The set() 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 semantics of reading as if the variable was declared volatile type of variable.
Syntax:
public final void set(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 set() method:
Program 1:
// Java program to demonstrate// AtomicReferenceArray.set() method  import java.util.concurrent.atomic.*;  public class GFG {      public static void main(String[] args)    {          // create an atomic reference object.        AtomicReferenceArray<Integer> ref            = new AtomicReferenceArray<Integer>(5);          // set some value and print        ref.set(0, 2345);        ref.set(1, 543);        ref.set(2, 322);          System.out.println("Value of index 0 = "                           + ref.get(0));        System.out.println("Value of index 1 = "                           + ref.get(1));        System.out.println("Value of index 2 = "                           + ref.get(2));    }} |
Output:
Value of index 0 = 2345 Value of index 1 = 543 Value of index 2 = 322
Program 2:
// Java program to demonstrate// AtomicReferenceArray.set() method  import java.util.concurrent.atomic.*;  public class GFG {      public static void main(String[] args)    {          // create an atomic reference object.c        AtomicReferenceArray<String> ref            = new AtomicReferenceArray<String>(5);          // set some value        ref.set(0, "C");        ref.set(1, "PYTHON");        ref.set(2, "TS");        ref.set(3, "C++");        ref.set(4, "C");          // print        for (int i = 0; i < 5; i++) {            System.out.println(ref.get(i));        }    }} |
Output:
C PYTHON TS C++ C
