Refactor java code - arraylist contains with if/else

Is it possible to refactor below if/else part in elegant way? Please share your expertise and feedback.

if(onlineAreaPrioList.contains("ladies")){
            dominantOnlineArea = "ladies";
        }else if(onlineAreaPrioList.contains("kids")){
            dominantOnlineArea = "kids";
        }else if(onlineAreaPrioList.contains("men")){
            dominantOnlineArea = "men";
        }else if(onlineAreaPrioList.contains("home")){
            dominantOnlineArea = "home";
        }

Note: priority order = ladies > Kids > Men > Home

Output: values in hashmap :{men=2, ladies=2, home=2, kids=1}

values in onlineAreaPrioList :[men, ladies, home]

ComputedOnlineArea: ladies

Below are the entire code:
