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

Code you have is right way to do it if you want to do using JDK without any external libraries. There is no simple "one-liner" that you could use in JDK.

If you can use external libs, I recommend that you look into org.apache.commons.lang.StringUtils class in Apache Commons library.

An example of usage:

List list = Arrays.asList("Bill", "Bob", "Steve");
String joinedResult = StringUtils.join(list, " and ");
