/*
CSE 142, Autumn 2007, Marty Stepp

This class models a Parent driving children to DisneyLand.
It is kind of a stupid example, but we're using it to illustrate the following:

- Sometimes I will ask you to write a method (e.g. areWeThereYet) without telling
  you what fields the object will need

- A useful trick is to count the number of calls of a given method, so that you can
  potentially produce a different response to each call
*/
public class Parent {
    // counts how many times the kids have asked us "are we there yet?"
    int timesAsked;
    
    // technically this constructor is not necessary
    public Parent() {
        timesAsked = 0;
    }
    
    // Simulates the parent's response to the annoying question, "Are we there yet?"
    // The Parent gets progressively more annoyed until it grounds the child.
    public String areWeThereYet() {
        timesAsked++;
        if (timesAsked <= 2) {
            return "Just a little farther.";
        } else if (timesAsked <= 4) {
            return "NO.";
        } else if (timesAsked == 5) {
            return "STOP ASKING ME THAT!";
        } else {
            return "You're grounded.";
        }
    }
