AtomicIntegerArray

java.util.concurrent.atomic

Java 5.0

serializable

This class holds an array of int values. It provides threadsafe access to the array elements, treating each as if it was a volatile field, and defines atomic operations on them. The methods of this class are like those of AtomicInteger , except that each has an additional parameter that specifies the array index. Create an AtomicIntegerArray by specifying the desired array length or an actual int[ ] from which initial values can be copied .
