My son is 15 years old and his behavior is out of control. What do I do and what could this mean?

My son is 15 years old and has been doing things like breaking household items for no apparent reason, he throws rocks at kids in the freshmen’s in his school, and has now been suspended for giving his art teacher a black eye and when he was asked why he said because he didn’t like the way he painted. What should I do and what could this mean for my son?
