Iterator pattern analysis, structure diagram and basic code, pattern structure Definition: provides a method to access each element of an aggregate object sequentially without exposing the internal representation of the object.Applicable: When you

Iterator and AVAIterator in AVA Iterator pattern (Iterator pattern) I. Introduction iteration is a perfect concept for Java beginners. We often use the iterative interface provided by JDK to traverse java collections: Iterator it = list. iterator ();

Iterator pattern: provides a method to access each element of an aggregate object sequentially without exposing the internal representation of the object. The iterator mode can be used to traverse a collection. Java also provides a tool class: Java.

Create a pattern1. Factory method Mode (Factory methods) The operation of creating objects in the program is processed separately, creating a factory interface for the product and transferring the actual work to the detailed subclass. The

Execution: for (iterator it = o.getsons (). iterator (); It.hasnext ();) { R = (Knowledgenode) it.next (); It.remove ();  If replaced by O.getsons (). Remove (R); Will throw out the abnormal concurrentmodificationexception. There is an exception,
