How do i iterate through this arraylist ?

I'm relatively new to programming. I'm trying to teach myself Java, and I'm messing around with ArrayLists. How do I go about printing each of these strings individually? Right now, I have it where it prints each list, but I want to be able to work with each string individually. Like if I wanted to print out the length of each string using a for loop how would I do that? I tried doing the standard for loop, but I couldn't figure out what to put for the termination requirement. I tried i < 2 since test[3] is length 2, but that gave an out of bounds error since the other test lists only have one element.

public static void main(String[] args)

{

  int arrlen = 4;

  ArrayList[] test = new ArrayList[arrlen];

  for(int i=0; i<arrlen; i++)

  {

    test[i] = new ArrayList<String>();

  }

  test[0].add("zero");

  test[1].add("one");

  test[2].add("two");

  test[3].add("three");

  test[3].add("second three");

  for(ArrayList i : test)

  {

    System.out.println(i);

  }

}

Hey Andrew Lygin ,

For Solving Your Problem I have to use a simple get method for finding all elements of ArrayList inside for loop and by using length method  find length of elements of ArrayList .

ArrayList<String> test=new ArrayList<String>();

      test.add("one");

      test.add("two");

      test.add("three");

      test.add("four");

      for(int i=0;i<test.size();i++){

        System.out.println(test.get(i).length());

      }

      System.out.println(test);
