Is there a direct equivalent in Java for Python's str.join? [duplicate]

What’s the best way to build a string of delimited items in Java?
Java: convert List<String> to a join()d string

In Java, given a collection, getting the iterator and doing a separate case for the first (or last) element and the rest to get a comma separated string seems quite dull, is there something like str.join in Python?

Extra clarification for avoiding it being closed as duplicate: I'd rather not use external libraries like Apache Commons.

Thanks!

Java 8 came to the rescue

Nope there is not. Here is my attempt:

/**  * Join a collection of strings and add commas as delimiters.  * @require words.size() > 0 && words != null  */ public static String concatWithCommas(Collection<String> words) {     StringBuilder wordList = new StringBuilder();     for (String word : words) {         wordList.append(word + ",");     }     return new String(wordList.deleteCharAt(wordList.length() - 1)); }
