I would recommend using Jython to start -- you can do useful stuff
using your Python knowledge and use the Java libraries.  It is really
cool.

This line is a type error.

Here is a little bit of Java's magic -- the java.lang.String being
first, it's '+' operator converts the other objects to a string, then
concatenates them.

| 1. syntax/compilation error (Java is strict typed!!!)
| 2. 4aa22
| 3. 4aa4
| 4. 22aa22
| 5. 22aa4

No, but you could start with the one at http://java.sun.com.  I admit
that you won't enjoy it nearly as much as Python :-).

PS.  if you have some Java questions, email me privately because this
     list isn't about Java <wink>
