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

JDK = java development kit.

Java SE = java standard edition (aka JRE)

Java EE = java enterprise edition (aka J2EE)

Update: Sun isn't well known for their clear naming conventions (Java 1.5 and Java 5.0 are the same thing, for example).

It boils down to this: If you want to run java applications, go to http://www.java.com and click on the Download button.

If you want to write java applications, go to http://developer.sun.com and wade through it until you find a download that's about 80 MB called "JDK". There are several different versions of the JDK based on what kinds of stuff you're developing (web applications, console applications, etc.).
