Can I create an object for Interface?

Question

Is it possible to create an object for an interface? If yes, how is it done? According to my view the following code says that we can:

Answer 1

Here's my understanding.

An interface

public Interface SomeInterface{
}

You can declare an Object for an interface.

SomeInterface anObject;

You cannot instantiate this object directly using this interface. However, let's say you have a class that implements this interface.

public class SomeClass implements SomeInterface {}

Then you can do this,

anObject = new someClass();

(This is conceptually of course (like pseudocode) actual code may vary depending on your classes and access modifiers etc.)

I'll update as to why exactly we are doing this/what the point is as soon as I find out.

Note: Some of this has been mentioned in above answers, just want the OP to know this whole thing too.
