Eclipse Intellisense?

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.

Solution 1:

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.

Solution 2:

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.

Solution 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 :)

Solution 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:

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

Solution 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 .
