As a Java programmer, the most painful thing is to choose a range too wide, can read too many books, often easily confused. I'd like to pick out some of the technical books I've read and recommend them to you in the order of study, especially to the Java programmers who want to keep improving their skills. First, Java programming into categoriesfor programmers w

operations of lock, unlock, read, load, assign, use, store, and write are atomic, but for 64-bit data types long and double, A loose rule is defined in the model that allows the virtual machine to divide the read and write operations of 64-bit data that are not volatile-modified into two 32-bit operations. Thus, if there are multiple threads sharing a long or double type of variable that is not declared volatile, and both are read and modified, some threads may read a value that is neither the

aborts the program, all threads abort its execution. When the run () method of the Thread object is invoked, the thread is not created, nor is the thread created when the class run () method that implements the Runnable interface is invoked. The thread is created only if the start () method of the thread object is invoked. Endless As mentioned at the beginning of this section, there is another way to create a thread: Inherit the thread class, override the Run () method, so that you can creat

Note that in any thread pool, existing threads are automatically reused whenever possible. Although this book will be used CachedThreadPool , it should also be considered in the code that generates the thread FiexedThreadPool .

The safest way to add a new atomic operation is to modify the original class to support the desired operation. However, you may not have access to the source code or the freedom to modify it, so it is usually impossible. Even if you can modify the original class, you also need to understand its implementation of the synchronization strategy, in order to maintain the original design of the premise to improve its functionality. Adding a new method directly to a class means that all code that imple

First, the atomic natureAtomicity means that an operation is non-interruptible. Even when multiple threads are executing together, an operation will not be disturbed by other threads once it is started.i++是原子操作吗？不是，包含3个操作：读i,i=i+1,写i32位的机子上读取64位的long型也不是原子操作Second, the order of 2.1 examplesDuring concurrency, the execution of the program may occur in a disorderly sequence2.2 StepsThe execution of an instruction can be divided into a number of steps:
