Answer by Dan Dyer for How do I create a Java string from the contents of a file?

There is a variation on the same theme that uses a for loop, instead of a while loop, to limit the scope of the line variable. Whether it's "better" is a matter of personal taste.

for(String line = reader.readLine(); line != null; line = reader.readLine()) {    stringBuilder.append(line);    stringBuilder.append(ls);}
