclipse > Preferences > Java > Editor > Content Assistant > Advanced
Make sure Template Proposals is checked in one of the shown lists.

In recent version of Mac (10.14.1) , Mac OS Settings --> Keyboard --> Shortcuts(tab) --> Input sources.
uncheck the setting ctrl +Space.
Now go to Eclipse IDE and it should work.

You have to press Ctrl + Space for the sysout (or equivalently: syso) shortcut to work in Eclipse, as sysout is not part of Java in anyway, on the contrary: it's an abbreviation introduced in Eclipse that only works after you press Ctrl + Space and expands to System.out.println().
By the way, syserr (or equivalently: syse) will expand to System.err.println() after pressing Ctrl + Space.

public static void main(String[] args)
This public static void ... blah blah has to be put for the sysout
to work

After trying all the answers above with no success I found another reason why Ctrl+Space could be prevented from working.
In my instance Ctrl+Space worked for some projects in the workspace but not others. I discovered that the project that it did not work for did not have the jdk in the build path, instead it had the jre for the application server (weblogic 12). The application ran fine on the server but Ctrl+Space to open the template proposals didn't work and other things like syntax highlighting were not quite right.
I hope this helps anyone who comes to this questions 3 years after it was asked (Like I did).

Eclipse Shortcuts:
Syso + Control + Space: Puts System.out.println()
Alt + Shift + R: Rename
Control + F11: Run
ALT + Up/Down: move the current line (or lines selected) in the editor up or down
Control + Shift + O: Import
Control + I: Indent
Control + D: Delete Line
Control + H: Search Your Entire Project

I had the same problem achieving simple ctrl+space templates with eclipse using jre. Showed empty templates for everything.
Try installing the jdk in separate directory then add into Preferences / Installed jre: add in the new directory. Then use that in your build path. It should solve the problem.

Is there anyway to modify the keyboard shortcuts in eclipse? here you can find out how to make a custom shortcut Window -> Preferences -> General -> Keys
edit: here is a video tutorial http://eclipseone.wordpress.com/2010/02/03/how-to-manage-keyboard-shortcuts-in-eclipse/

For me sysout in eclipse created in two lines. println() in new line..Then I found myself how to avoid this and get System.out.println in one line ..go to Windows > Preferences > Java->Templates (or type templates on search field in top left corner box).Then In template configuring section uncheck "use code formatter"..thats it.. :)
System.out
.println();

Seems like you in windows and your keyboard shortcut for eclipse is got replaced with the system keyboard shortcut for language. well, either you replace it the keyboard combination to shows the template proposals by :
1. open the preferences dialog
2. go to general -> keys
3. in the search dialog, find the command `Content Assist`
4. change the binding and then click OK button
or, you can change the combination key to change the language in the Text Services and Input Language and then go to the Advanced Key Settings tab and then change the key sequence.

Select in the menu bar "Window > Preferences > Java > Editor > Templates"
deselect at the lower end of window: "Use code formatter"

In my case it didn't work because ctrl+space was being used by another program Ubuntu(I-Bus) in my case ref. here Try changing ctrl-space by another key combination in general->keys to find out if this is causing the problem.

I started having the same problem with sysout shortcut when I installed the Scala plug-in in Enclipse. None of the answers worked, but the solution turned out to be very simple. I unchecked all Scala templates in Preferences -> Scala -> Templates So if you use any plug-ins, make sure their templates do not get in the way of your Java templates.

I was facing the same issue. If you use OS X Eclipse Ctrl+Space shortcut can be interfering with OS X system's "Selecting previous input source" shortcut using Ctrl+Space shortcut as default. OS X system shortcut has higher priority, that is the reason why Eclipse does not work.
Just go to System Preferencies/Keyboard/Shortcuts/Input Source and uncheck the "Selecting previous input source" or change the shortcut on something else. Eclipse should work after that even without restart.

