Ref

[compact saffron]

wasn't it working in your third picture ?

[cinder haven]

no one's going to be able to answer this to your satisfaction without explaning how fundamental logic works, the same logic you already know and use

[weary whale]

how does it work?

[cinder haven]

how does... what work, a definition? are you asking about the internal structure or what

[compact saffron]

I'm confused what you are asking me right now. How does what work ?

[weary whale]

how did this:

[jagged granite]

class Student { int rollno; String name; int marks; }

oh my god we're going in circles

[compact saffron]

because you defined what a Student is. Before you were just telling the compiler to use the type Student however, the compiler had no idea what student was because there is no class defined for it.

[cinder haven]

inb4 exact same thing happens as last thread 🍿

[weary whale]

that's the purpose of classes?

to define variables?

[compact saffron]

classes are a structure. They logically bundle variables and methods together

check this out buddy

i remember you asking questions here, you were so much farther along, what happened

[weary whale]

wonder if there's a way to define the variables under class array6

or do I always have to create separate classes?

and are there other options to define variables?

[cinder haven]

ah love it when you're blocked from giving links

@compact saffron just resend the link i gave it'll probably work lmao

[compact saffron]

you should always group variables and methods in logical bundles aka classes. If you have a class that has hundreds of responsibilities and variables to keep track of nobody, including you, is going to understand what you are coding. I wholeheartedly recommend the link above, the article will get you started with the basics.

[cinder haven]

he's not gonna see the link just resend it

[weary whale]

alright thanks
