"Write a no$-$arg constructor for this class. It should assign the sideLength field the value $0\mathrm{.}0.$

a

public Square$()$

$\{$

sideLength $=$ void;

b

public Square$()$

$\{$

sideLength $=0\mathrm{.}0$;

$\}$

c

public Square$()$

$\{$

sideLength $=$ zero;

d

public Square$(0\mathrm{.}0)$
