Ctrl + Space not working for content assist on eclipse

Question

My problem is that the content assist window won\'t pop up after clicking Ctrl + Space. I checked my shortcuts and the content assist is bound to Ctrl + S

Answer 1

Earlier I was also facing the same issue : I just followed below steps :

1. Go to Windows --> Preferences --> Java --> Editor --> Content Assist --> Advanced --> select all Java & Java Type Proposals.

2. Click on Apply and close it.

3. Restart the eclipse.
