How to use Java 8 docs in eclipse?

Question

Let’s say below is the code I’ve. When I try to hover over Calendar I can see the Java 8 documentation in Eclipse. When I mouse over getInstance, I get an error:

Calendar myCalendar = Calendar.getInstance();

The error message I got is:

Note: This element has no attached source and the Javadoc could not be found in the attached Javadoc.

Can anyone tell me what I’m doing wrong here?

You have to set the installed JRE to JDK 8 like below:

Window -> Preferences -> Java -> Installed JRE -> Edit -> Directory and selecting the JDK 8 installation folder
