Inner Class

[Siva kandasamy]

Hi there,
I have couple of questions.
1. Why do I need interface "Contents.java" to compile "Parcel6.java"

 
//: c08:Contents.java
      public interface Contents {
        int value();
      } ///:~

  
//: c08   :-P	 arcel6.java
      // A method that returns an anonymous inner class.
      public class Parcel6 {
        public Contents cont() {
          return new Contents() {
            private int i = 11;
            public int value() { return i; }
          }; // Semicolon required in this case
        }
        public static void main(String[] args) {
          Parcel6 p = new Parcel6();
          Contents c = p.cont();
        }
      } ///:~

2. How the both definitions are same.

return new Contents() {
private int i = 11;
public int value() { return i; }
};

class MyContents implements Contents {
private int i = 11;
public int value() { return i; }
}
return new MyContents();
