Dear,
I have a method and I want to call this method from another class but it throws me error:
can not find symbol method FindSellerNum(String)
I searched and I find that I need to put parenthesis for my argument, and I did + I need to start my method name by capital which I did.I also import my method "import booktrading.FindSellerNum;." but error is still there! is any thing else wrong hereI can't see?

here is the class code who calls method FindSellerNum:


and here is the method to be called:



can you please explain me why this error comes out or give me a good source
Thank you,
Sahar.

Create an Object for that class which has FindSellerNum method.



But you need to follow coding standard

Your method name is the same as the classname, which is not a good idea, unless this is the constructor class (which is not, since you return an int)

And, in general, method names should start with a lower-case letter, to avoid confusing people looking at your code. This is the typical Java coding standard for naming methods.

You could also make it a static method, and then not have to create the object. You'd still have to call it by referring to the class name, similar to how the Math class' methods work.


There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors
