Given the Java code below $($and attached to the email as a $.$zip file$)$ from the producer$-$consumer

problem, change it so the code no longer uses Generics $($which are called Templates in $C++)$ but

instead uses Integer, and replace the arrays with ArrayList. Have the user input the buffer size

at run time to match with the use of ArrayList instead of an array. Add a value$-$pass constructor

that accepts values for count, in$,$ out, and sets the size of the array $($which will be changed to an

ArrayList$).$ Modify the code so it no longer implements an interface. No main needed.

BufferImpl.java:

public class BufferImpl implements Buffer

$\{$

private static final int BUFFER$\_$SIZE $=5$;

private E$[]$ elements;

private int in$,$ out, count;

public BufferImpl$()\{$

count $=0$;

in $=0$;

out $=0$;

elements $=($E$[])$ new Object$[$BUFFER$\_$SIZE$]$;

$\}$

$//$ producers call this method

public void insert$($E item$)\{$

while $($count $==$ BUFFER$\_$SIZE$)$

; $//$ do nothing $--$ no free space

$//$ add an element to the buffer

elements$[$in$]=$ item;

in $=($in $+1)\%$ BUFFER$\_$SIZE;

$++$count;

$\}$

$//$ consumers call this method

public E remove$()\{$

E item;

while $($count $==0)$

; $//$ do nothing $-$ nothing to consume

$//$ remove an item from the buffer

item $=$ elements$[$out$]$;

out $=($out $+1)\%$ BUFFER$\_$SIZE;

$--$count;

return item;

$\}$

$\}$

Buffer.java:

public interface Buffer

$\{$

public void insert$($E item$)$;

public E remove$()$;

$\}$
