I am new to IntelliJ and recently updated to IntelliJ-2016.3.
In the editor for Java code, it shows the method signature upon usage. How do I disable this feature?
Here's an example of a method's signature and its call site:
Method call:
This behavior was not there in 2016.1.4 version. I am seeing this after update.
Any help is appreciated!
Untick the bottom option Show parameter name hints
Right click on the hint, then on Disable:
I find it helpful to use a shortcut such as P + shift + command to toggle parameter type hinting as needed. I don't want it disabled entirely.
open preferences
click Keymap
filter by parameter
double click on Toggle parameter name hints
enter key combination ie, P + shift + command
Apply and Ok
Now the key combo will toggle hints for you.
From the what's new page:
Parameter hints
The editor now shows parameter hints for literals and nulls used as method arguments. These hints make code much more readable.
If you find hints redundant for a certain method, you can tell the IDE not to show hints for this method. To disable hints completely, uncheck Settings → Editor → General → Appearance → Show parameter name hints.
(emphasis is mine)
In latest version you can find it under Settings → Editor → Inlay Hints
Others have already answered this, but here is a way of finding it without jumping into menus.
Try hitting ⌘ + Shift + A on Mac or CTRL + SHIFT + A on Linux and type the Show parameter name hints into the search bar.
As of 2022, it's been renamed to "inlay hints"
You can disable it by pressing shift + shift, then type inlay hints and then disable it.
⌘ + Shift + A
Type Inlay Hints
Make sure that the language of your choice has Types set up properly!!! Here's an example for Kotlin:
As on 2022 (WebStorm 2022.1.2), the option is under the Editor → Inlay Hints. Uncheck the parameter names checkbox.
For Intellij IDEA 2022
Editor -> Inlay Hints -> Code vision -> Usages , Uncheck this

currently in eclipse if i want to generate a constructor or getters/setters i
go the class name right click on that ->source->access the right Generation option
while in the android studio we have a convenient and fast shortcut to do that
i just need to press CMD+N anywhere in the page to open the generate dialog
is there an eclipse shortcut available that is equivalent to that ?
Press Alt+s then type c for constructor, r for set/get s for
toStringetc..
You can go to Windows -> Preferences -> General -> Keys to map this action to a shortcut of choice.
This is how to do it:
There isn't one by default, but if you wish you can modify the mappings and add a shortcut. You can do this by going to window->preferences->general->keys
Go in window -> preferences -> general -> keys
Type generate in the search bar.
Find Generate Getters and Setters
Click on the binding field and hit your custom shortcut (here : Ctrl + Alt + Shift + S).
Go to Windows -> Preferences -> General -> Keys or you can take the list of shortcut in this site 25 Eclipse Shortcut Keys
You can also use the quick fix : Ctrl + 1.
When you have an error, it allows you to resolve this error. and when the cursor is on a variable, it allows you to generate getter and setter.
If you want an empty construtor, just type Ctrl + space somewhere in your class.
Short answer: no.
But google shows a number of pages on how to do it, e.g. https://wiki.eclipse.org/FAQ_How_do_I_provide_a_keyboard_shortcut_for_my_action%3F
A lateral solution, but you may be interested to check out Project Lombok (I don't use it myself at the moment.)
As I remember ,alt + insert do this.
The answer by #Rustam put me on the right path.
but since his answer is based on windows version of eclipse and I am using mac i was unable to confirm it .
i added this answer to provide additional data for any one using the MAC version of eclipse
ALT + CMD + S will bring the source menu after that you can select the correct generation option
In Intellij IDEA, how to search a string or a keyword in all project files as we can do in Eclipse by Ctrl+H command?
To search in workspace you can use Ctrl+F.
To find in path Ctrl+Shift+F is useful
Ctrl + Shift + F to search across the project
Ctrl + H = "Type Hierarchy" view = shows a tree of parent and
child classes of this class.
Ctrl + Shift + A = "It does a search as you type through all the commands
in intellij. Not only that but when you find the command you want it also
displays the corresponding shortcut key next to it!"
https://www.jetbrains.com/idea/help/keyboard-shortcuts-you-cannot-miss.html
Hope this will helpful to you !
For navigating to a class by name (Ctrl+N)
The Shortcut you are searching for is Ctrl+Shift+H
In the Find In Path dialog box displayed, specify the following options:
The text to find.
Type the text explicitly, or specify a pattern using a regular expression, or select a previously used piece of text or a pattern from the recent history drop-down list.
If you specify the search pattern through a regular expression, use the $n format in back references (to refer to a previously found and saved pattern).
Search scope (project , module or directory).
Search options (case sensitivity, whole words, and regular
expressions).
Then Click Find.
Hope this is helpful.
Ctrl+Alt+I or Ctrl+Alt+L in IntelliJ IDEA
Ctrl+Shift+F in Eclipse
You can try the above solutions and also the link which is mentioned in here for more useful shortcuts with intellij
Ctrl + Shift + N

