JDK = Java SE && JDK != Java EE?

Question

Please confirm the above statement?

I need to know what they are referring to when they mention JDK.

Answer 1

To be more clear

Java SE -- Java Standard Edition, it happens to come in two versions: the JDK and JRE. JDK has the compiler and other tools.

Java EE -- Java Enterprise Edition is simply a standard, and a couple of libraries consisting mostly of just interfaces. While there are 'stand alone' components that can be downloaded for Java EE, alone they're of little value (again, being mostly just interfaces), and are typically bundled with the container you use to deploy or develop Java EE applications on. Plus Java EE comprises as an umbrella of many standards (JMS, JSF, etc. etc.).
