What do you mean? Be specific

[ocean ore]

Booklisting makes the price of the book. It has 2 parameters

Thats the main class

[coarse spade]

"My program works fine without the class" => what do you mean?
"teacher likes to be annoying" => what do you mean?
"Iv tried [...] making book class its own parameter" => what do you mean?
And in theory you should have explained everything else, but I guess the main class explains it better

Is the main class something that you're forced to use as it is?

[ocean ore]

yes

book as well

In main the book listing news have two parameters but i cant figure out how you make an already existing book a parameter for book listing

[coarse spade]

Do you know how to make an already existing String a parameter for Book?

[ocean ore]

i tried that and it said you cant make the book class into a string

[coarse spade]

I didn't ask whether you tried something

I asked whether you know how to make an already existing String a parameter for Book

[ocean ore]

book is another one that int being changed

i ca only change book listing

[coarse spade]

I didn't ask what you can change

I asked whether you know how to make an already existing String a parameter for Book

[ocean ore]

yes i do

it doesnt work

[coarse spade]

I didn't ask whether something works

If you say you know, then please show

[ocean ore]

im not changing book

its perfect as is

[coarse spade]

So what you're saying is that no you don't know

So, here is how you make an already existing String a parameter for Book:

String title = "Frankestein";
String author = "Maty Shelley";
Book book1 = new Book(title, author);

[ocean ore]

I already said the book class is not being changed

its book listing that is causing issues

[coarse spade]

Yes, and that means you don't understand how it works

Because nothing here implies changing Book

[ocean ore]

all of that is already done

i know how it works

im trying to get that into book listing to use it

[coarse spade]

It works the same with BookListing, so no you don't know how it works

As a Book takes two parameters of type String and String

A BookListing takes two parameters of type Book and double

That is all

[ocean ore]

it wont let me use type book

[coarse spade]

What do you mean?

[ocean ore]

it doesnt work, it just gives errors

[coarse spade]

What - do - you - mean?

[ocean ore]

that making book a parameter doesnt work

[coarse spade]

What do you mean?

[ocean ore]

making book a parameter in book listing creates an error

[coarse spade]

Stop using fancy words

"making book a parameter" => What's that?

In other words, don't say anything but what you mean

[ocean ore]

i give up this is pointless. ill just wait until tomorrow for my teacher
