Eclipse gives suggestions that starts with what I type:
But IntelliJ IDEA gives suggestions that has (in the middle or at the beginning) what I type:
I guess Eclipse Luna has the same feature (based on this presentation), but I cannot make it work. Any help?
This functionality is provided by the Code Recommenders plugin. It comes with the Eclipse Luna for Java SE, but for some reason it is not bundled in the EE version. Of course you can install it manually from the eclipse marketplace.
To activate it go to Window -> Preferences -> Code Recommenders -> Completions -> Check enable intelligent code completion. You can also select in which type of completions you are interested in. The exact feature you are looking for is called "Subwords completion processor" (and I cannot live without it :D)
I think the closest is the 'Show camel case matches' option (configured in the Preferences in Java > Editor > Content Assist).
With that enabled you have to type the first letter of each part of the name, so for 'createNamedQuery' you can type 'cNQ'

How can I prevent Eclipse from stepping into Java library code when using Step Into?
What I am used to in other IDEs (like IntelliJ) is that with Step Into you enter the methods defined by yourself or third party libraries but not the methods of the Java framework itself.
Eclipse does that and it really slows down debugging especially if you have calls to your own methods and ones defined in the Java framework in one line. You have to constantly switch between Step Over, Step Into or Step Return if you already stepped in.
You can configure the Eclipse Java debugger to not step into those bits of code by configuring a ‘Step Filter’.
Go to Windows -> Preferences -> Java -> Debug -> Step Filtering.
Check ‘Use Step Filters’.
Check the appropriate options on the screen. You can add parts that are relevant to your own codebase.
Click ‘Apply’.
More you can read about Eclipse Step Filter here
You can even create a filter for your project Package or Java class as well.
Another good link
For the People who wants to know same setting in Intellij Idea please go through below.
The reason intellij Idea do not step into java specific code is, by default Intellij Idea is enabled with below restriction. To add any other classes we can simply add it here. I added org.testng.* classes.
File->Settings-> Build, Execution and Deployment -> Debugger -> stepping
The autocomplete of eclipse is not working now and I searched for hours but I couldn't find an answer to solve it. I haven't used it for long time then the first thing after opening it was to install SWT and windows builder even though I had swing installed. What I mean is, it is may possibly be because of some conflict caused by swt and swing(I read something about a conflict but I don't if this is possible).
Strange thing is it doesn't show anything when I press ctrl+space but when I go Edit-> Content Assist -> Default(it says Ctrl+Space nearby it), it shows things needed to be shown/works as desired.
public class Dsada {
String sssss;
public Dsada(){
sss //pressing ctrl+space is not working,Edit->ContentAssist->Default works fine
}
}
The solution is not to tick/untick some stuff under Windows->Preferences->...->Content Assist-> Advanced. I checked if "ctrl+space" is hijacked by some other thing which is not and checked keyboard language which is English(Those are suggested in mkyong).
I read something about a bug but I couldn't understand. I tried to delete eclipse and re-install again but I guess some settings just stayed in the machine so that it didn't work.
This is recurring for me. I'm using Eclipse 2019-03 in Windows 10.
The steps below work for my case, and does not require a restart.
Window->Preferences->Java->Editor->Content Assist->Advanced
The following options are de-selected, and when I set them the autocomplete worked as before. No restart needed.
1. Java Non-Type Proposals
2. Java Proposals
3. Java Type Proposals
4. Java Proposals (Task-focused)
I don't know what's triggering this but it only happens after I've created a new project. Usually doesn't. It simply doesn't happen often enough for me to notice a pattern to follow up on more.
Clearly this problem occurs with a variety of causes, so review the other answers to see if they match your case.
The hot key combination ctrl+space might be conflict with other settings in system if you are using windows.
Try modify this combination like alt+/, i always use this one since the first time i knew eclipse. It works well.
Hope it works for you.
Window->Preferences->Java->Editor->Content Assist->Advanced
The following options have to be selected, then the autocomplete worked . No restart is required.
