A package is a namespace that mainly contains classes and interfaces. For instance, the standard class `ArrayList` is in the package `java.util`. For this class, `java.util.ArrayList` is called its fully qualified name because this syntax has no ambiguity. Classes in different packages can have the same name. For example, you have the two classes `java.util.Date` and `java.sql.Date`, which are different. If no package is declared in a class, its package is the default package.

The Java Virtual Machine is a program whose purpose is to execute other programs. JVMs are available for many hardware and software platforms (i.e. JVM is platform dependent). JVM is the one that actually calls the main method present in a java code. JVM is a part of JRE(Java Runtime Environment)
