Java: StringBuffer & Concatenation

Question

I\'m using StringBuffer in Java to concat strings together, like so:

StringBuffer str = new StringBuffer();

str.append(\"string value\");

Answer 1

Another possibility is that StringBuilder objects return themselves when you call append, meaning you can do:

str.append("string value").append(" ");

Not quite as slick, but it is probably an easier solution than the + " " method.

Another possibility is to build a wrapper class, like PaddedStringBuilder, that provides the same methods but applies the padding you want, since you can't inherit.
