You just can't assign a different object to a final variable. So the keys and values in your example are not constant, because you can change the HashMap as you like... My solution would be to create a Proxy object for HashMap or whatever you use and make it read-only... And why are you using ArrayList if you dont want to add items to the list? A simple array would do (new String[]{ "value1", "value2" ...}) Making an object final doesn’t mean you can’t modify it. You just can’t assign a different object to a final variable.
