There are two ways to create a Thread in Java: using the Thread class and using the Runnable interface. You must create a Thread instance when using the Runnable interface. Therefore, both the Thread class and Runnable interface must be used to create an instance of the Th

I have published a blog about multithreading development in iOS, which introduces NSThread, Operation queue, and GCD. Today, we will give a comprehensive summary of how GCD is used. The history and benefits of GCD are not described too much here. This blog will summarize GCD through a ser

Preface
A thread is a scarce resource. If it is created without limit, it will not only consume system resources, but also reduce system stability. It is reasonable to use the thread pool to uniformly allocate, optimi
[Java concurrent programming] 7. Thread Pool and java concurrent Thread Pool1.Why use Thread Pool
Many server applications, such as Web servers, database servers, file servers, or email servers, are designed to process a large number of short tasks from some remote sources. Requests arrive at the server in a certain way, which may be through the network protocol

In several cases:1. Whether the Synchronized keyword was added before other methods, if not added, it can.2. If wait is called internally by this method, you can enter another synchronized method.3. If all other methods add the Synchronized keyword and no wait is called internally, you cannot.4. If the other method is static, it uses a synchronous lock that is the byte code of the current class and cannot be synchronized with a non-static method because the non-static method uses this.When a
Problem
When we inherit the canvas class in J2ME, we will realize the runnable interface and realize the effect of multithreading. Personally think that actually this thread is just a timer function, can be used a timer or a inner class to achieve this function, There is not much discussion about this here.
Our run () function is generally to implement this function, timed to handle game logic gamelogic () and redraw the screen paint (). Note that th

Next we will create a Thread. When using the Thread class to create a Thread, we only need to provide the Thread entry. (The thread
The System.Threading namespace of the. NET Base Class Library provides a large number of classes and interfaces to support multithreading. There are many classes in this namespace. The System.Threading.Thread class is the most common class that creates and controls threads, sets their precedence, and obtains their state. He has a lot of ways, here we will introduce the more common and important methods to do the introduction:
Thread.Start (): Start the execution of the

Through synchronization, one thread can safely change values that another thread will read. How does the second thread know that the values have changed? What if the second thread is waiting for the values to change by rereading the values

Synchronized keyword
Synchronized, we call the lock, mainly used to lock the method, code block. When a method or block of code uses synchronized, at most one thread at the same time executes the code. When more than one thread accesses the lock method/code block of the same object, only one thread is executing at the same time, and the remaining threads must wa

Creating a New thread and starting it will incur a high overhead, because the running thread requires more resources than calling the object method. In many cases, threads are used to execute a type of task, which has a large number of tasks and the time distribution is uneven. If a
