Re: Composing Strings
May 3rd, 2003
I got a nice reaction on Composing Strings, from somebody who apparently wants to remain anonymous:
StringBuffer sb = new StringBuffer();This answers all the criteria of the problem. Alas, readability wasn't one of them (as noted by himself, BTW).
for (Iterator it = list.iterator(); it.hasNext(); sb.append(it.hasNext()?"and":"")) {
sb.append(it.next().toString());
}
So does atog's solution, which is more readable, but I still feel it as a waste of energy to add things, and then take them away again. Maybe I'm just being stubborn on this.
And no, Java has no String.join() operation as one kind soul suggested in the comments. Looks like something for Yet Another Util Package.
