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
