Difference between java and java 1.5?

Answer 1

Nothing unless the "java" your talking about is coffee.

The sorta answer is that java is a programming language while java 1.5 is the 5th release of the language

there are i believe 7 public versions. (maybe 6 but I'm not sure.)

Java 1.1, 1.2, 1.3, 1.4, 1.5, 6, & 7. (6 & 7 aren't java 1.6 and 1.7 they are 6 & 7. It drives every one crazy.)

If your learning java you should be studying java 6 or 7.

6 is the better of the two if you ask me since:

you'll be learning the basics of java,

its more likely to be used in a school, or business environment,

and if for some reason you do need to learn 7 then it's easier to switch over from 6 to 7 then 7 to 6

7 has new stuff that if you don't know about it wont hurt you how ever you plan on using said items when programming in 6 your program wont run correctly if at all.

The reason while not everyone is at java 7 yet is because they have to validate it to make sure there are no security leaks and/or programs breaking.
