java - How do I refactor ArrayList<MyClass> into MyClassLIst? -

i have project in eclipse (kepler), , using using following in quite few places

ararylist<person> person; 

and

person = new arraylist<person>(); 

and methods return , take

 arraylist<person> 

is there easy way refactor arraylist in personarraylist extends arraylist?

i able have methods like

arraylist<people> getallwithphonenumber(string phonenumber) {  } 

update: underlying reason question based on following need. maintaining list of people objects in arraylist, decided needed have functionality such being able search list , return 1 or more people based on properties. original plan create new class extends arraylist , add methods class.

my current thinking create people class has arraylist rather extending arraylist

i think right approach. please comment if going down bad path.

thanks comments; helped me think thru (i amateur @ stuff, fun learning)

class personarraylist extends arraylist<person>{}
