AtomicLongArray getAndSet() method in Java with Examples
The Java.util.concurrent.atomic.AtomicLongArray.getAndSet() is an inbuilt method in Java that atomically sets a given value at any given position of the AtomicLongArray. The method takes the index value of the AtomicLongArray and the value to set as the parameters. It returns the value at the given index before setting the new value at that index. The function getAndSet() is similar to the set() function but the former returns value while the latter does not return any value.

Parameters: The function accepts two parameters:
Return value: The function returns the value at the given index before the update which is in long.
Below programs illustrate the above method:
The array : [11, 12, 13, 14, 15] Value at index 0 before the update is 11 The array after update : [100, 12, 13, 14, 15]
The array : [11, 12, 13, 14, 15] Value at index 3 before the update is 14 The array after update : [11, 12, 13, 10, 15]
