Definitely no. We can create reference only. We can assign the implemented class's object to the interface reference.

yes sure.
her's an AWT example

Button closingButton = new Button("CLOSE");
closingButton.addActionListener(
new ActionListener(){
public void actionPerformed(ActionEvent ae){
System.exit(0);
}
}
);

Its an example of anonymous inner class.
actually its a trick, its not an object of ActionListener interface but an object of the class (implicitly) implementing ActionListener. But simply it looks as "new ActionListener()" thats y i said yes!!!

By the way, interfaces are implicitly abstract, they cannot be directly instantiated. Interfaces are special to java, as they provide so many features to java,

1) Polymorphism.

2) multiple inheritance (as a class can implement zero or more interfaces & an interface can extend zero or more interfaces)

3) Function callback.

4) Marker interface.(java.lang.Cloneable, java.io.Serializable, java.rmi.Remote these interfaces are marker interfaces)

...... and much more..

Yes we can create the objects of all those interfaces in java as shown by swapnilkumar.
Actually, its not creating an object of interface, but we can do it that way, its a nice trick.

Objects can only be created from new() function ....

try analysing the JVM HEAP , with JVM heap analyser tool , bet you won't find any object of an interface alteast
