Eclipse – Disable content assist in Eclipse

content-assisteclipse

How do you disable content assist in Eclipse?

I do not mind allowing it to come up when I press ctrl & space, but I do not like how it automatically comes up as I am typing. It just messes me up. For instance it, I would end up scrolling through the options when I just want to go up a line. It is getting tedious having to press escape whenever it decides to pop up.

I have found the page in the preferences for it, but I cannot seem to find out how to disable the auto-pop-up.

EDIT: I am using the application for android development. I have already disabled "auto-activation" for both Java and XML, but it does not seem to have an effect. The window will still pop up automatically.

EDIT2: I tried restarting the program after making the changes, but it still had no effect. I made sure that the option changes were still in effect, and they were still in effect.

This Eclipse3.6 Help page on Content assist can help (it is for C++, but the same idea applies for Java on the Java > Editor > Content Assist preference page.):

The idea is to disable what triggers the content assist.

Eclipse – How to you speed up Eclipse

The three most influential factors for Eclipse speed are:

Using the latest version of Eclipse (2020-06 as on 26 June 2020)
Note that David Balažic's comment (July 2014) contradicts that criteria which was working six years ago:

The "same" workspace in Indigo (3.7.2) SR2 loads in 4 seconds, in Kepler SR2 (4.3.2) in 7 seconds and in Luna (4.4.0) in 10 seconds. All are Java EE bundles. Newer versions have more bundled plugins, but still the trend is obvious. (by "same" workspace I mean: same (additionally installed) plugins used, same projects checked out from version control).

Launching it with the latest JDK (Java 14 at the time of writing, which does not prevent you to compile in your Eclipse project with any other JDK you want: 1.4.2, 1.5, 1.6 older...)
```
  -vm jdk1.6.0_10\jre\bin\client\jvm.dll
```
Configuring the eclipse.ini (see this question for a complete eclipse.ini)
```
  -Xms512m
  -Xmx4096m
  [...]
```

The Xmx argument is the amount of memory Eclipse will get (in simple terms). With -Xmx4g, it gets 4 GB of RAM, etc.

Note:

Referring to the jvm.dll has advantages:

Splash screen coming up sooner.
Eclipse.exe in the process list instead of java.exe.
Firewalls: Eclipse wants access to the Internet instead of Java.
Window management branding issues, especially on Windows and Mac.

Dec. 2020, Udo conforms in the comments

From version 4.8 (Photon) an up there was a steady speed gain after each version.
The main platform was optimized every release to load faster, enable more features for the dark theme and to add more features for newer Java versions for the Java development tools.
Especially with-in the last 3 versions the startup time was increased a lot. There should be a significant increase in start-up time with the newest version of Eclipse 2020-12.

In my experience it started a lot faster with each new version.
But: There are still plug-ins which do not follow the new way of using the Eclipse API and are therefore still slow to start.
Since the change to Java 11 as the minimum runtime version starting from Eclipse version 2020-09 at least the core system uses the newer features of the JVM. It is up to the providers of the other plug-ins to upgrade to newer APIs and to use the full power of modern CPUs (e.g. concurrent programming model).

Java – ‘Must Override a Superclass Method’ Errors after importing a project into Eclipse

Eclipse is defaulting to Java 1.5 and you have classes implementing interface methods (which in Java 1.6 can be annotated with @Override, but in Java 1.5 can only be applied to methods overriding a superclass method).

Go to your project/IDE preferences and set the Java compiler level to 1.6 and also make sure you select JRE 1.6 to execute your program from Eclipse.
