Java: Split string when an uppercase letter is found

Question

I think this is an easy question, but I am not able to find a simple solution (say, less than 10 lines of code :)

I have a String such as \"thisIs

Answer 1

This regex will split on Caps, omitting the first. So it should work for camel-case and proper-case.

(?<=.)(?=(\\p{Upper}))

TestText = Test, Text
thisIsATest = this, Is, A, Test
