This exercise adds methods to the class meals to add and remove meals from the array.
My Code
import java.util.ArrayList;
public class Menu {
private ArrayList<String> meals;
public Menu() {
this.meals = new ArrayList<String>();
}
// add the methods here
public void addMeal(String meal) {
if (!this.meals.contains(meal)){
this.meals.add(meal);
}
}
public void printMeals(){
for (String m : meals) {
System.out.println(m);
}
}
public void clearMenu(){
meals.removeAll(meals);
}
}Model Code
import java.util.ArrayList;
public class Menu {
private ArrayList<String> meals;
public Menu() {
this.meals = new ArrayList<String>();
}
// add the methods here
public void addMeal(String meal) {
if (!this.meals.contains(meal)) {
this.meals.add(meal);
}
}
public void printMeals() {
for (String meal: this.meals) {
System.out.println(meal);
}
}
public void clearMenu() {
this.meals.clear();
}
}Comments
The major difference is that the model code uses this.meals.clear whereas I used meals.removeAll(meals) which was a mistake as I forgot the this..
