How to Identify that SignedIn User is having particualr Role or Not in Liferay

Here i am writing example code which is used to check that the signedIn User is having the Administrator Role or Not

<%@page import="com.liferay.portal.model.Role"% ><%@page import="com.liferay.portal.service.RoleLocalServiceUtil"%>
      long companyId = themeDisplay.getCompanyId();
       Role roleAdmin = RoleLocalServiceUtil.getRole(companyId, "Administrator");

    
      if(RoleLocalServiceUtil.hasUserRole(themeDisplay.getUserId(), roleAdmin.getRoleId())) {

       }

The Above Code is to check that the SignedIn User is having 'Administrator'  Role or Not
