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 ();

Java (article 30) ----- Iterator, java ----- iterator Iteration is no stranger to Java. We often use the iterative interfaces provided by JDK to iterate Java sets. Iterator iterator = list.iterator(); while(iterator.hasNext()){

vector Container Vectors are a collection of objects of the same type, each with a corresponding integer index value. As with string objects, the standard library is responsible for managing the associated memory of the storage element. We refer to

An Introduction to Iterators Overview An iterator is a data type that examines the elements inside a container and traverses the elements. An iterator (iterator) is an object that can be used to traverse some or all of the elements in a

The central idea of the STL is to separate the data container from the algorithm, design each other independently, and then bring them together with a stick agent. The binder is the iterator, the purpose of the iterator design is to easily obtain

I. Introduction In my previous blog post, I shared my understanding of the command mode. The command mode mainly abstracts the behavior into commands, making the behavior of the requester and the behavior of the recipient form a low coupling. In

First, IntroductionIn my previous blog post, I shared my understanding of the command pattern, which was mainly to abstract the behavior into commands, which resulted in low coupling between the requester's behavior and the recipient's behavior. In

One, iterator (Iterator) modeIterators are made for collection objects, which inevitably involve the addition and deletion of collection elements, and certainly support the operation of iterating over the collection elements, and we can put the
