The supermost package of Java is the "java" package.
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.
