The difference between SDK's 1.8 and JDK_1.8.0

Question

When I open a new directory in intelliJ and create a HelloWorld.java, it asks me to define a Project SDK, and it gives me two options
1.8 (java version "1.8.0_211")
JDK_1.8.0 (java version "1.8.0_202")

One has a bunch of contents: /library/java/jvm/jdk1.8.0_211.jdk/contents/home/jre/....
The other has /Applications/IntelliJ IDEA.app/contents/home/jre/...

Are they the same?

I think the two are too similar for google to return valuable results

您不应该使用捆绑的JetBrains Runtime作为项目SDK，建议使用您的系统JDK来构建和运行您正在开发的应用程序。
