AtomicReferenceArray setRelease() method in Java with Examples

The setRelease() method of a AtomicReferenceArray class is used to set the value of the element at index i to newValue. Both index i and newValue are passed as parameters to the method. This method set the value with memory effects as specified by VarHandle.setRelease(java.lang.Object…). This method has memory ordering effects compatible with memory_order_release ordering.

Syntax:

public final void setRelease(int i, E newValue)

Parameters: This method accepts:

  • i which is an index of AtomicReferenceArray to perform the operation,
  • newValue which is the new value to set.

Return value: This method returns nothing.

Below programs illustrate the setRelease() method:

            + ref.get(1));
        System.out.println(
            "Value of index 2 = "
            + ref.get(2));
