question on Anonymous class

[Niranjan Deshpande]

this is taken feom K&B chapter 8

class AnonymousExamWatch{
public static void main(String args[]){
Food f=new Food();
f.p.pop(); 
/*this should call the pop method of class Popcorn
 *and print out "Popcorn". But why do we get output "Anonymous Popcorn"
 *i expect "Popcorn" because when it comes to overriding(pop( ) of Popcorn is 
 *overidden in anonymous subclass), compiler looks on the LHS of the line 
 *
 *Popcorn p=new Popcorn()..... ! and must give output "Popcorn", by calling
 *pop ( ) of Popcorn class
 *
 *But we get "Anonymous Popcorn".This means compiler is using the RHS(which it
 *does only when mwthod is overloaded) of the line to call a method.
 *
 *Can anyone please explain ???
 *
 */

//f.p.sizzle(); //this is illegal Agreed
}
}
class  Popcorn{
public void pop(){
System.out.println("Popcorn");
}
}
 
class Food{
Popcorn p=new Popcorn(){
public void sizzle(){
System.out.println("Popcorn sizzles");
}
public void pop(){
System.out.println("Anonymous Popcorn");
}
};
p.pop();    //line x
p.sizzle(); //line y
 
/*why doesnt these work  ???
 *
 *What code should i write @ lines x and y,
 *so that these to lines print "Popcorn sizzles"
 *and Anonymous Popcorn" ???
*/

}

Hi Niranjan,


p.pop(); //line x
p.sizzle(); //line y

These two lines are not in any method...
