Define a Pair class using Java Generics framework $(40$ points$)$

a$.$ Properties: first, second

b$.$ Constructors: Create $2$ different constructor with different initialization parameters

c$.$ Methods: setFirst$(),$ setSecond$(),$ getFirst$(),$ getSecond$()$;

d$.$ Test Pair class print out the value of Pair instance:

i$.$ Define a Pair instance and assign $(10,10\mathrm{.}1)$ to the pair;

ii$.$ Define a Pair instance and assign $(8\mathrm{.}2,$ABC$)$ to the pair;

iii. Define an array holding$[]$ of Pair class.

$1.$ holding has $100$ elements;

$2.$ Assign $($int$,$ double$)$ to array by using loop $->(0,100\mathrm{.}0),(1,99\mathrm{.}0),(2,98\mathrm{.}0),...,$

$(99,1\mathrm{.}0$
