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.
But that won't work so well on Java 1.4+. Can't one just use: sb1.append(sb2); for both 1.3 and 1.4, and let the method do the work as needed? --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
