Change the code for infos you have.You can write person.cs instead of map.

public class PersonInfo{

    private Map<String, String> exampleData = new HashMap<String, String>() {{ 
        put("Jack", "35"); 
        put("Ryan", "24");
    }};

    private String searchString; 
    private String person;

    public void updatePerson(AjaxBehaviorEvent event) {
        person= exampleData.get(searchString);
    }

    public String getSearchString() {
        return searchString;
    }

    public void setSearchString(String searchString) {
        this.searchString = searchString;
    }

    public String getPerson() {
        return person;
    }

}


}
