Java String.split() Regex

Question

I have a string:

String str = \"a + b - c * d / e < f > g >= h <= i == j\";

I want to split the string on all of the operators

Answer 1

Can you invert your regex so split by the non operation characters?

String ops[] = string.split("[a-z]")
// ops == [+, -, *, /, <, >, >=, <=, == ]   

This obviously doesn't return the variables in the array. Maybe you can interleave two splits (one by the operators, one by the variables)
