Bill and Bob and Steve

Does Java have anything

Answer 1

Java 8 solution with java.util.StringJoiner

Java 8 has got a StringJoiner class. But you still need to write a bit of boilerplate, because it's Java.

StringJoiner sj = new StringJoiner(" and ", "" , "");
String[] names = {"Bill", "Bob", "Steve"};
for (String name : names) {
   sj.add(name);
}
System.out.println(sj);
