Java as of 1.5/Java 5 ( collections, generics, many others ).
Collections came in with JDK 1.2 did they not?
Yes.
Generics came in 1.5 IIRC.
Swing came in 1.3 with a taste in 1.2
assertions came in 1.4
enums came in 1.5

Java SE 1.4 brought in NIO.
Java SE 5 also introduced auto(un)boxing, vararg calls, annotations, for-ea=
ch, new API calls, 'switch' on enum values, and perhaps most important, the=
new memory model (/happens-before/, new 'volatile' semantics). It also fi=
xed a bug where class initialization was occurring upon reference to the 'c=
lass' class member. Java SE 5 is no longer supported.
Java SE 6 introduced the inbuilt Compiler API, allowed '@Override' to apply=
when the supertype is an interface, enhancements to JDBC (including some t=
hat broke backwards compatibility), StAX, improved JAXB, SwingWorker, and v=
arious performance improvements.
Java SE 7 brings us "waka waka" (here I make fun of another poster's name f=
or the diamond operator), 'switch' on 'String' values, resource disposal, n=
ew numeric literal syntax, multi-'catch', compressed 64b pointers and other=
JVM magic, and a mess of API improvements.
