How to split Address in Salesforce?

Hi Bhanu,
You can use a specific identifier to split the custom address field into address components and store in proper address fields.You should determine the identifier in your custom address field. Usually the identifier will be Comma(,).

Custom Address Field value = 45, CLARENCE ST, SYDNEY, NSW 2000

In your apex method,

List<String> lstofAddress = object.customField__c.split(',');
object.AddressField1 = lstStringAddress[0];
object.AddressField2 = lstStringAddress[1];
object.AddressField3 = lstStringAddress[2];
object.AddressField4 = lstStringAddress[3];
object.AddressField5 = lstStringAddress[4];

Thanks.
