Fields can (and often should) be initialized while they're declared, just like local variables.class Car {
String licensePlate = ""; // e.g. "New York 543 A23" double speed = 0.0; // in kilometers per hour double maxSpeed = 123.45; // in kilometers per hour
}The next program creates a new car and prints it: class CarTest2 {
public static void main(String[] args) { Car c = new Car(); System.out.println(c.licensePlate + " is moving at " + c.speed + "kilometers per hour."); } }For example, $ javac Car.java$ javac CarTest2.java$ java CarTest is moving at 0.0 kilometers per hour.
