Surely a StringBuffer is already an Object?
Or am I missing something here?
StringBuffer has a new method in Java 1.4 to append another Stringbuffer
without invoking it's toSring() method.
Code that uses StringBuffer.append(stb) and compiled by a JDK 1.4 will
not work on Java 1.3.
I miself recommand Using "StringBuffer.append(stb.toString())" that
looks better than an apparently useless (Object) cast : checkstyle or
IDE may warn for unecessary cast.
Also may be a solution, which looks more readable. Though I fixed all these StringBuffer issues I
had personally by adding the not very useless Object cast (this way you prevent the usage of the
overloaded method which takes a StringBuffer). This way I don't have to worry whats under the covers
, which in this case is according to you a toString().
