Answer 1

You need to open the File | Project Structure | SDKs File | Project Structure | SDKs File | Project Structure | SDKs , go to the Sourcepath , and attach this JDK's source code file (often named src.zip). See the detailed steps/images here: https://mkyong.com/java/how-to-attach-jdk-source-code-to-intellij-idea/

The source code file (src.zip) often comes from $JAVA_HOME/lib/src.zip and $JAVA_HOME/src.zip from your downloaded JDK 1 .

Another easier way is to go to File | Project Structure | SDKs File | Project Structure | SDKs File | Project Structure | SDKs , click the + icon to download one JDK which would configure the sourcepath by default.

The Documentation paths mentioned by @Müseyib Ələkbər is for Quick Documentation popup. See https://www.jetbrains.com/help/idea/sdk.html#configure-external-documentation

Go "File->Project Structure" and add the source for the documentation
