The
Java.util.concurrent.atomic.AtomicIntegerArray.getAndSet() is an inbuilt method in Java that atomically sets a given value at any given position of the AtomicIntegerArray. The method takes the index value of the AtomicIntegerArray 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.
Syntax:
public final int getAndSet(int i, int newValue)
Parameters: The function accepts two parameters:
- i – The index where update is to be made.
- newValue – The value to set at index i
Return value: The function returns the value at the given index before the update which is in
Integer.
Below programs illustrate the above method:
Program 1:
Output:
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]
