问如何如何访问数组：Java？

EN

List<String> fixedLenghtList = Arrays.asList(elements);
ArrayList<List<String>> listOfString = new ArrayList<List<String>>(fixedLenghtList);

for (List<String> stringList : listOfString) {
    for (String e : stringList) {
        System.out.println(e);
    }
}

ArrayList<String> listOfString = new ArrayList<String>(Arrays.asList(elements));

// inputs objects
    String[] elements = {"elem 1","elem 2","elem 3"};
    List<String> fixedLenghtList = Arrays.asList(elements);

    String[] otherElements = {"elem 4", "elem 5", "elem 6", "elem 7", "elem 8"};
    List<String> otherFixedLenghtList = Arrays.asList(otherElements);

    // a new instance of arraylist of empty list of strings
    ArrayList<List<String>> listOfString = new ArrayList<List<String>>();

    // add two list of string -> fixedLengthList, otherFixed...
    listOfString.add(fixedLenghtList);
    listOfString.add(otherFixedLenghtList);

    // java 8 foreach, now it's easy and similar to C# 
    listOfString.forEach(itemListOfString -> itemListOfString.forEach(System.out::println));    

    // outpout on stdout :

   //       elem 1
   //       elem 2
   //       elem 3
   //       elem 4
   //       elem 5
   //       elem 6
   //       elem 7
   //       elem 8
