edu.stanford.nlp.math.NumberMatchingRegex

public class NumberMatchingRegex
extends java.lang.Object

This file includes a regular expression to match numbers. This will save quite a bit of time in places where you want to test if something is a number without wasting the time to parse it or throw an exception if it isn't. For example, you can call isDouble() to see if a String is a double without having to try/catch the NumberFormatException that gets produced if it is not. The regular expression is conveniently provided in the javadoc for Double. http://java.sun.com/javase/6/docs/api/java/lang/Double.html
