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"? 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. Sherman Rémi Forax wrote:
Hi all, bug 5015163 is a RFE that advocate to add a method join (like in Python) to String/StringBuilder/StringBuffer.
Here is the corresponding webrev (using the new infrastucture :) http://cr.openjdk.java.net/~forax/5015163/webrev.00/ The patch is against tl repository.
Who want to review it ?
For the record, i have previously proposed this fix using the jdk-collaboration forum more than one year ago but because i am lazy i haven't take the time to post it here.
cheers, Rémi Forax
