Closure in Java 6

There is a way to encapsulate variable’s value into definition another method. Of course, it is far less flexible than “real” closure, like that one in JavaScript… but in my humble opinion it is still closure!
Keyword final and new inner class are required:

 
public static void main(String []  args) {

	final String SECRET = "HELLO CLOSURE";

	class InnerSecretClass{

		public String getSecret(){
			return SECRET;
		}
	}

	System.out.println(new InnerSecretClass().getSecret());

}
