To display the current time (hour, minute, second, and nanoseconds), import the java.time.LocalTime class, and use its now() method:
Example
import java.time.LocalTime; // import the LocalTime class
public class Main {
  public static void main(String[] args) {
    LocalTime myObj = LocalTime.now();
    System.out.println(myObj);
  }
}
The output will be:
