Stringbuffer 2005-10-23 - By Frans Verhoef

Hi,
You're actually asking the wrong question. The question is more how many
StringBuffer objects are created.
In method 1, 3 StringBuffer objects are created. One is the StringBuffer you
created yourself, but also each time you use the + to concatenate two string, a
StringBuffer is created by the JVM.
Therefore, in method 2, only one StringBuffer is created, as you append all
strings directly to your already existing StringBuffer, hence no extra
StringBuffers are need.
The amount of Strings created are the same, as in both cases only 4 strings are
generated ("beta", "The strings are ", "a", and "c").
Cheers,
Frans
