Detecting String/integer next to any character?(java)

Question

I want a way to detect some strings / integers next to a specific character. for example
34+56-90
I want my code to detect the 56 as it id next to + sign.
Also it would be helpful if I can detect previous integer also.

Like Niek said, the split function using a regular expression seems appropriate for your problem : it will split a given string based on the regular expression you specify.
Regular expressions are a very useful and powerful tool. Basically, it is a string that defines a set of rules for use with other strings (when searching, splitting, deleting etc.)