well I've seen in Tips & Tricks of Eclipse that it's possible to get a variable name generated by eclipse by clicking Ctrl + Space. However I'm getting empty suggestions. Fors instance I'm typing this and click ctrl + space:
private Color
And I am supposed to get some name suggestions on it? All I'm getting is an empty list of suggestions. So what's turned off? Any idea?
Thanks in advance.
This is what I want to achieve:
I believe you are trying to get variable name e.g. color after private Color where Color is you class i.e. private Color color. I see that working in my eclipse.
To verify your settings, go to below settings and verify as they look good to you.
Windows -> Preferences -> Java -> Editor ->Content Assist
and
Windows -> Preferences -> Java -> Editor ->Content Assist -> Advanced
This is the default behavior after entering a Java type and a space, and then pressing CTRL+Space to activate auto-complete. For example, if you enter:
private Color
then activate auto-complete it will suggest some variable names for you.
An easier way than having to press CTRL+Space all the time is to change the characters which automatically activate auto-complete. I find it very useful to have all characters which could possible be variable names to activate auto-complete. Try having ._abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ as Auto activation triggers for Java found in Preferences -> Java -> Editor -> Content Assist:
This way you can achieve how Visual Studio handles auto-complete.
Goto Window -> preferences -> java -> Editor -> content Assist ->Advances -> Select all the check boxes. DONE :)
private? It looks like you're creating something new.. eclipse cannot suggest in this case.
Autocomplete is for existing variables/functions/classes/etc.
I tried them one after the other and found out that the correct one is:
Windows -> Preferences -> Java -> Editor ->Content Assist -> Advanced: check Word Proposals
In Eclipse, it can get a variable name that you already made.
For example,
int awesomeVariable;
awesomeVariable = 50;
int superVariable;
superVariable =
If I press Ctrl + Space after that =, it would generate some things that it could fill in. For example, it might suggest awesomeVariable. Basically, it doesn't generate a name for you, it just auto-completes with things you have already created.
Ctrl + Space is maybe shortcuts of IM, so it is covered, I suggest you change the shortcuts of this function, for example: Alt + /,
if you don't know how to change shortcuts, please see the following steps:
click Ctrl + Alt + L twice,
find "Content Assist",
change Binding value to you like shortcuts(cannot same the other shortcuts),
click Apply button.
Thanks for everyones time and help. :)
I finally found it and the answer to this was that in my case the "java.awt.Color" wasn't imported and eclipse doesn't work on this one if it's not imported.
So it does suggest the name for you if your file had imported the class already, but if it hadn't it won't work.
I guess it makes the whole function pretty useless, but unfortunately that's how eclipse works. :/
it just suggesting you can also declare the variable by that name..it just helping you because it was a tool write..nothing to worry about that..you can give your own name as you like kk..
import Color Class to your class: import java.awt.Color;
Say I type "sout", the intellisense should expand it to "System.out.println()". Is there a way to adding such templates?
The feature is called "code templates" in Eclipse. You can add templates with:
Window->Preferences->Java->Editor->Templates.
Two good articles:
Don't write the code, generate it
Custom Templates
Also, this SO question:
Useful Eclipse Java Code Templates
System.out.println() is already mapped to sysout, so you may save time by learning a few of the existing templates first.
Type "Sysout" and then Ctrl+Space. It expands to
System.out.println();
Type syso and ctrl + space for System.out.println()
type "syso" and then press ctrl + space
OR
type "sysout" and then press ctrl + space
This is one more option: go to Windows > Preference > Java > Editor > Content Assit. Look in "Auto Activation" zone, sure that "Enable auto activation" is checked and add more charactor (like "abcd....yz, default is ".") to auto show content assist menu as your typing.
I've been Eclipse-free for over a year now, but I believe Eclipse calls these "Templates". Look in your settings for them. You invoke a template by typing its abbreviation and pressing the normal code completion hotkey (ctrl+space by default) or using the Tab key. The standard eclipse shortcut for System.out.println() is "sysout", so "sysout" would do what you want.
Here's another stackoverflow question that has some more details about it:
How to use the "sysout" snippet in Eclipse with selected text?
Step 1 -> Top apple icon -> System preference -> keyboard -> Shortcut>spotlight -> uncheck.
Step 2 ->Eclipse -> General -> keys -> search -> content Assist ->
Binding (cmd button + space) -> Apply&close.
In a Visual Studio, you would use Ctrl+L, whereas in Eclipse I am forced to select a line or, if it is empty, go the beginning of the line before clicking delete/backspace.
Is there a quick shortcut? Thanks!
Ctrl + D
From Help->Key Assist... there are all kinds of useful keyboard shortcuts for Eclipse.
For Mac users: ⌘ + D
In the future, if you need to quickly find a keyboard shortcut for something simple, just hit Ctrl+Shift+L.
Ctrl + D should delete the line.
You can reassign the Delete Line command to your favourite hotkey.
Window->Preferences
General->Keys.
Now type "Delete" and reassign the filtered command.
if your are using MAC then it is
command + D => ⌘ + D
To quickly find shortcuts, hit Ctrl + L, Ctrl + L (Ctrl+L twice), then type something approximating what your command does in the filter text for the key assignments. This works pretty well for most shortcuts, although it can be a bit tricky for some where the name of their menu assignment bears no relation to that of their command in this list (for instance, Team->Revert to base appears in the keys list as 'Replace with latest from repository'), so sometimes a little lateral thought is required :-) If no shortcut exists, it's easy to add one in the keys dialog.
And if you want it as a list to take a print or something, here is a link to the eclipse shortcut pdf.

press Ctrl+Shift+L TWICE and press TAB then you can type to find your shortkeys
