AtomicLong lazySet() method in Java with examples

The Java.util.concurrent.atomic.AtomicLong.lazySet() 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 lazySet(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 lazySet() 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.lazySet(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 lazySet() 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.lazySet(200);
  
        // Prints the updated value
        System.out.println("Current value: "
                           + val);
    }
}


Output:

Previous value: 18
Current value: 200
