anonymous inner class

[pooja jain]

It is mention in Kathy & Bert book on 467 page . you can even have class within an argument of method that are anonymous inner class . but my doubt is they are not in method argument .

[Edwin Dalorzo]

What do you mean? Somewhat like this satisfies your statement:

class Base
{
  public void sayHello()
  {
    System.out.println("Hello World!!!");
  }
}
 
public class Answer1 
{
  public void greetSomebody(Base aBase)
  {
    aBase.sayHello();
  }
  
  
  public static void main(String args[])
  {
    Answer1 aAnswer = new Answer1();
    
    aAnswer.greetSomebody(new Base(){ //Anonymous implementation
      public void sayHello() //Method overrinding
      {
        System.out.println("Hello Everybody");
      }
    });
  }
}

new Base() { int i = 8 ; } ;

Pooja , You can consider this line like , this line is giving an reference of an anonymous class & that anonymous calss is a sub class of this Base class & implementation of that anonymous class is b/w the curly braces ...

So now you can have this statement any place where ever reference is required , in method argument, at the time of assigning to another reference ...

I hope it is right & clear to you ...
