There has never been a JDK called "3" or "3.0". Are you asking about the difference between "5" and "5.0"? "5.0" is a way of talking specifically about one release (as opposed to, say, the next one -"5.1"-, should that ever come be), while "5" would mean "all JDK 5.x releases".

Sun thinks it's fun to confuse the whole world with inconsistent JDK version numbers. They actually think it's useful to give something the version number 1.5.0 and 5.0 at the same time.

Read this, for example: Version 1.5.0 or 5.0?

Likewise, they are doing strange things with the "2" in the name of the JDK / JRE. Currently we are talking about "J2SE", "J2EE" etc., but in the future they will be dropping the "2", so we'll have "JSE" and "JEE".
