How to Fetch all Permission of Role in Liferay 7

Question

I want to fetch all permission of a particular role, I tried using ResourcePermissionLocalServiceUtil but it only fetches permission which is inside role.

System.out.println("userGroupGroupRole:::" + userGroupGroupRole);
List<ResourcePermission> listOfPermission = new 
ArrayList<ResourcePermission>();
for (UserGroupGroupRole uggrole : userGroupGroupRole) {
    listOfPermission
        .addAll(ResourcePermissionLocalServiceUtil.getRoleResourcePermissions(uggrole.getRoleId()));

    System.out.println("Title::" + uggrole.getRole().getTitle(locale));
    System.out.println("Site:::" + uggrole.getGroup().getGroupKey());
    System.out.println("user-group:::::" + uggrole.getUserGroup().getName());
}

System.out.println("listOfPermission::" + listOfPermission);

This Way we can fetch all permission

PortletConfigurationPermissionsDisplayContext portletConfigurationPermissionsDisplayContext = new PortletConfigurationPermissionsDisplayContext(
            request, renderRequest);

    Resource resource = portletConfigurationPermissionsDisplayContext.getResource();

    if (Validator.isNotNull(portletConfigurationPermissionsDisplayContext.getModelResource())) {
        PortalUtil.addPortletBreadcrumbEntry(request,
                HtmlUtil.unescape(portletConfigurationPermissionsDisplayContext.getSelResourceDescription()),
                null);
        PortalUtil.addPortletBreadcrumbEntry(request, LanguageUtil.get(request, "permissions"), currentURL);
    }
    System.out.println("Resource::" + resource);

    boolean role_a_hasPermissionToView = false;
    List<Role> allRoles = RoleLocalServiceUtil.getRoles(0, RoleLocalServiceUtil.getRolesCount());
    //System.out.println(allRoles + "-all roles");
    for (Role role : allRoles) {


                System.out.println("---------------------------------------");
                String rolename = role.getName();
                System.out.println("Primary Key::" + role.getPrimaryKey() + "----Role Name::" + rolename);
                System.out.println("---------------------------------------");

                List<String> currentIndividualActions1 = new ArrayList<String>();
