Because the language specification requires it.
Chapter*7.*Packages

A compilation unit automatically has access to all types declared in its package and also automatically imports all of the public types declared in the predefined package java.lang.

The compiler does it all for you, there's no need to worry about it, because it is defined that way (see Darryl's reply)

kind regards,

And if you're trying to add your own classes to the "default package", I doubt that's possible.

That will be compiler implementation specific.
The specification merely requires that it be automatically imported without a class having to do it itself.
