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

StringBuffer is final. You cannot derive from it. The Best solution really is to add the padding for yourself. Write a method for it and use a PADDING-Constant so that you can easily change it, or better put it in a parameter.
