nested Interfaces

[Javasubbu]

I am practicing nested interfaces..I am missing out somewhere in the code. Can some one help..Below are the codes...

public class Aint {
	public interface notIf{
	boolean	ifNotPos(int i);
}
}

and

class Bint implements Aint.notIf{
	public boolean notIfPos(int i){
		return i < 0 ? false : true;
}
}

and the main program is

class Cint{
	public static void main(String args[]){
	Aint.notIf a1 = new Bint();
	System.out.println("The value is " + a1.ifNotPos(10));
	System.out.println("The value is " + a1.ifNotPos(-12));	
}
}

When I compile the error that I get is,

C:\Subbu\Java>javac Cint.java
.\Bint.java:1: error: Bint is not abstract and does not override abstract method
 ifNotPos(int) in notIf
class Bint implements Aint.notIf{
^
1 error

Can someone help...?

Check the method names.
