I'm trying to determine if a particular item in an Array of strings is an integer or not.
.split(" ")'ing an infix expression in
String form, and then trying to split the resultant array into two arrays; one for integers, one for operators, whilst discarding parentheses, and other miscellaneous items. What would be the best way to accomplish this?
I thought I might be able to find a
Integer.isInteger(String arg) method or something, but no such luck.
