Explain the Member Access Separator ?
class Car {
String licensePlate; // e.g. "New York 543 A23" double speed; // in kilometers per hour double maxSpeed; // in kilometers per hour
}Once you've constructed a car, you need to do something along with it. To access the fields of the car you use the . separator. The Car class has three fields • licensePlate • speed • maxSpeed Thus if c is a Car object, c has three fields as well: • c.licensePlate • c.speed • c.maxSpeed You use these only like you'd use any other variables of the similar type. For example: Car c = new Car(); c.licensePlate = "New York A45 636"; c.speed = 70.0; c.maxSpeed = 123.45; System.out.println(c.licensePlate + " is moving at " + c.speed + "kilometers per hour.");The . separator selects a exact member of a Car object through name.
