Java JDK, SDK, SE?

Question

If you could answer these questions or help me out a little with clarity, it will be greatly appreciated:

---

• Is Java 7 just Java SE 7? and Java 6 is Java SE 6?

Answer 1

Answer 1: SE stands for Standard Edition. It is mostly like for every JRE nowadays to be in Standard Edition, so you can take Java 7 and Java SE 7 as the same thing.

Answer 2: JDK stands for Java Development Toolkit. Java SE is the technology, and JDK is the set of tools for developing in that technology.

Answer 3: Technically yes. Actually, you're most likely to see "JDK 1.6" alongside "Java 6", "JDK 1.7" alongside "Java 7" and so on.

Answer 4: Same as 3, I guess.

Answer 5: Java's Software Development Kit equals Java's Development Kit, so yes.
