 Many methods in the standard library create strings. As a example: ''java/lang/Integer.toString'' or ''java/lang/Integer.toHexString'' create a new string object every time the are called. This first takes a considerable time and creates garbage. Do not use such methods if not absolutely necessary. For printing to serial output devices, it's much more efficient to use the methods in ''java/io/PrintStream''. They reuse existing strings. Many methods in the standard library create strings.
