class outside of its source file

[haagen]

Hi,

I use a class called OKFrame in a file that does not contained it
and I have this error message:


src/jade/grassplot/OxGrid.java:55: class jade.grassplot.OKFrame
is defined in MapSetPick.java. Because it is used outside of its
source file, it should be defined in a file called "OKFrame.java".
OKFrame ok = new OKFrame();
^


I tried to import the file where my class is in the file where
I want to use it but it doesn't work, and I don't know why I
should defined my class alone in a file.

Thanks a lot

From what I can see, you are not trying to USE the class OKFrame in this
file. You are trying to DEFINE it there. Why should you define your class
alone in its own file? Because that's the rule in Java. Create a file
called OKFrame.java, as the message says, and put the code for the class
OKFrame in it. The file MapSetPick.java should contain only the class
MapSetPick; it can create objects of class OKFrame if you like.
