I think UDAY is right and he gave the right answer.
We actually couldn't instantiate the interface but we could
instantiate object from class implements this interface and
override all of its methods due to interfaces could only
have abstract methods, but also we can use anonymous inner
class to do that and must override all the abstract method
within creating the object. for ex:

interface Test {
void printA();
void printB();
}

class Inter implements Test {
@Override
void printA() {System.out.println("A from implement");}
void printB() {System.out.println("B from implement");}
}

public class A {
public static void main (String arg[]) {
Test t = new Test() {
void printA() { System.out.println("A form inner"); }
void printB() { System.out.println("B from inner"); }
};
Inter i = new Inter();
t.printA();
i.printA();
t.printB();
i.printB();
}
}
