This course is aimed at 0 basic students, or students who have been learning to program for a long time but have never done anything. Shang Teacher carefully designed the project development process, so that you in 60 minutes, from the installation of the Java development environment, using the Eclipse development environment, until the development of a billiard game. It makes you suddenly realize how inter
Java Collection series [3] ---- HashMap source code analysis, java ---- hashmap
We have analyzed the ArrayList and ArrayList sets. We know that ArrayList is implemented based on arrays, and ArrayList is implemented based on linked lists. They each have their own advantages a
Java concurrency series [6] ---- Semaphore source code analysis, java ---- semaphore
Semaphore is a common class in the JUC package. It is an application in the AQS sharing mode and allows multiple threads to operate on shared resources at the same time, in addition, it can
Java-linked list source code principle analysis, and build a queue through the consumer list, java-linked list
Here we will introduce the simplest linked list listing;
Let's take a look at the add () method:
public boolean add(E e) { linkLast(e); return true;

Interpretation of source code based on Annotation configuration Bean Definition

Comparison of String, StringBuffer and StringBuilder in Java and source code analysisIt is well known that string, StringBuffer, and StringBuilder are common strings in Java, and I will compare the three brothers in three ways.the data organization and its function realization of the first and third peopleWe love the s
Java Collection source code analysis (2) ArrayList, javaarraylistArrayList Overview
ArrayList is implemented based on arrays. It is a dynamic array with its capacity Automatically increasing. It is similar to dynamic memory application in C language and dynamic memory growth.
ArrayList is NOT thread-safe and can only b
Java Source Code Analysis: VectorAlthough, vector collection in our programming, use less, at least I use less, in general, I tend to use the list to store some of the same type of elements.In fact, the internal implementation of the vector and the internal implementation of the ArrayList are basically consistent, the
Java Collection framework 08 -- HashMap and source code analysis1. Introduction to HashMap
First, let's take a look at the inheritance relationship of HashMap.
