introduction About Runnable and Callable interfaces, you may have learned a concept when you first learned Java multithreading programming: there are three ways to create multithreading in Java: Inheriting Thread class, implementing Runnable interface and implementing Callable interface. But in fact, there is only one way to create multithread ...

😎 preface Today - 1024, the national programmer's Carnival, the blogger once set up a vote to see that everyone is more interested in the blogger's column. According to the results, it is found that JAVA is the most popular, so the author presents this long article as agreed to take a good look at the threaded world in JAVA. The author ...

introduction In fact, when we explained the principle of synchronized keyword in Java Concurrent Programming in our last article, we talked about the concept of CAS many times, so what is it? In fact, in order to solve the thread safety problems caused by multi-threaded parallel execution, we often use the locking mechanism to change multi-thr ...

Learn computer network programming 1, Ideas and learning methods    this article learned from: C language technology network (www.freecplus.net), and gave some understanding and reproduction. If there is infringement, it will be deleted.    now I have learned the basic knowledge of C + + and algorithms, and completed the b ...

appendix In 2014, I have sorted out the relevant java Concurrent Programming interview questions, here as an appendix to reorganize 1.There are three threads: T1, T2 and T3. How can I ensure that T2 executes after T1 and T3 executes after T2? Use join method The function of the join method is to make asynchronous threads execute synchronous ...

11. Mutex initiate static pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER;      The memory unit is not released until the process is completed dynamic initialization pthread_mutex_t mutex; // Define mutex objects pthread_ mutex_ init(&mutex, NULL); // Allocate kernel resources ... pthread_ mutex_ destroy(&mutex); // F ...

deadlock Multiple threads occupy some shared resources and wait for the resources occupied by other threads to run. As a result, two or more threads are waiting for each other to release resources and stop execution. When a synchronization block has "locks of more than two objects" at the same time, the problem of "deadlock&quot ...

What is a process? There are many separate programs running in the computer. Each program has an independent process, and the processes exist independently of each other. For example, idea,360, qq and so on in the figure below. Note: a process can contain multiple threads What is a thread? Processes that want to perform tasks need to rely on ...

preface Starting from this section, we will formally enter the study of concurrent programming design pattern. First, we will talk about the observer design pattern. We will start with the java design pattern, and then transition to the observer pattern of concurrent programming 1, What is the observer design pattern? About what is t ...
