import java.util.Arrays;

public class BagTraceExample {

   public static void main(String[] args) {
      BagInterface<String> animalBag = newArrayBag();
      
          
      System.out.println(animalBag.isEmpty());
       animalBag.add(“alligator”);
       animalBag.add(“bear”);
       animalBag.add(“bear”);
       animalBag.add(“cat”);
       animalBag.add(“dog”);
       animalBag.add(“elephant”);
      System.out.println(animalBag.isEmpty());
       animalBag.add(“cat”);
       animalBag.add(“cat”);
      System.out.println(animalBag.getCurrentSize());
      System.out.println(animalBag.remove(“bear”));
      System.out.println(animalBag.getCurrentSize());
      System.out.println(animalBag.remove(“cat”));
      System.out.println(animalBag.remove(“cat”));
       animalBag.add(“cat”);
      System.out.println(animalBag.remove(“gorilla”));
      System.out.println(animalBag.getCurrentSize());
      System.out.println(animalBag.getFrequencyOf(“cat”));
      System.out.println(animalBag.contains(“gorilla”));
      System.out.println(animalBag.getFrequencyOf(“gorilla”));
       animalBag.clear();
      System.out.println(animalBag.getCurrentSize());
      System.out.println(animalBag.remove());
