Randomizing String in ArrayList

Question

I need to be able to add words to my Hangman game so my previous arrays was created like this:

Random random = new Random();
String[] word = {"iran","japan","canada","america","malaysia"};
randomword = word[random.nextInt(word.length)];

The problem is that this array is fixed size, so I tried using ArrayList:

ArrayList<String> word = new ArrayList<String>();
word.add("iran");
word.add("japan");
word.add("canada");
Random random = new Random();
randomword = word[random.nextInt(word.length)];

but it didn't work, the error is (array required, but arrayList found)

randomword = word[random.nextInt(word.length)]; there is no syntax in java that allows you to use index with ArrayList , use get() instead.

Elements is an ArrayList are retrieved using the get(index) method, and the size() method is used instead of length.

change

randomword = word[random.nextInt(word.length)];

to

randomword = word.get(random.nextInt(word.size()));
