Instead of defining public getters to expand access to private instance
variables and methods, you can expand access, without providing totally
public access, by marking the instance variables and methods with the
protected keyword, rather than with the public or
private keywords. Variables and methods so marked are said to be in
the protected part of the class definition, which, by convention, generally
is defined between the public and private parts of the class definition:
public class Attraction {
// Define zero-parameter constructor:
public Attraction () {minutes = 75;}
// Define one-parameter constructor:
public Attraction (int m) {minutes = m;}
// Define getter:
public int getMinutes () {return minutes;}
// Define setter:
public void setMinutes (int m) {minutes = m;}
// Define protected variable:
protected int minutes;
}
