When I am typing Eclipse does not automatically shows content assist, but only after I press Ctrl + Space.
I used to type class name and Eclipse gave good proposals automatically.
But now it is not working.
Go to, Window >> Preferences >> Java >> Editor >> Content Assist >> Auto activation triggers for Java, and enter .abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
, this will trigger the auto activation for class names, methods, etc.
