Consider the definition of the following class:

public class CC

$\{$

private int $u$;

private int $v,$

private double $w_{\text{;}}$

public CC$()$

$\frac{\frac{?}{?}}{?}$ Line $1$

$\{dots\}$

public CC$($int a$)$

$\frac{\frac{?}{?}}{?}$ Line $2$

$\{dots\}$

public int $a,$ int b$)$

$\frac{\frac{?}{?}}{?}$ Line $3$

$\{dots\}$

public CC$($int a$,$ int b$,$ double d$)//$Line $4$

$\{dots\}$

a$.$ Give the line number containing the constructor that is executed in each of the following

declarations:

$($i$)CC$ one $=$ new $CC()$;

$($ii$)CC$ two $=$ new $CC(5,6)$;

$($iii$)CC$ three $=$ new $CC(2,8,3\mathrm{.}5)$;

b$.$ Write the definition of the constructor in Line $1$ so that the instance variables are

initialized to $0.$
