The java.util.concurrent.atomic.AtomicBoolean.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(boolean 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 function: Program 1:
// Java program that demonstrates
// the set() function
  
import java.util.concurrent.atomic.AtomicBoolean;
  
public class GFG {
    public static void main(String args[])
    {
  
        // Initially value as false
        AtomicBoolean val
            = new AtomicBoolean(false);
  
        System.out.println("Previous value: "
                           + val);
  
        val.set(true);
  
        // Prints the updated value
        System.out.println("Current value: "
                           + val);
    }
}

                    
Output:
Previous value: false
Current value: true
Program 2:
// Java program that demonstrates
// the set() function
  
import java.util.concurrent.atomic.AtomicBoolean;
  
public class GFG {
    public static void main(String args[])
    {
  
        // Initially value as true
        AtomicBoolean val
            = new AtomicBoolean(true);
  
        System.out.println("Previous value: "
                           + val);
  
        val.set(false);
  
        // Prints the updated value
        System.out.println("Current value: "
                           + val);
    }
}

                    
Output:
Previous value: true
Current value: false
