i not getting updated list method passed references

    list<person> beans = new arraylist<person>();     boolean alreadypresent = ispersonpresentonsolr(solrserver, beans);      // beans.size() 0     boolean ispersonpresentonsolr(solrserver solrserver, list<person> beans)    {     queryresponse response   = solrserver.query(solrqry);                     beans = response.getbeans(person.class);      //beans.size()  5    }

you should not do

beans = response.getbeans(person.class); // lost reference of object. c++ way, //but not works java

you should do

list<person> newbeans = response.getbeans(person.class); beans.addall(newbeans);
