Thread: 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

Have you solved your problem now?
