I'm a Java beginner and want to learn Java and develop my simple application with the IntelliJ IDEA community.
Do I have to install OpenJDK from https://openjdk.java.net/ to develop an application with the IntelliJ IDEA community?
What I've done
I just installed IntelliJ IDEA community 2019.3.1 and I am following JetBrain documents. I thought that the IntelliJ IDEA community contains a certain JDK.
However, the document(https://www.jetbrains.com/help/idea/sdk.html) I read makes me confused. Here are sentences from the documents:
The bundled JRE is used for running the IDE itself, and it's not sufficient for developing Java applications.
You must obtain and install the standalone JDK before you start developing in Java.
IntelliJ IDEA doesn't come with the JDK, so if you don't have the necessary JDK version, download and install it.
Note that some frameworks require their own SDKs in addition to the JDK, for example, Android or Grails.
When I created my first project I saw the java version and it seems like jbr folder under the IntelliJ IDEA folder contains OpenJDK.
C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2019.3.1\jbr\bin>java -version
openjdk version "11.0.5" 2019-10-15
OpenJDK Runtime Environment (build 11.0.5+10-b520.17)
OpenJDK 64-Bit Server VM (build 11.0.5+10-b520.17, mixed mode, sharing)
However, it looks like I have to install OpenJDK to continue to develop a Java application. Do I misunderstand the document?
