The Java.util.concurrent.atomic.AtomicLong.set() is an inbuilt method in java that updates the previous value and sets it to a new value which is passed in the parameter.
Syntax:
public final void set(long newVal)
Parameters: The function accepts a single mandatory parameter newVal which is to be updated.
Return value: The function does not returns anything.
Below programs illustrate the above method:
Program 1:
// Java program that demonstrates// the set() function  import java.util.concurrent.atomic.AtomicLong;  public class GFG {    public static void main(String args[])    {          // Initially value as 0        AtomicLong val = new AtomicLong(0);          System.out.println("Previous value: "                           + val);          val.set(10);          // Prints the updated value        System.out.println("Current value: "                           + val);    }} |
Output:
Previous value: 0 Current value: 10
Program 2:
// Java program that demonstrates// the set() function  import java.util.concurrent.atomic.AtomicLong;  public class GFG {    public static void main(String args[])    {          // Initially value as 18        AtomicLong val = new AtomicLong(18);          System.out.println("Previous value: "                           + val);          val.set(200);          // Prints the updated value        System.out.println("Current value: "                           + val);    }} |
Output:
Previous value: 18 Current value: 200
