When entering eclipse Java source code, auto activation triggers

Automatic trigger completion of eclipse

One of the advantages of using eclipse is the auto-completion trigger function when inputting Java source code. However, it works after entering "." In normal operation, but is there a setting method when you want to make more use of it?

Setup steps

eclipse> Window (W)> Settings (P)

Set from Java> Editor> Content Assist> Auto Enable

--Automatic activation delay (milliseconds): 0

`Default value: 0 ⇒ changed to the following`

--Java auto-activation trigger :.

`Default value: ⇒ Change to the following`


.abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_

--Javadoc auto-activation trigger: @ #

`Default value:@#⇒ You can leave it as it is`

@#

After clicking "Apply and Close", let's enter the Java source code.
