Question

Is it possible to do something like this in Java for Android (this is a pseudo code)

IF (some_string.equals("john" OR "mary" OR "peter" OR "etc."){
   THEN do something
}

?

At the moment this is done via multiple String.equals() condition with || among them.

Possibilities:

• Use String.equals():

  if (some_string.equals("john") ||
      some_string.equals("mary") ||
      some_string.equals("peter"))
  {
  }
  

• Use a regular expression:

  if (some_string.matches("john|mary|peter"))
  {
  }
  

• Store a list of strings to be matched against in a Collection and search the collection:

  Set<String> names = new HashSet<String>();
  names.add("john");
  names.add("mary");
  names.add("peter");
  
  if (names.contains(some_string))
  {
  }
