Java ArrayList Index

Using an Array:

String[] fruits = new String[3]; // make a 3 element array
fruits[0]="apple";
fruits[1]="banana";
fruits[2]="orange";
System.out.println(fruits[1]); // output the second element

Using a List

ArrayList<String> fruits = new ArrayList<String>();
fruits.add("apple");
fruits.add("banana");
fruits.add("orange");
System.out.println(fruits.get(1));

List<String> aList = new ArrayList<String>();
aList.add("apple");   
aList.add("banana");   
aList.add("orange");   
String result = alist.get(1);  //this will retrieve banana

Note: Index starts from 0 i.e. Zero

You have ArrayList all wrong,

• You can't have an integer array and assign a string value.
• You cannot do a add() method in an array

Rather do this:

List<String> alist = new ArrayList<String>();
alist.add("apple");
alist.add("banana");
alist.add("orange");

String value = alist.get(1); //returns the 2nd item from list, in this case "banana"

Indexing is counted from 0 to N-1 where N is size() of list.
