Discussion Topic 1 — Access methods It is normal for a Java class to restrict access to its class and instance variables. For example, if class X wants to get the value of a variable in class Y, it would normally call a method (an accessor method) in class Y to do this. Although it is possible to read an instance variable in a different object directly, like this: int minutes = calendar.minutes; We would normally use an accessor method, like this: int minutes = calendar.get (Calendar.MINUTE); Working this way leads to a slight increase in the complexity of every class, as accessor methods need to be provided to control access to a number of variables. So why is this way of working so widespread? What advantages does it have? Contribution for Discussion Topic 1 ?Access methods
