Is it possible to do the following?
private static ArrayList<integer<integer<String>>> myArrayList;
In other words, create an ArrayList with declared element syntax?
Example:
myArrayList[0][0] = "This is the string.";
If not, is it possible to do such with normal arrays?
It seems you are looking for multi-dimensional arrays in Java, declared as follows:
String [][] list = new String[10][10];
list[0][0] = "This is a string";
System.out.println(list[0][0]);
You can declare List of List in the following way: -
List<List<String>> listOfList = new ArrayList<List<String>>();
Initialize your List, and then to add a String to your list element: -
listOfList.add(new ArrayList<String>());
listOfList.get(0).add("my String");
You can do
List<List<String>> list = new ArrayList<List<String>>();
list.add(new ArrayList<String>());
list.get(0).add("This is the string");
What you would want to achieve in realtime?, Java defines set of APIs, which has its own usage and purpose. If you want to use multidimensional array, I would suggest to go for Object[][], though you should be able to declare
ArrayList list[][] = new ArrayList[5][7];
By doing so, you would be making you operation bit complex. And more over ArrayList is nothing but single dimensional Object array.
FYI
new ArrayList[5][7] will instantiate an array of arrays of raw ArrayLists, which isn't what the OP wants. You probably meant what Peter and Rohit demonstrate.
integershould beIntegerand also you cannot doInteger<String>. that's not allowed.
