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.
Syntax:
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
