The Java SDK includes the JRE.
SDK: Software Development Kit. This includes everything you need to write Java programs.
JRE: Java Runtime Environment. This includes everything you need to run Java programs.
Java 1.5.0 is newer than Java 1.4.2. You only need 1.5.0. |

Yes, JDK is usually short for Java Development Kit. Haven't heard that term in ages, though. I've mostly heard Java SDK recently.
No, both do not need to be downloaded.
People would have just the JRE because all they care about is running Java programs, like applets on web sites. Far fewer people (but still a substantial number) actually write Java programs. |

People get JRE because most people want to have a java compatible browser (use java applets and that kind of thing) while not so many people program in Java (SDK).
Isn't SDK 5.0 the same thing as SDK 1.5.0? You only need to download the newest version, at all.
*edit* Dang, I didn't refresh in a while. Oh well. |

Yes. Sun sucks at naming things. |

It was a significant change from 1.4, and (I've read this on their site) that's the new way of naming the kits (Java SDK 5.0 is the name, Java SDK 1.5.0 is th technicall version). At least that's may understanding, and the Lord knows I've been wrong before...oh so many timea....  |

no the 5.0 thing started out with version 1.5.x
in addition to that, things have changed from 6.0 onwards...
it is no longer J2SE 6.0, but Java SE 6.. simpler? yes i thought so too. |
