Marcus Green's Exam #1 Question 59

[Kevin Cary]

I remember that each source file must have a public top level class yet the below example works. How is this possible?
class Base{
private void amethod(int iBase){
System.out.println("Base.amethod");
}
}
class Over extends Base{
public static void main(String argv[]){
Over o = new Over();
int iBase=0;
o.amethod(iBase);
}
public void amethod(int iOver){
System.out.println("Over.amethod");
}
}

Hi,
Your memory is failing you ... The correct quote is:

A Java source file can contain AT MOST one public top level class.

Therefore even an empty file is a valid Java source file.
Regards,
Manfred.

Thanks for your help Manfred. This certainly clears my confusion.

hi kevin
The question is perfectly right and answer too.
The Top-Level classes can be public or can have a default modifier.

Hi Sandeep,
I your message seems to say a top level class can be public or default. For clarification, I think a top level class can have the attributes, public, protected, or default but not private. Is this correct?

Sorry about this last post. The mistake is mine. A top level class can either public or default.
