that a certain, expected (memory) state is true across different threads, while Atomics ensure that operation on variables are performed atomically. Take the following example of two threads in Java: Thread A: value = 1; done = true; Thread B:...

请注意,拥有一个可递增/可递减的东西的任务已经存在:AtomicInteger,如果这是您的实际意图,您应该使用它来代替它(但我假设您只是作为一个示例编写的)。注:java内存模型最好理解为一枚邪恶的硬币。邪恶的是,它会给你带来麻烦:让代码在 Multithreading using synchronized ...
The rules that determine how memory accesses are ordered and when they are guaranteed to be visible are known as thememory modelof the Java programming language. If all reads and writes to a variable occur only when a specific monitor is held, then each read of the variable is guaranteed b...

multithreadingdynamic slicingThis paper proposes an efficient slicing algorithm for prioritizing synchronized multithreaded programs. The algorithm would compute precise slices in multiple thread execution environments. The equal priority threads having the maximum priority would execute in a synchronized way ...
when a method is synchronized it can be accessed by only one thread at a time. Volatile modifier volatile modifier tells the compiler that the volatile variable can be changed unexpectedly by other parts of your program. Volatile variables are used in case of multithreading program....
