This article mainly introduces how to use AtomicIntegerArray, AtomicLongArray, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

Describes the use of atomic classes in the concurrency toolkit.

As in the previous article, the use of these classes is almost the same, so we use the AtomicIntegerArray class to demonstrate the use of the atomic class, because we have already experimented in the previous article, the classes under this package are indeed atomic, that is, thread-safe, so the focus of the following example is on the use of demonstration methods, rather than writing multithreaded programs.

The addAndGet () method in the AtomicIntegerArray class is basically the same as the addAndGet () method in the AtomicInteger class, except that there is an extra index parameter of the array, which is operated by manipulating the index value of the array object. Because the initialization array is 1, the index we changed is 1, so it updates the value because it is the second element in the array, 2 (the array index starts at 0), and because the function of the addAndGet () method is to perform the addition of parameters, the output value is 4.

Let's take a look at the compareAndSet () method.

The use of the compareAndSet () method is the same as above, still passing an index parameter, because the index we passed is 1, so update the second element in the array, that is, 2, because 2 and compareAndSet () method we expect the value of 2 is the same, so return true and set the value of the second parameter in the array to 3.

Thank you for reading this article carefully. I hope the article "how to use AtomicIntegerArray and AtomicLongArray" shared by the editor will be helpful to everyone. At the same time, I also hope you will support us and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
