android - Java "get{Object}" method naming convention -

which of following compliant java guidelines?

observable<list<account>> getaccounts(string userid);  observable<list<account>> getaccountsforuser(string userid); 

i don't want start debate, i'm looking document stating guidelines. don't think matters, i'm using previous snippet of code inside android project.

i'd if there 1 type of model has "accounts" use

observable<list<account>> getaccounts(string userid); 

if there multiple models have accounts, makes sense define method in more detail using:

observable<list<account>> getaccountsforuser(string userid);
