java - How to enable auto-complete (intellisense) in Eclipse IDE for Java

Question

I have Eclipse 2019-09 and I’m working on a Java application using some Collection classes.

I needed to see all the available methods for the Map interface but when I pressed “Ctrl+Space”, auto-complete didn’t work. “No default proposals” message came up.

How can I enable IntelliSense for Java in Eclipse IDE?

我在下面的文章中找到了解决此问题的解决方法。

Eclipse Java 自动完成功能不起作用

在 Windows 中：

Window->Preferences->Java->Editor->Content Assist->Advanced

在 MacOSX 中：

Eclipse->Preferences->Java->Editor->Content Assist->Advanced

然后，确保在顶部（默认内容辅助列表）和底部（内容辅助循环）部分中勾选以下选项。
