AtomicLongArray.getAndDecrement(int i) has the following syntax.
public final long getAndDecrement(int i)
In the following code shows how to use AtomicLongArray.getAndDecrement(int i) method.
/*w w w .ja v a 2 s . co m*/ import java.util.concurrent.atomic.AtomicLongArray; public class Main { public static void main(String[] argv) throws Exception { AtomicLongArray atomicLongArray = new AtomicLongArray(new long[]{1L,2L,3L,4L}); System.out.println(atomicLongArray.getAndDecrement(2)); System.out.println(atomicLongArray); } }
The code above generates the following result.
