String length - incorrect result?

I can't understand what is wrong with the following code:

System.out.println("TEST:"+"/index/index/(\\d+)/".length());

Output: TEST:19 . But as I see there must be 20. Where is my mistake?

In java, \ is an escape character.

So: The \\ is actually a single \.

And therefore that part of the string reads like this: (\d+), which as per regex definition means "1 or more digits" :)
