As I understand your question     From Java List class you have to methods add E e  and get int position    add E e    Appends the specified element to the end of this list  optional operation    get int index    Returns the element at the specified position in this list   Example   List lt String gt  myString   new ArrayList lt String gt         How you add your data in string list myString add  Test 1    myString add  Test 2    myString add  Test 3    myString add  Test 4        retrieving data from string list array in for loop for  int i 0 i  lt  myString size   i        Log i  Value of element   i myString get i        But efficient way to iterate thru loop  for  String value   myString      Log i  Value of element   value
