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

You can do this:

String aToString = java.util.Arrays.toString(anArray);
// Do not need to do this if you are OK with '[' and ']'
aToString = aToString.substring(1, aToString.length() - 1);

Or a one-liner (only when you do not want '[' and ']')

String aToString = java.util.Arrays.toString(anArray).substring(1).replaceAll("\\]$", "");

Hope this helps.
