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.
No, I'm not endorsing the APIs provided, at least for now:-) there is
room to debate what would be
the best choice(APIs) to support the "joint", if we decided to add one.
Is it more clear now ?
By the way, I've written 3 tests, one by class (String, StringBuilder,
StringBuffer)
Should I add them to the webrev ?
