vim regex increment all numbers by 1

Question

I have a prepared statement in java that i am adding an argument to the front of. Long story short, I have to take a ton of set methods and increment their first argument by 1.

I'd like a quick way to do a search and replace matching all numbers, and then increment them by one.

Answer 1

Figured it out.

%s/\d\+/\=(submatch(0)+1)/g

Answer 2

The only regex you need to know is \d.

:g/\d/exe "normal! \<C-A>"
