Java: convert List to a String

Question

JavaScript has Array.join()

js>[\"Bill\",\"Bob\",\"Steve\"].join(\" and \")
Bill and Bob and Steve

Does Java have anything

Answer 1

With a java 8 collector, this can be done with the following code:

Arrays.asList("Bill", "Bob", "Steve").stream()
.collect(Collectors.joining(" and "));

Also, the simplest solution in java 8:

String.join(" and ", "Bill", "Bob", "Steve");

or

String.join(" and ", Arrays.asList("Bill", "Bob", "Steve"));
