    Default ArrayList error

    Hi,

    I have this code from a site and I tried to run it but have an error.

    package myProject;
     
    import java.util.ArrayList;
     
    public class listArray2D {
     
    	public static void main(String[] args) {
     
    		ArrayList<ArrayList<String>> groceryList = new ArrayList();
     
    		ArrayList<String> bakeryList = new ArrayList();
    		bakeryList.add("pasta");
    		bakeryList.add("garlic bread");
    		bakeryList.add("donuts");
     
    		ArrayList<String> produceList = new ArrayList();
    		produceList.add("tomatoes");
    		produceList.add("zucchini");
    		produceList.add("peppers");
     
    		ArrayList<String> drinksList = new ArrayList();
    		drinksList.add("soda");
    		drinksList.add("coffee");
     
    		groceryList.add(bakeryList);
    		groceryList.add(produceList);
    		groceryList.add(drinksList);
     
    		System.out.println(groceryList);
     
    	}
     
    }
    the error is:
    Exception in thread "main" java.lang.Error: Unresolved compilation problems:
    ArrayList cannot be resolved to a type
