public PrintfFormat(java.lang.String s)
```
    Formats a number in a printf format, like C.
    Parameters:
    s - the format string following printf format string The string has a prefix, a format code and a suffix. The prefix and suffix become part of the formatted output. The format code directs the formatting of the (single) parameter to be formatted. The code has the following structure
    
    a % (required)
    a modifier (optional)
    
    +
    forces display of + for positive numbers
    ~
    do not count leading + or - in length
    0
    show leading zeroes
    -
    align left in the field
    space
    prepend a space in front of positive numbers
    #
    use "alternate" format. Add 0 or 0x for octal or hexadecimal numbers; add 0b for binary numbers. Don't suppress trailing zeroes in general floating point format.
    ,
    groups decimal values by thousands (for 'diuxXb' formats)
    
    an integer denoting field width (optional)
    a period (.) followed by an integer denoting precision (optional)
    a format descriptor (required)
    
    f
    floating point number in fixed format,
    e, E
    floating point number in exponential notation (scientific format). The E format results in an uppercase E for the exponent (1.14130E+003), the e format in a lowercase e,
    g, G
    floating point number in general format (fixed format for small numbers, exponential format for large numbers). Trailing zeroes are suppressed. The G format results in an uppercase E for the exponent (if any), the g format in a lowercase e,.
    d, i
    signed long and integer in decimal,
    u
    unsigned long or integer in decimal,
    x
    unsigned long or integer in hexadecimal,
    o
    unsigned long or integer in octal,
    b
    unsigned long or integer in binary,
    s
    string (actually, toString() value of an object),
    c
    character,
    l, L
    boolean in lower or upper case (for booleans and int/longs),
    p
    identity hash code of an object (pointer :).

```
    Groups numbers by inserting 'separator' after every group of 'size' digits, starting from the right.
  - form
```
public java.lang.String form(char value)
```
    Formats a character into a string (like sprintf in C).
  - form
```
public java.lang.String form(boolean value)
```
    Formats a boolean into a string (like sprintf in C).
  - form
```
public java.lang.String form(double x)
```
    Formats a double into a string (like sprintf in C).
  - form
