AtomicIntegerArray addAndGet() method in Java with Examples
The Java.util.concurrent.atomic.AtomicIntegerArray.addAndGet() is an inbuilt method in Java that atomically adds the given value to the element at an index of the AtomicIntegerArray. This method takes the index value and the value to be added as the parameters and returns the updated value at this index.
Syntax:
public int addAndGet(int i, int delta)
Parameters: The function accepts two parameters:
i – The index where value is to be added.
delta – The value to be added.
Return value: The function returns the updated value which is in Integer.
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[] = { 10 , 22 , 33 , 44 , 55 };
AtomicIntegerArray arr = new AtomicIntegerArray(a);
System.out.println( "The array : " + arr);
int idx = 0 ;
int x = 16 ;
arr.addAndGet(idx, x);
System.out.println( "The array after update : "
+ arr);
}
}
|
Output:
The array : [10, 22, 33, 44, 55]
The array after update : [26, 22, 33, 44, 55]
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 x = 16 ;
arr.addAndGet(idx, x);
System.out.println( "The array after update : "
+ arr);
}
}
|
Output:
The array : [1, 2, 3, 4, 5]
The array after update : [1, 2, 3, 20, 5]
