Alright here's my problem:

package questions.c1;
interface RiceCereal {
public void snap();
public void crackle();
public void pop();
}
public abstract class Krispies implements RiceCereal {
public void snap() {
System.out.println( "Snap!" );
}
public void crackle() {
System.out.println( "Crackle!" );
}
public static void main( String[] args) {
Krispies k = new Krispies();
k.snap();
}
}

The problem I get from compiling this code is that:
"Krispies is abstract and it cannot be instantiated" showing me the code "new Krispies" as the culprit. I am relatively new to Java and I was debugging a problem, now I am stuck with this, it debugged my whole brain. Searched through the net, and could not understand the solution from sun.java.com. My sajha friends, I need help.

How about changing:
public abstract class Krispies implements RiceCereal

to

public class Krispies implements RiceCereal

Abstract classes aren't supposed to be instatiated, hence your problem.
Couple of options: like mallazi said, don't declare your class to be abstract.
Or, make another class and extend the abstract class.

I ommitted the abstract, the error was that Krispies should be declared abstract. I declared abstract and it says cannot be instantiated. So I am guessing I will have to override or follow up with a sub-class to extend it. Question is how can it be done? Any idea as to how to make an extension?

Remove the main method from Krispies.
Create another class extending Krispies as:
public class XXX extends Krispies{
}
and plug the main method here and do whatever you need.
