Eclipse Enable autocomplete content assist

Question

How can I enable autocomplete in Eclipse  I can t find it

User · Answer

If you would like to use autocomplete all the time without having to worry about hitting Ctrl + Spacebar or your own keyboard shortcut, you can make the following adjustment in the Eclipse preferences to trigger autocomplete simply by typing several different characters:

Eclipse > Preferences > Java > Editor > Content Assist
Auto Activation > Auto activation triggers for Java
Enter all the characters you want to trigger autocomplete, such as the following:

abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ._

Now any time that you type any of these characters, Eclipse will trigger autocomplete suggestions based on the context.

I am not sure if this has to be explicitly enabled anywhere  but for this to work in the first place you need to include the javadoc jar files with the related jars in your project  Then when you do a Cntrl Space it shows autocomplete and javadocs

If you are only unfamiliar with the auto-complete while typing syntax or inbuilt methods in the eclipse you can simply type the desired syntax or method name and press Ctrl Space that will display the list of desired options and you can select one of them   If the auto-complete option is not enabled then you have to check your settings from Windows menu -  Preferences -  Java -  Editor -  Content assist

By default in Eclipse you only have to press Ctrl-space for autocomplete  Then select the desired method and wait 500ms for the javadoc info to pop up  If this doesn t work go to the Eclipse Windows menu -  Preferences -  Java -  Editor -  Content assist and check your settings here
