Hi all.
The explanation said:

The modular structure of the JDK implements the following principles:
1. Standard modules, whose specifications are governed by the JCP, have names starting with the string "java.".

2. All other modules are merely part of the JDK, and have names starting with the string "jdk.".

Who maintains the JDK modules? Is it Oracle? Are JDK modules consistent across different implementors(OpenJDK, OracleJDK, Amazon Corretto ...)?

Yes, JDK modules are managed by the provider of the JDK. No, jdk modules may not be consistent across jdk implementations and should not be relied upon.

Hi, i have a question about the option:
JDK is divided into a set of modules that can be combined at compile time, build time, and run time into a variety of configurations.

I didn't check this option as correct because i didn't know that the modules can be combined at run time, can someone give me an example?

For the details on this topic, you will need to go through this: http://openjdk.java.net/jeps/220

I think I (more or less) know how to combine modules at compile time/run time. But how can it happen during build time?

For the purpose of the exam just assume that you can.
But if you still want to go into details, may be this will help: http://hg.openjdk.java.net/jdk/jdk/raw- ... lding.html
