Consider the following coding that is developed to implement the Stack class of integers.

class stack $\{$

int stck $[]$;

int tos;

$//$ Initialize top$-$of$-$stack

Stack$($int arr$[])\{$

stck$=$arr;

tos $=-1$

$\}$

$//$ Push an item onto the stack

void push$($int item$)\{$

if $($tos$==9)$

System.out.println$("$Stack is ful$1.")$;

else

stck $[++$tos$]=$ item;

$\}$

$//$ Pop an item from the stack

int pop$()\{$

if $($tos $<mn\; id="EditorElement\_3909702">0</mn><mi\; id="EditorElement\_3909703">)</mi><mtext\; id="EditorElement\_3909704"></mtext><mi\; id="EditorElement\_3909705">\{</mi>$

System.out.println$("$Stack underflow."$)$;

return $0$ ;

e$1$se

$\}$

return stck$[$tos$--]$;

$\}$

$\}$

We are now interested to make an interface StackInterface that has functionally to push and

pop with a generic datatype T$.$ Modify the class Stack that will implement StackInterface.

Also, in the driver class make stacks of integer, double and push and pop $3$ items of each category

in the stacks.
