    When you’re dealing with generic sObjects, you sometimes need to cast your sObject variable to a specific sObject type. One of the benefits of doing so is to be able to access fields using dot notation, which is not available on the generic sObject. Since sObject is a parent type for all specific sObject types, you can cast a generic sObject to a specific sObject.

    eg.

    Account acct = (Account)myGenericSObject;
    String name = acct.Name;
    String phone = acct.Phone;

    Hi,

    Example - 

    public static void dynamicUpsert(List<SObject> records)
    {
    Schema.SObjectType sObjectType = records.getSObjectType();
    if (sObjectType != null)
    {
    String listType = 'List<' + sObjectType + '>';
    List<SObject> castRecords = (List<SObject>)Type.forName(listType).newInstance();
    castRecords.addAll(records);
    upsert castRecords;
    }
    }

    Hope this helps.
