Xueming Shen a écrit :public String join(Object first, Object... elements) { if (elements.length==0) return String.valueOf(first); return new StringBuilder().join(this, first, elements).toString(); }It does not look right to simply return String.valueOf(first); when elements size is 0, where is "this"?"this" is the delimiter. ",".join("hello", "world") => "hello,world" Thus it doesn't use "this" if there is only one argument.
oops, did not pay attention to the "deimiter part:-)
