How to print an Array List on multiple lines?

Question

I\'m doing the MOOC java course, and I\'m stuck on exercise 76. Whenever I submit the answer it tells me to print each meal to a seperate line. How would I go about doing this?<

Answer 1

 import java.util.ArrayList;

public class Menu {

   private ArrayList<String> meals;

public Menu() {
    this.meals = new ArrayList<String>();
}

 public void addMeal(String meal) {
     if (!meals.contains(meal)) {
     meals.add(meal);      
 }
}
  public void printMeals() {
   if (meals.isEmpty()){
     System.out.println("No Meal Object Found !");
      return;
    }
for(String meal : meals) {
    System.out.println(meal);
    }
   }
  public void clearMenu(){
      meals.removeAll(meals);
  }
}

Answer 2

Just iterate over the list and print each item seperately:

  public void printMeals() {
    for(String meal : meals) {
        System.out.println(meal);
    }
  }

Answer 3

In Java 8

public void printMeals() {
    this.meals.stream().forEach(System.out::println);
}
