Iterator is a pattern that can separate the traversal behavior of sequence type data structures from the traversed objects. Next, I will share with you the Java Iterator through this article_Compiled by Power Node Java Academy, friends in need For reference, iterator is a pattern that can separate the traversal behavior of a sequence type data structure from the object being traversed, that is, we do not need to care about what the underlying structure of the sequence looks like. As long as you get this object, you can use an iterator to traverse the interior of this object. 1. IteratorJava provides a specialized iterator >Iterator. We can implement this interface for a certain sequence to provide standard Java iterator. The function after the Iterator interface is implemented is to "use" an iterator.

Java Enumeration_Compilation and Summary of Power Node
Introduction: The full name of enum is enumeration. It is a new feature introduced in JDK 5 and is stored in the java.lang package. This article introduces you to the knowledge related to Java enumeration. Friends who need it can refer to it 8. Introduction to Java language (power node arrangement) Introduction: Java is an object-oriented programming language that not only absorbs the various advantages of the C++ language, but also abandons the difficulties in C++ Understand the concepts of multiple inheritance, pointers, etc., so the Java language has two characteristics: powerful and simple to use. Here is an introduction to the Java language through this article. Friends who are interested can take a look. 9. Detailed explanation of Java basic data types graphic code (power node arrangement) Introduction: Java data types (types) can be divided into two major categories: primitive types and reference types. The following is the power node to organize the knowledge related to Java's basic data types. Friends who are interested can learn together 10. Java project development naming convention (power node arrangement) Introduction: The purpose of defining this specification is to make all documents in the project look like they were written by one person , increase readability and reduce losses caused by substitutions in the project team.

Java code will have performance differences when running on different platforms. 1) The implementation and optimization strategies of JVM are different, such as OracleJDK and OpenJDK. 2) The characteristics of the operating system, such as memory management and thread scheduling, will also affect performance. 3) Performance can be improved by selecting the appropriate JVM, adjusting JVM parameters and code optimization.

Reasons for writing platform-specific code in Java include access to specific operating system features, interacting with specific hardware, and optimizing performance. 1) Use JNA or JNI to access the Windows registry; 2) Interact with Linux-specific hardware drivers through JNI; 3) Use Metal to optimize gaming performance on macOS through JNI. Nevertheless, writing platform-specific code can affect the portability of the code, increase complexity, and potentially pose performance overhead and security risks.

Java will further enhance platform independence through cloud-native applications, multi-platform deployment and cross-language interoperability. 1) Cloud native applications will use GraalVM and Quarkus to increase startup speed. 2) Java will be extended to embedded devices, mobile devices and quantum computers. 3) Through GraalVM, Java will seamlessly integrate with languages such as Python and JavaScript to enhance cross-language interoperability.