Java Proposals (must be selected, not sure the follows)
Java Non-Type Proposals
Java Type Proposals
Java Proposals (Task-focused)
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" using Ctrl+Space shortcut as default.
It is necessary to
edit 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 faced hot key problem with use Ctrl+Space. I tried to fix the issue first by Windows->Preferences->...->Content Assist-> Advanced and selected
Select the proposal kinds contained in the 'default' content assist list:
Other Java Proposals,
List item
SWT Template Proposals
Template Proposals
Type Proposals
but didn't help.
Therefore, I tried another solution. There would be multiple languages on your computer which could be eating up your Ctrl command. To solve this Go to Control Panel -> Region and Language -> Keyboards and Languages (tab) and then Change Keyboards.
You’ll see a list of languages installed – remove any that you don’t want (click the language and then click the Remove button) until you only have the ones you want left. That fixed it for me, but you can also check the Advanced Key Settings tab to make sure that none of the keyboard short-cuts that are set include Ctrl-Space.
Once you’ve done that, Ctrl-Space should work nicely!!!!
I had the same Problem on Ubuntu 14.04. The problem for me was that ibus used Ctrl+Space as a shortcut. I solved it by starting the program ibus-setup and chaning the shortcut to something else than Ctrl+Space.
Go to Windows >> Preferences » Java » Editor » Content Assist. Then Check the Auto activation triggers for java, Add this in the text box .abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
Recently, I also faced this issue. When I install neon version eclipse.
By (1) deleting respective class, (2) restoring defaults appearance and (3) restarting eclipse, solved the problem for me.
Hope it will help someone.
Go to Preferences » Java » Editor » Content Assist » Advanced. Make sure Other Java Proposals is ticked/checked.
I checked windows has no conflict of ctrl+space (of eclipse autosuggestion) with windows.
This is mere configuration issue of eclipse. reinstallation would fix it.
Thanks.
I select all the parameters in Preferences -> Java -> Editor -> Content Assist -> Advanced.
It help me and resolve the my problem.
Cltr+space work using this step.
Saving my work and restarting Eclipse solved this for me. I hadn't shut down Eclipse in a while, maybe weeks.
I had the same problem (MacOS Monterey, Eclipse 06-2022). Turned out it works with pressed fn button.
For Mac user, you can try : Preferences -> Java > Editor > Content Assist and then :
tick the field "Enable auto activation"
in the field Auto activation trigger for Java, you can input the text alphabet ".abcdefghijklmnopqrstuvwxyz"
I wrote a project in eclipse with an older version of java.
Now on a different computer but running the same codes I'm getting a whole lot of red.
This is due to Version incompatibility.
I've had my professor change the Java version from within the console window before. The code compiled just fine after he did so. I'm sure its the same case with this code.
After looking at other tutorials and google links I could only find command line approaches and #override methods. To be honest I still don't understand these.
What is the best way to change the version of a code originally written in an older code inside the eclipse console?
thanks!
In eclipse go to Window -> Preferences -> Java -> Compiler, there you can change the java versions. Hope it helps.
Ideally if we want to have two different versions of Java [say 1.6 and 1.7], then we should have two workspace defined accordingly to avoid any mixup. We can also change the Project Facets if our projects has facets that is.
In Eclipse Follow steps given below:
1) Windows -> Preferences -> Java -> Compiler and as per the image set the compliance compiler level as per your requirements.
2) Windows -> Preferences -> Java -> Installed JRE's and check if your required jre/jdk is available or not as given in image below:
3) Right Click on Your Project and go to Java Build Path and check if your required Library is available or not as per image given below:
4) Now you can edit the JRE System Library or add one by clicking on button's available on last image's right side, then a pop up as given below will open up. Here, you can change the execution environment [default values also can be set]
In myeclipse select the project -> properties -> java compiler -> there you can specify jdk version.
Easy
Download the jdk from Oracle's official website for the version you want to compile your project with.
