Wrong!  JDK 1.0.x, 1.1.x, 1.2.x, 1.3 and 1.4 are all vastly different.
(SDK =3D=3D JDK, just marketing terminology) When it comes to Sun/Java
versioning, think of the first number as a constant, the second as the
major number and the third as the minor number.  The _language_ itself
changed between 1.0 and 1.1, and the library changed majorly between
1.1 and 1.2.  1.2 and 1.3 are fairly similar, and I recently learned
that 1.4 adds more stuff to the standard library.

No, swing was created after the 1.1.x releases.  You can separately
obtain an (old) version of swing which will work with jdk 1.1.8, but
1.1 is soo ancient and obsolete that I don't recommend starting with
it.  Use at least 1.3, or 1.4 if your OS is supported.  JDK >=3D 1.2
includes swing as part of the standard library.
