How to use a regular expression in Java to validate if 2 identical, consecutive numbers exist

Hello again - I need to do a password validation in Java checking whether or not a string has 2 consecutive, identical characters.  I would like to use a regular expression do this.  I have a working solution in Javascript, but haven't gotten it to work in Java yet.  Here is my Javascript code:

var doesConsIdentCharExist       = /(.)\1/.exec(password);

This matches irrespective of whether the character is at the beginning or end or middle and whether
it's alphabetic, numeric or special.

You're welcome!

Follow some simple rules when converting from a JavaScript RegEx to a Java one.

1. Escape all \ with \\
2. Start and end with .*
3. Use String#replaceAll() method to replace text.

Good Luck!
