Eclipse Intellisense?

Question

How do I tell Eclipse to automatically make suggestions as I type? I'm looking for a Visual Studio Intellisense-like feature with Resharper.

Currently I have to press CTRL+Space each time.

Answer 1

You don't have to press CTRL * space but maybe the delay is too big or you don't like the trigger (default is '.'). Go to

Window -> Preferences -> Java/Editor/Content Assist

And change the settings under Auto Activation to your likings.

If this does not work for windows users then see this answer.

Answer 2

I've get closer to VisualStudio-like behaviour by setting the "Autocomplete Trigger for Java" to

.(abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ

and setting delay to 0.

Now I'd like to realize how to make it autocomplete method name when I press ( as VS's Intellisense does.

Answer 3

Tony is a pure genius. However to achieve even better auto-completion try setting the triggers to this:

ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz =.(!+-*/~,[{@#$%^&

(specifically aranged in order of usage for faster performance :)

Answer 4

If it's not working even when you already have Code Assist enabled, Eclipse's configuration files are probably corrupt. A solution that worked for me (on Eclipse 3.5.2) was to:

1. Close Eclipse.
2. Rename the workspace directory.
3. Start Eclipse. (This creates a new workspace directory.)
4. Import (with copy) the Java projects from the old workspace.

Answer 5

I once had the same problem, and then I searched and found this and it worked for me:

I had got some of the boxes unchecked, so I checked them again, then it worked. Just go to

Windows > Preferences > Java > Editor > Content Assist > Advanced

and check the boxes which you want .

Answer 6

d3dave's answer is cool. However theGreenGarbage mentioned an issue about it which I too find rather annoying. So here's one that doesn't immediately suggest something after '=' sign and when typing blank space:

ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz.(!+-*/~,[{@#$%^&

What I did was simply remove the space and '=' chars from the array :)

Alternatively if you want suggestions when typing blank space, but not after '=' sign:

ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz .(!+-*/~,[{@#$%^&
