Extract prepositional and phrasal verbs with regular expression

[nothinq]

I want to write a code to extract phrasal verbs and prepositional verbs. I have a data set that contains phrasal verbs. For example some are:[*]get away[*]get away with something[*]get back[*]get back at someone[*]get back into something[*]look out[*]look out for someone[*]look out for something[*]not care for something[*]keep on doing something[*]keep someone out[*]keep something from someoneEvery time a new sentence receives. Please help me to write this code with regular expression in Java.
