Another feature added in Sprint ’15 is the ability to access Address and Geolocation Compound Field using Apex. I will explain the new feature with example below –
First I will create a new field of type Geolocation in the User object as shown below –
Now I will write the below code to access Location and Address details from User as below –
public class UserLocation {
public List<Double> getUserGeoLocation(String userName){
User anUser = [Select Id, Location__c from User where Username = :userName LIMIT 1];
Location location = anUser.Location__c;
List<Double> geoLocation = new List<Double>();
return geoLocation;

public Address getUserAddress(String userName){
User anUser = [Select Id, Address from User where Username = :userName LIMIT 1];
return anUser.Address;
I will write the test class also to test the functionality as shown below –
public class UserLocationTest {
@testSetup static void setup() {
User userToCreate = new User();
//Add required information
userToCreate.FirstName = 'Sudipta';
userToCreate.LastName = 'Deb';
userToCreate.Alias = 'sdeb';
userToCreate.Email = '';
userToCreate.Username = '';
userToCreate.CommunityNickname = 'Sudipta.Deb';
userToCreate.ProfileId = '00eB0000000F8dB';
userToCreate.TimeZoneSidKey = 'America/Denver';
userToCreate.LocaleSidKey = 'en_US';
userToCreate.EmailEncodingKey = 'UTF-8';
userToCreate.LanguageLocaleKey = 'en_US';
//Adding the information Geolocation
userToCreate.Location__Latitude__s = 22.5667;
userToCreate.Location__Longitude__s = 88.3667;
//Adding the Address information
userToCreate.State = 'West Bengal';
userToCreate.City = 'Kolkata';
userToCreate.PostalCode = '12345';
userToCreate.Country = 'India';

insert userToCreate;

static testMethod void testGetUserGeoLocation(){
UserLocation userLocation = new UserLocation();
List<Double> userGeoLocation = userLocation.getUserGeoLocation('');

System.assertEquals(22.5667, userGeoLocation.get(0));
System.assertEquals(88.3667, userGeoLocation.get(1));

static testMethod void testGetUserAddress(){
UserLocation userLocation = new UserLocation();
Address userAddress = userLocation.getUserAddress('');

System.assertEquals('West Bengal', userAddress.State);
System.assertEquals('Kolkata', userAddress.City);
System.assertEquals('12345', userAddress.PostalCode);
System.assertEquals('India', userAddress.Country);
You will notice that the test method created above is using another new feature introduced in Spring ’15 i.e. @testSetup. I have written a post on that. Please check Spring ’15 – New Feature Added – @testSetup
This is really a great feature introduced. You as a developer now have huge power to do many things for example – calculating distance between two geolocations (I will write a post on this very soon).
You should read this great resource before start working with Compound fields. 
You can try this new feature in your own Spring ’15 Pre-release Org!
