autocomplete eclipse code example

Example 1: eclipse autocomplete

Eclipse > Preferences > Java > Editor > Content Assist

._abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ

Example 2: eclipse auto suggestions no keyboard

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.
