Question

Is it possible to create in Java an array indexed by letter characters (‘a’ to ‘z’) rather than by integers?

With such an array “a”, I would like to useit in this way, for example

print (a['a']);

Answer 1

Use a Map instead.

Map<Character, Object> myMap = new HashMap<Character, Object>();
myMap.put('a', something);

print(myMap.get('a'));

On the other hand, as others already suggested, you can use a char as index (but you would leave all array elements 0...'a'-1 empty):

String[] a = new String['z' + 1];
a['a'] = "Hello World";
System.out.println(a['a']);
