What you read in the first paragraph and in the next paragraph means the same.

“Java Runtime Environment (JRE) is an implementation of the JVM”. “JVM becomes an instance of JRE at runtime”. These are the two statements you are referring to.

They mean the same. If the second statement is confusing to understand the relationship between jvm and jre, just ignore it. If you understand the larger picture that “Java Runtime Environment (JRE) is an implementation of the JVM” is good.

Over a period, you will digest the complete relationship and difference between jre and jvm.

The picture about the implementation is good. However, I read in the first paragrapth tha JRE is an implementation of JVM and in the very next the I read the reverse of it.

Can you confirm if JRE is the implementation of JVM or JVM is the implementation of JRE?

Also, if JRE is an implementation of JVM, then I assue [JDK, JIT, Compiler] will all come under JDK.

Please confirm my understanding.
