How can tokenize this string in java?

Question

How can I split these simple mathematical expressions into seperate strings?

I know that I basically want to use the regular expression: \"[0-9]+|[*+-^()]\"

Answer 1

You only put the delimiters in the split statement. Also, the - mean range and has to be escaped.

"578+223-5^2".split("[*+\\-^()]")
