Java RegEx explanation needed

[heatblazer]

Hello, everybody. Since I came from Perl which is known for it`s monstrous powerful RegEx, I want to know how can I read regexes in Java. Let`s say:

/(-){0,1}[0-9]((\.)&[0-9]){0,1}/

which must match any number real or whole negative or positive. I want a simple example that explains:
matching a whole or real number either negative or positive. That`d be sufficient.
Thanks.
