It has the basically the same formatters as printf().
But they are type safe and can be used on streams.

Answer 3

Short answer: The Java equivalent is "%11.2f".

In C's printf() (but not scanf()), %f and %lf are equivalent; Both take a double argument.

In Java's Formatter.format(), %f is legal but %lf is not. %f works for Float, Double and BigDecimal values.
