You can use String.format() to some extent. For example:

String.format("%07.3f", 1.23d); //prints 001.230

The format is %0<width>.<precision>f where, <width> is the minimum number of character (including the dot) that should be printed padded with 0's (in my example there are 7 characters); <precision> is the number of digits after the decimal point.

This method will work for simple formatting, and you cannot control the rounding (rounding is is half-up by default).
