The method is not static So you need to call it on an instance of the class You create one such instance on the line above

it is a project due on saturday so i have to do this for 20% of my grade
A
Angius•17d ago
And, to answer your question, if a method says it wants some parameter, you gice it that parameter This method wants an instance of UserDetails, so you should give it one
E
Eve.•17d ago
what does instance mean like to define it?
A
Angius•17d ago
No idea how to define it besides "instance is an instance" You instantiate classes with new What you get from new Foo() is an instance of class Foo
E
Eve.•17d ago
ahh okay @jiniux can you help me
J
jiniux•17d ago
what is the problem?
E
Eve.•17d ago
at the top idk how to fix it at all
A
Angius•17d ago
I told you exactly how?
E
Eve.•17d ago
idk what instanciate means idk what to instanciate and idk where or what class
A
Angius•17d ago
So you resorted to pinging random people instead of asking lmao
J
jiniux•17d ago
probably pinged me because i helped them some days ago
A
Angius•17d ago
To isntantiate means to create an instance You have all the necessary instances of all the necessary classes already made You even called the correct method on the correct instance Now, the method only needs a parameter You have the instance needed for that already This one Now just pass it as a parameter to your method
E
Eve.•17d ago
idk how to do that
A
Angius•17d ago
Method(parameter)
