How can I check if an element exists in a Set of items?

Question

In an if statement in Java how can I check whether an object exists in a set of items. E.g. In this scenario i need to validate that the fruit will be an apple, orange or banana.

if (fruitname in ["APPLE", "ORANGES", "GRAPES"]) {     //Do something } 

It's a very trivial thing but I couldn't figure out a short and concise way to accomplish this.

Answer 1

static final List<String> fruits = Arrays.asList("APPLE", "ORANGES", "GRAPES");  if (fruits.contains(fruitname)) 

If your list was much larger, a set would be more efficient.

static final Set<String> fruits = new HashSet<String>(        Arrays.asList("APPLE", "ORANGES", "GRAPES", /*many more*/));
