AtomicLongArray set() method in Java with Examples

  • Last Updated : 08 Feb, 2019

The Java.util.concurrent.atomic.AtomicLongArray.set() is an inbuilt method in Java that sets a given value at any position of the AtomicLongArray. This method takes the index value of the AtomicLongArray 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.

public final void set(int i, long 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:




    // Java program that demonstrates
    // the set() function
      
    import java.util.concurrent.atomic.AtomicLongArray;
      
    public class GFG {
        public static void main(String args[])
        {
            // Initializing an array
            long a[] = { 1, 2, 3, 4, 5 };
      
            // Initializing an AtomicLongArray with array a
            AtomicLongArray arr = new AtomicLongArray(a);
      
            // Displaying the AtomicLongArray
            System.out.println("The array : " + arr);
      
            // Index where operation is performed
            int idx = 0;
      
            // The new value to update at idx
            long val = 10;
      
            // Updating the value at
            // idx applying set
            arr.set(idx, val);
      
            // Displaying the AtomicLongArray
            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:




    // Java program that demonstrates
    // the set() function
      
    import java.util.concurrent.atomic.AtomicLongArray;
      
    public class GFG {
        public static void main(String args[])
        {
            // Initializing an array
            long a[] = { 1, 2, 3, 4, 5 };
      
            // Initializing an AtomicLongArray with array a
            AtomicLongArray arr = new AtomicLongArray(a);
      
            // Displaying the AtomicLongArray
            System.out.println("The array : " + arr);
      
            // Index where operation is performed
            int idx = 3;
      
            // The new value to update at idx
            long val = 100;
      
            // Updating the value at
            // idx applying set
            arr.set(idx, val);
      
            // Displaying the AtomicLongArray
            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]
