Give an example for Using Getter Methods ?
class CarTest6 {
public static void main(String args[]) {
Car c = new Car();
c.setLicensePlate("New York A45 636");
c.setMaximumSpeed(123.45);
System.out.println(c.getLicensePlate() + " is moving at "
+ c.getSpeed() + " kilometers per hour.");
for (int i = 0; i < 15; i++) {
c.accelerate(10.0);
System.out.println(c.getLicensePlate() + " is moving at "
+ c.getSpeed() + " kilometers per hour.");
}
}
}
There's no longer any direct access to fields!
Here's the output:
