Yes -- in fact, the Collections classes are largely unchanged apart from
the addition of Generics.  There is a new Queue.

There are entire new packages.  From a quick survey of the top level,

java.lang.annotation
java.lang.instrument
java.lang.management
java.util.concurrent
java.util.concurrent.atomic
java.util.concurrent.locks
javax.imageio.plugins.bmp
javax.management.* (9 packages in all)
javax.swing.plaf.synth
javax.activity

and probably more I missed.  Anything that will compile with 1.4 can
probably go in.  A lot of the language changes, I guess, are to existing
packages, while the other additions are mainly in new packages.
