AtomicIntegerArray set() method in Java with Examples
Last Updated :

The Java.util.concurrent.atomic.AtomicIntegerArray.set() is an inbuilt method in Java that sets a given value at any position of the AtomicIntegerArray. This method takes the index value of the AtomicIntegerArray as parameter and updates the value at that index. This method does not return any value. The function set() is similar to getAndSet() function but the former does not return any value while the latter returns the value at the given index before setting the new value at that index.
Syntax:
public final void set(int i, int newValue)
Parameters: The function takes two parameters:
- i – The index value where the update is to be made.
- newValue – The new value to update at the index.
Return Value: The function does not return any value.
Below programs illustrate the above method:
Program 1:
import java.util.concurrent.atomic.AtomicIntegerArray;
public class GFG {
public static void main(String args[])
{
int a[] = { 1 , 2 , 3 , 4 , 5 };
AtomicIntegerArray arr = new AtomicIntegerArray(a);
System.out.println( "The array : " + arr);
int idx = 0 ;
int val = 10 ;
arr.set(idx, val);
System.out.println( "The array after update : "
+ arr);
}
}
|
Output:
The array : [1, 2, 3, 4, 5]
The array after update : [10, 2, 3, 4, 5]
Program 2:
import java.util.concurrent.atomic.AtomicIntegerArray;
public class GFG {
public static void main(String args[])
{
int a[] = { 1 , 2 , 3 , 4 , 5 };
AtomicIntegerArray arr = new AtomicIntegerArray(a);
System.out.println( "The array : " + arr);
int idx = 3 ;
int val = 100 ;
arr.set(idx, val);
System.out.println( "The array after update : "
+ arr);
}
}

Output:
The array : [1, 2, 3, 4, 5]
The array after update : [1, 2, 3, 100, 5]
