Java：转换列表 <String> 到一个字符串

问题：

JavaScript has Array.join() JavaScript具有Array.join()

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

Does Java have anything like this? Java有这样的东西吗？ I know I can cobble something up myself with StringBuilder: 我知道我可以使用StringBuilder自己整理一些东西：

static public String join(List<String> list, String conjunction)
{
   StringBuilder sb = new StringBuilder();
   boolean first = true;
   for (String item : list)
   {
      if (first)
         first = false;
      else
         sb.append(conjunction);
      sb.append(item);
   }
   return sb.toString();
}

...but there's no point in doing this if something like it is already part of the JDK. ...但是如果类似的东西已经成为JDK的一部分，那么这样做是没有意义的。
