If you want to use some of the predefined classes of the API in your class and extend the capabilities of the same class then you have to use import. With out importing a package/class you cannot extend/inherit the properties/methods of a class.

I hope i'am clear in a single line

Let me know your questions

Thank You

golikrishna...

Import and Extend are two different concepts...

IMPORT : with this keyword you specify the API's( that include classes) that are going to be used by the code ...a way of informing the compiler to look out for specific classes within the imported API's....

EXTEND : we usually use this keyword when we want to extend the functionality of an existing class...

Thanks,
Prashanth
