How to use sObject in Apex salesforce

Hi so today I was searching around the net to get some example to use sObjects of salesforce but I was not able to find some, so I decided to make one here with very easy approach.

• Declaring a sObject - sOject objAcc = new sObject (); // without type
                                   sOject objAcc = new Account (); // with type
• Getting field values - sOject objAcc = new Account ();
                                  Id oId = objAcc.Id;
                                  String nameAcc = objAcc.get('Name'); // "Name" is field's API name
• Setting field values - sOject objAcc = new Account ();
                                  objAcc.put('Name','TestName');

Hope this helps someone.
