The default package is an unnamed package. The unnamed package contains java classes whose source files did not contain a package declaration. The purpose of default package is for convenience when developing small or temporary applications or when just beginning development.The compiled class files will be in the current working directory.
There is no such thing as an access specifier in Java. There are access modifiers.The default access modifier if unspecified is to allow access to classes in the current package only, except within an interface where the default is 'public'
java.lang defines the core Java language, without which all of Java would fail to operate. It is therefore the default package that must be used with every program that will run Java, as it contains all of the logic necessary for exception handling, threads, classes that represent primitives (and their associated logic), and so on.
