Script Shell - Command nohup - "&" - Doubts

I don't exactly know What this Next line does:

Command Line:

nohup java -Dprocess=$PROCESS -classpath $CLASSPATH batch_wtq &

I mean i have a little idea about -NOHUP- command but i don't know what the ampersand (&) does.
I would like someone help me with a description about the whole command line.

nohup means "no hangup", meaning that the process will still run after you log out of the shell. The amptersand & means the process will run in the background and so you'll get back to your shell prompt after you run that command.

The -Dprocess is a Java property being passed in to the Java program with the environment variable PROCESS. Likewise, the classpath is being set to the environment variable CLASSPATH. The Java class with the public static void main method is batch_wtq, which should be on the classpath somewhere.
