Cannot make a static reference to the non static method draw() in the type myStockProject.draw

smep · April 6, 2020, 1:58pm

I’ve been creating a stock market and I am unable to figure a solution to the error in the title.
at the point graph.draw in the class myStockProject is where I get the error. I have uploaded that class and the graph class. any help or solutions would be appreciated.

We can’t run your code, a lot of classes are missing

The error you get is mostly cause by lines of code outside any function. This is mostly a misplaced } …

I couldn’t find any, but it can be in another tab if you have those

Hello,

I always take an interest but your code is not formatted (difficult to read and can’t cut and paste) so have to pass on this one.

Try doing a Google search; there are many discussions on this topic and you may glean some insight from them.

:)

I was wrong with my assessment

Forget about it
