  • Last Updated : 05 Feb, 2019

The Java.util.concurrent.atomic.AtomicLongArray.get() is an inbuilt method in java that gets the current value at any position of the AtomicLongArray. This method takes the index value as the parameter and returns the value at this index.

public final long get(int i)

Parameters: The function accepts a single parameter i i.e the value of index to get.

Return value: The function returns the current value at index i.



Below programs illustrate the above method:

Program 1:




// Java program that demonstrates
// the get() 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 to get
        int idx = 2;
  
        // Using get() to retrieve value at idx
        long val = arr.get(idx);
  
        // Displaying the value at idx
        System.out.println("Value at index " + idx
                           + " is " + val);
    }
}
Output:
The array : [1, 2, 3, 4, 5]
Value at index 2 is 3

Program 2:




// Java program that demonstrates
// the get() function
  
import java.util.concurrent.atomic.AtomicLongArray;
  
public class GFG {
    public static void main(String args[])
    {
        // Initializing an array
        long a[] = { 12, 22, 23, 24, 25 };
  
        // Initializing an AtomicLongArray with array a
        AtomicLongArray arr = new AtomicLongArray(a);
  
        // Displaying the AtomicLongArray
        System.out.println("The array : " + arr);
  
        // Index to get
        int idx = 4;
  
        // Using get() to retrieve value at idx
        long val = arr.get(idx);
  
        // Displaying the value at idx
        System.out.println("Value at index " + idx
                           + " is " + val);
    }
}
Output:
The array : [12, 22, 23, 24, 25]
Value at index 4 is 25
