Object and reference In the example

Here, aRef is not an object, it's a variable which contains a reference to an object. Objects don't have names, just types and locations in memory (and, of course,fields and methods). Read your statement as: Create a new SomeObject object in memory, initializing it with the data sent as arguments to a constructor, and when created, assign a reference to that object to the SomeObject variable aRef. aRef is a reference or object type variable which may reference a SomeObject object or an object of any subclass of SomeObject.

Using anonymous Inner class concept we can create an object for an interface…..

Here is a sample code

interface Sample {
public void method();
}

class Outer {
Sample s = new Sample() {
public void method() {
System.out.println("Inner class");
}
};
}

public class Example {
public static void main(String args[]) {
Outer o = new Outer();
o.s.method();
}
}

Output: Inner class
