join()

Combines an array of Strings into one String, each separated by the character(s) used for the separator parameter. To join arrays of ints or floats, it's necessary to first convert them to Strings using nf() or nfs().

• String[] animals = new String[3]; 
  animals[0] = "cat"; 
  animals[1] = "seal"; 
  animals[2] = "bear"; 
  String joinedAnimals = join(animals, " : "); 
  println(joinedAnimals);  // Prints "cat : seal : bear" 
  
  // Joining an array of ints requires first
  // converting to an array of Strings
  int[] numbers = new int[3]; 
  numbers[0] = 8; 
  numbers[1] = 67; 
  numbers[2] = 5; 
  String joinedNumbers = join(nf(numbers, 0), ", "); 
  println(joinedNumbers);  // Prints "8, 67, 5"
