Write

the

Java

program

and

a

test

plan

for

the

following

problem:

A

printing

shop

would

like

to

be

able

to

know

when

to

re--‐order

paper.

The

paper

used

by

the

shop

comes

in

packages

of

500

pages

each.

You

have

been

asked

to

create

a

prototype

program

for

this

problem.

The

program

should

ask

the

user

to

enter

the

number

of

packages

of

paper

in

stock,

how

many

pages

are

in

the

document

to

be

printed,

and

how

many

copies

are

to

be

made.

The

output

from

the

program

should

be

the

number

of

packages

of

paper

that

will

remain

after

the

printing

is

completed.-Algorithm:



Get stock package

Get document page

Get copy amount



The print page = document page* copy amount

If print page 500　=0 use used package= print page/500

If print page 500! =0 use used package= print page/500+1

Left package = stock package – print package

Output left package
