AtomicLong set() method in Java with examples

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