JDK Oracle's official
create a new Java project
[
Once the project has been generated, If you select the part that says Configure JREs
By default eclipse will use the version you have installed on your system so if you don't change this configuration you will never be able to run the program with the build you need, in this case I will use jdk 1.8.
After pressing Add
5.1 And choose the option select the 3rd option in this case, called Standard VM and press Next
Now eclipse asks us to indicate the path where the libraries and other content is located in order to compile and run the program, we only have to indicate the directory where it is located.
As my goal is to run a program with the JRE 8 , I will look for the directory path where the download described in option 1 of this message is located.
As a quick example, since I just want my program to compile without worrying about anything else, I will add all the contents of my address.
Now we change by clicking on the JRE we want to compile our program, to be changed to the original default so that the new selection is executed ; and finally we press Apply and Close and Next
Press Finish to create the project
Now we have the whole project with all the necessary content to compile and run it.
Personally I think this is the quickest and cleanest way to do it ; the problem I encountered when I changed JDK is that when compiling I couldn't find the directory with the necessary components to run it, you had to download it and configure it together with the default parameters, which can cause a lot of headaches for less experienced users.
Finally, this is the version of eclipse that I am using
I hope you find this system useful, I use it to be able to run old examples that use applets , which are obsolete classes and jvm does not compile.
recently the proposals (Ctrl+Space) for Eclipse/Java stopped working, as suggested in the wiki I looked at the Preferences of Content Assist for Java, but all options are checked and still not working, any idea?
EDIT: One error is shown while trying to display proposals: Project facet grails.app has not been defined. It is used in plugin com.springsource.sts.server.tc.core.
Somehow the references to the JDK where broken, so no completions could be made!
UPDATE: Solved by going to Window -> Preferences -> Installed JREs and changing the JDK folder to the right one.
I'm stuck with Eclipse in one project and I would like to have autocompletion similar to that of IntelliJ - two major problems are:
Start typing and Eclipse would automatically suggest all possibilities
When there is item selected in dropdown list you can accept it not only with enter key but with dots, spacebars...
Go to Window → Preferences → Java → Editor → Content Assist.
In the column "Auto activation triggers for Java", enter this:
.qwertyuioplkjhgfdsazxcvbnm_QWERTYUIOPLKJHGFDSAZXCVBNM
Add any other keys you want. You're done. That answers your first query.
As far as second one goes, I think it already exists.
Take a look at Eclipse Code Recommenders [1] or Codetrails Connect [2]. They make Eclipse' code completion intelligent.
[1] http://eclipse.org/recommenders/
[2] http://marketplace.eclipse.org/content/codetrails-connect-community-edition/
I have to say NO. I moved from Eclipse to IntelliJ because of the intellisense and inability to make Eclipse behave like IntelliJ (or if you come from the .NET environment: inability to make Eclipse intellisense behave like ReSharper in .NET).
Do you HAVE TO work in Eclipse? I do 98% of work in IntelliJ, then convert the project into Eclipse project (IntelliJ can still access it) and finish it in Eclipse. Maybe you could try this solution.
Since Eclipse Juno, Code Recommenders Intelligent Java Proposals replaced the old JDT's Java Proposals.
It afford "Intelligent Code Completion" function, like IntelliJ did in a way.
You can get something useful through the link below:
http://code-recommenders.blogspot.jp/2012/07/code-recommenders-10-code-completion-on.html
There is something like that in Eclipse I think, certainly in the Eclipse Helios. When typing you press CTRL+SPACE, or when you typed variable name '.' will start auto-complete options.
Also here someone suggests to change auto complete delay settings to 0.
BTW you can also accept your selection with space bar, for sure.
EDIT:
Why not consider using NetBeans, my personal favourite. There you have an option to show auto-completion on start typing any Java Identifier Part. This would then look exactly as you want it. (in NetBeans Tools->Options->Editor->Code Completion, there in Language box select Java and finally check Auto Popup on Typing Any Java Identifier Part).
