"public class MyClass{ }
There can be only 1 "public" class within package scope in a file. You can have additional inner classes that are public though."
Why? I wrote this code
"package myPackedjedsccsdcscsdscd;
public class Test1{}
public class Test{
public static void main(String[] args){
System.out.println("Iworking!!!");
}
} "
in Eclipse and he work.

You should not worry about what Eclipse or any IDE does. As per the specification there can be at most one public class in a file. So that is what you should remember for the exam.

try to create an instance of Test1 and you will get an exception ....

I think that you should specify in the question that the file is only one.
If the file were different the option £public class MyClass{ }" would correct also.

how it is valid p.util package statement

Not sure what you are asking. Could you please explain?

So in a file we can have interfaces, abstract classes and one public class.
or can we have public abstract class and inner class non public.

You can have at most one public "thing" in a file at package score. It can be a class, an interface, or an enum. You can have multiple public inner classes.

You can also try it out to confirm.

Hi there,
how it is valid p.util package statement of option 2?
Can anyone explain it?
thanks in advance

Well, a class can belong to any package. So, you can write a package statement at the top of the java file to specify the package name. Not sure what is the confusion here.

Thanks for your reply

we know that class can belong to any package but how comes p?
Is it fixed to take p or any other alphabets can we take?
or share link of any resources

Thanks

A package name can be anything as long as it follows the rules of an identifer.