I had the same problem. I had ctrl + Space used as a shortcut for input source in Mac. To disable this go to settings -> Keyboard -> Input Sources and uncheck Select the previous source. Than syso shortcut will work.

set your perspective on default and your problem will solve.
window -> perspective ->open perspective -> other -> select default

Intellij code formatting, Java annotations on new lines

I'm using IntelliJ 12 and
It's putting my member variable annotations on the same line, which i hate! How do I setup the code formatter to keep annotations on separate lines?
thanks!

Navigate to Preferences → Editor → Code Style → Java → Wrapping and Braces tab, then locate the section Field annotations and check the option Do not wrap after single annotation.
In IntelliJ v14:

In IntelliJ 12 You can find it in setup here (bottom right):

I think all the above answers are correct but here is step by step for Mac users:
Click on "IntelliJ IDEA"
Click on "Preferences"
Go "Code Style" on the left navigation window and you will see "Java" listed below it and Click on it !
Look for the header tab "Wrapping and Braces" on the right side of Preferences window.
At this point you want to look for the item called "Do not wrap after single annotation" under "Field annotations". click "ok" and you are done !

Nothing seemed to work for me with version 2.3.3 or Android Studio. I gave up and checked Line breaks under Keep when reformatting. I just have to be very careful when I add line breaks.

Stop spacebar keypress from triggering autocomplete in Eclipse

Update
This was fixed in Eclipse 2018-12. This behaviour is still default, but can be configured off - see the accepted answer for how
I'll leave the question as it was for posterity, and for those on earlier versions of Eclipse
In Eclipse, I've enabled intellisense-style suggestions for Java by going to
Window -> Preferences -> Java/Editor/Content Assist
and setting the following
Auto activation delay (ms) -> 0
Auto activation triggers for Java -> .(abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
source = Eclipse Intellisense?
This works brilliantly, apart from one annoying problem. When I hit spacebar, the token being typed is autocompleted with whatever is at the top of the suggestions list. Fair enough, except that sometimes I'll type a class/variable name with an exact legal match, but this won't appear as the top suggestion. So when I naturally hit spacebar Eclipse inserts something completely wrong.
E.G. after typing Cookie I'll hit spacebar and get CookieMonster.
This seems like a bug, and happens often enough to be annoying, but even despite this I don't want spacebar to trigger autocomplete in general. I may want to type a variable name which hasn't been declared yet, or something similar. I want to use autocomplete as a helper tool, but my natural typing should always take priority over it.
I'd like to stop spacebar triggering autocomplete, and either fall back to using enter, or better still trigger autocomplete with a custom key not used in ordinary typing. Is any of this possible?
I've played around with all the settings in Content Assist to no avail. Googling the question just returns a bunch of results about disabling the autocomplete feature.
This issue is fixed from Eclipse 2018-12 [4.10] see the accepted answer
It's present in all prior versions, i.e. 2018-09 [4.9], Photon [4.8], Oxygen [4.7], Neon [4.6], etc..

Eclipse 2018-12 was already patched for this!
A patch for Bug 348857 was recently merged to the Eclipse project and was released as part of Eclipse 2018-12. You can download that version here.
You now have a new option to disable all insertion triggers apart from enter, which will prevent spacebar from causing autocompletion.
Simply go to Preferences... -> Java -> Editor -> Content Assist (or Window -> Preferences -> Java -> Editor -> Content Assist on Windows) and select Disable insertion triggers except 'Enter', as shown in the screenshot below:

There is a solution on the issue tracker for this.
Copy the jar in the eclipse/dropins folder. With the next restart space is diabled as autocompletion trigger.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=348857
Eclipse 12-2018 and newer: This is working natively, check Pyves answer.

Use a SDK version of eclipse
1.open Plug-ins View and find org.eclipse.jface.text, right click, choose import as Source Project. After import, you find it in your workspace.
2.In src/org/eclipse/jface/text/contentassist/CompletionProposalPopup.java
char[] triggers = t.getTriggerCharacter();
if(contains(triggers,key))
change to
if(key!='='&&key!=0x20&&contains(triggers,key))
3.Export org.eclipse.jface.text
Right click the project folder of org.eclipse.jface.text, choose export-->Deployable plugins and fragments, next, destination choose archive file, finish. Replace the one in eclipse/plugins with the one you generate.

