An interface is like a class in which none of the methods have been implemented—the method signatures are there, but the body of each method is empty. To use an interface, another class must implement it by providing a body for all of the methods contained in the interface.

Interfaces can provide a layer of abstraction to your code. They separate the specific implementation of a method from the declaration for that method. This way you can have different implementations of a method based on your specific application.

51.I have added an string 'updated' to all users in Account object through batch apex,now how to remove that 'updated'?

• Create record types for cases to display different page layouts for your customer support cases versus your billing cases.

apex:actionPoller

     A timer that sends an AJAX update request to the server according to a time interval that you specify. The update request can then result in a full or partial page update. You should avoid using this component with enhanced lists.

66.   What is Dynamic Apex?
Dynamic Apex allows to create more flexible applications by providing them with the ability to:

Access sObject and field describe information

      Describe information provides information about sObject and field properties. For example, the describe information for an sObject includes whether that type of sObject supports operations like create or undelete, the sObject's name and label, the sObject's fields and child objects, and so on. The describe information for a field includes whether the field has a default value, whether it is a calculated field, the type of the field, and so on.

Note that describe information provides information about objects in an organization, not individual records.

Write dynamic SOQL queries, dynamic SOSL queries and dynamic DML

      Dynamic SOQL and SOSL queries provide the ability to execute SOQL or SOSL as a string at runtime, while dynamic DML provides the ability to create a record dynamically and then insert it into the database using DML. Using dynamic SOQL, SOSL, and DML, an application can be tailored precisely to the organization as well as the user's permissions. This can be useful for applications that are installed fromForce.com AppExchange.
