NET framework handles strings very nicely - but it takes some getting used to. StringBuilder (a buffer) solves this problem. This cannot be done with the usual –Xms(set initial heap size) and –Xmx(set maximum heap size) JVM arguments, since as mentioned, the permanent generation heap space is entirely separate from the regular Java Heap space, and these arguments set the space for this regular Java heap space.