The spacebar has been a key to select the autocomplete even in Indigo. To my knowledge, this can't be configured.
In fact, that is probably why the delay exists.
I suggest setting the delay to some optimal value that allows you to type things like private void ... comfortably without triggering suggestions for private and void. Then in case you get a suggestion because you waited too long, press Escape to abort Content Assist.

Same configuration as davnicwil, same issue, still on eclipse 4.4.
Solution: Intercept (hook) SHIFT+SPACE (press and hold) on (editor-window) eclipse and replace it with ESC,SPACE (sequence). Now you my decide between
Autocomplete+SPACE: press SPACE when autosuggestion present
just SPACE: press predefined key combination or sequence (e.g. SHIFT+SPACE)
On windows you may use http://www.heise.de/download/activaid.html (you can also use AutoHotkey, java native hook, ...)
HowTo with ActivAid:
Open Ac'tivAid, select "UserHotkeys"
click on "+", set a description
click on "short cut", press e.g. SHIFT+SPACE
Command: "{ESC}{SPACE}" (without quotes)
click "+", select eclipse editor frame, press ENTER
click OK, OK in Ac'tivAid
My config file:activAid/settings/ac'tivAid.ini:[UserHotkeys]
Hotkey11=+Space
Path11=<Send>{ESC}{SPACE}
Description11=Eclipse Shift+Space -> Esc,Space
Category11=
Application11=ahk_class SWT_Window0
You may also remap keys on non-english keyboards with "HotStrings", e.g. ö->{,ä->} etc.

Finally worked it out.
Try download this org.eclipse.jface.text.jar and copy it to your plugin folder(Typically eclipse/plugin). Do not forget to backup your own one.
Works on Eclipse Juno.
If the link doesn't work, comment on this, thanks.

In Eclipse go to Window -> Preferences -> General -> Keys and remove the binding for the command Content Assist.

You could disable Auto activation via the check box in
Window -> Preferences -> Java/Editor/Content Assist
and activate the auto-complete feature on demand. The default hotkey for this is
CTRL+Space

How can I easily fix Checkstyle errors?

Is there a way to have an IDE fix Checkstyle errors automatically without having to fix each manually?

If you are using IntelliJ, you can install the CheckStyle IDEA plugin.
Then import the CheckStyle settings into the editor, and Reformat like normal (Ctrl+Alt+L is default shortcut key).

If you're using Eclipse, yes. You can't correct all problems though. There are two ways:
Right click on the java file in Package Explorer or whatever, and select 'Apply Checkstyle Corrections'.
Click on the error in the problems view, and select 'Quick fix'. This corrects the problem.

Your question is rather vague, but I think what you're asking is if CheckStyle can automatically reformat code that it's checking to fix code layout problems that it finds.
The direct answer here is "no."
However, there are a number of "Java source code formatters" (google that, choose one) that will do what I believe you're asking for.

There is a way to do this every time you save your file but not all warnings in Checkstyle can be fixed automatically.
You can have Checkstyle generate a formatter for you by right clicking on your package in the Package/Project explorer and selecting Checkstyle->Create Formatter-Profile. This will create a new formatter called eclipse-cs [your-package-name] based off of your Checkstyle configuration. You'll find it in the "Active profile" drop-down in the formatter preferences of Eclipse.
You can then set the formatter to run each save by going to Preferences->[Language of Choice]->Editor->Save Actions. Check the "Perform the selected actions on save" and "Format source code" boxes.

I created a feature request for the Eclipse checkstyle plugin to also support quick fixes from within the code editor:
https://sourceforge.net/p/eclipse-cs/feature-requests/150/

I used jalopy. Create Tool to fix the Check style issues.
