1. Getter and Setter Methods • Setter methods • public methods that set the value of instance variables to a value specified by the call to the argument • Setter methods do not violate the idea of private data • you only change the variables you want • Returns void (i.e. nothing) • Getter methods • public method that displays value of private variables • Again, does not violate idea of private data • You only display values you want to display • Also called “accessor” or “query” methods • Other objects can treat the object as a black box

2. class carSetter { private String licensePlate; private int speed; void setlicensePlate(String plate) //setter method { licensePlate = plate; } void setspeed(intispeed) //setter method { speed=ispeed; } }//end class

3. class carSetter { private String licensePlate; private int speed; void setlicensePlate(String plate) //setter method { licensePlate = plate; } void setspeed(int ispeed) //setter method { speed=ispeed; } String getlicensePlate() //getter method { return licensePlate; } int getspeed() //getter method { return speed; } }//end class

4. class getter_Example { public static void main(String args[]) { carSetter a = new carSetter(); a.setlicensePlate("02 C 14"); a.setspeed(10); System.out.println(a.getlicensePlate() + " is moving at " + a.getspeed() + " mph."); }//main }//
