AtomicLong set() method in Java with examples

0 1 1 minute read

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);
    }
}
