Answer 1

See,
all the classes in the package java.lang are imported by itself and you don't have to import for using any classes in the java.lang package.
Since "_Integer_" is a class in the java.lang package compiler was able to find it .
Now in your second case when you are writing PkgAccess.tiger,compiler needs to find PkgAcess class but unfortunately it won't be able to find it because you have not imported the package.
import static com.sun.PkgAccess.*;
This statement only imports the static fields of the PkgAcess class and not the class.So for it to compile successfully you should import the class by writing
import com.sun.PkgAccess;
I hope you understood.This was my first attempt to explain something to someone.
