Sybex - How many classes in a java file?

[Ioannis Gkinalas]

in page 5: "You can even put two classes in the same file. When you do so, at most one of the classes in the file is allowed to be public."
in page 6: "Each file can contain only one class."

Should page 6 rather say: "Each file can contain at least one public class."?

[Bear Bibeault]

Of what book?

[Jeanne Boyarsky]

Ioannis,
Welcome to CodeRanch!

I recognize that as being our book. Note that on the page 6, on the line before you quoted it says "To keep things simple for now, we'll follow a subset of the rules". Only one class is a subset at least one .

In other words, we are making a simpler world so you can focus on main methods() rather than how the complexities of classes.

Hope that helps.

Hi Bear and Jeanne, yes, the book is “OCA Oracle Certified Associate Java SE 8 Programmer” by J. Boyarsky and S. Sekikoff. Thank you Jeanne for you reply, however I don’t understand what you mean by "Only one class is a subset at least one".

I guess the question is what do you mean by "Each file can contain only one class" In page 6?

Many thanks and I wish you have a happy new year

Assume that on the pages that follow that sentence that there is only one class in a file.
