iterator methods

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()){

1.an iterator (iterator) is a data type that examines the elements within a container and iterates through the elements. (1) Each container type defines its own iterator type, such as vector:Vector::iterator ITER; This statement defines a variable

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 ();

Design Mode-iterator ModeOverview In software development, we often need to use aggregate objects to store a series of data. Aggregation objects have two responsibilities: one is to store data, and the other is to traverse data. From the perspective

Definition:Provides a method to access each element in a container object without exposing the internal details of the object. Type:Behavior mode Class diagram: If you want to ask the most common mode in Java, the answer is not the singleton mode,

1. an iterator (iterator) is a data type that examines the elements within a container and iterates through the elements. (1) Each container type defines its own iterator type, such as vector:Vector::iterator ITER; This statement defines a variable

PS One sentence: Eventually choose Csdn to organize the publication of the knowledge points of these years, the article parallel migration to CSDN. Because CSDN also support markdown grammar, Ah!"Craftsman Joshui Http://blog.csdn.net/yanbober" read

Design mode (14) Iterator mode iterator (object behavior type)1. Overview Object-oriented programming in a class encapsulates the application logic. Class is an instantiated object, each individual object has a specific identity and state.

Introduction: the software design model is a new method for expressing, recording, and reusing the software design structure and design experience. It identifies, abstracts, and names the key features of repeated design structures, it makes it

1. Overview Class. Class is an instantiated object. Each individual object has a specific identity and status. A separate object is a useful way to organize code, but you usually process a group of objects or collections. The set is not
