K&B Anonymous Inner Class.

[Minhaj Mehmood]

class Popcorn{
	public void pop(){
		System.out.println("popcorn");
	}
}

public class Food{
	static Popcorn p = new Popcorn(){
		public void pop(){
			System.out.println("anonymous popcorn");
		}
		public void sizzle(){
			System.out.println("anonymous sizzling popcorn");
		}
	};

	public static void main(String... args){
		p.pop();
		p.sizzle(); //compile time error here #how to "access sizzle newly created method" into anonymous inner class of Popcorn??
	}
}

You cannot access sizzle directly. There might be a way of doing that using reflection, but that's not in SCJP objectives so you don't need to worry...

[Minhaj Mehmood]

I see - thanks ankit. however, can you show me that reflection code to access sizzle?? if its convenient for you?

[Amrita Udupa]

Alternatively you could include the sizzle in your popcorn class and then call it in the main method

[Ankit Garg]

Here's a small code that I created to call a method on an anonymous inner class object which is not a part of the super class of the anonymous inner class.

class Try {

	public static void main(String[] args) {
		Try tr = new Try() {
			public void innerMethod() {
				System.out.println(">>>innerMethod<<<");
			}
		};
		try {
			Class klass = tr.getClass();
			Method method = klass.getMethod("innerMethod");
			method.invoke(tr);
		} catch(Exception e) {e.printStackTrace();}
	}
}

Remember I'm no reflection guru, I just looked at the docs and this article and made this program...

Hi.. what K&B stands for?..
sorry i don't know it abbreviation..

Thanks..

Hi Leonardo Carreira, the people around javaranch use k&B as short term of book Java 6 Study Guide by Katherine Sierra & Bert Bates.

It refers to SCJP Study Guide by Kathy Sierra and Bert Bates (K&B = Kathy & Bert)...

Mr.Ankit, it's absolutely fine if you are not guru, i just asked because i was not able to call method "sizzle()" through reflection my self.

Thanks

Well I said that because I had to make the method local class' method (innerMethod) public otherwise I was getting an exception. But I'm sure that non-public members of a class can be accessed using reflection, I just don't know why it didn't work (and I'm not interested in knowing as of now as I don't have any reason why I should learn reflection inside out )...
