/** {@collect.stats}
* {@description.open}
* Provides classes that are fundamental to the design of the Java
* programming language. The most important classes are {@code
* Object}, which is the root of the class hierarchy, and {@code
* Class}, instances of which represent classes at run time.
*
* <p>Frequently it is necessary to represent a value of primitive
* type as if it were an object. The wrapper classes {@code Boolean},
* {@code Character}, {@code Integer}, {@code Long}, {@code Float},
* and {@code Double} serve this purpose. An object of type {@code
* Double}, for example, contains a field whose type is double,
* representing that value in such a way that a reference to it can be
* stored in a variable of reference type. These classes also provide
* a number of methods for converting among primitive values, as well
* as supporting such standard methods as equals and hashCode. The
* {@code Void} class is a non-instantiable class that holds a
* reference to a {@code Class} object representing the type void.
*
* <p>The class {@code Math} provides commonly used mathematical
* functions such as sine, cosine, and square root. The classes {@code
* String}, {@code StringBuffer}, and {@code StringBuilder} similarly
* provide commonly used operations on character strings.
*
* <p>Classes {@code ClassLoader}, {@code Process}, {@code
* ProcessBuilder}, {@code Runtime}, {@code SecurityManager}, and
* {@code System} provide "system operations" that manage the dynamic
* loading of classes, creation of external processes, host
* environment inquiries such as the time of day, and enforcement of
* security policies.
*
* <p>Class {@code Throwable} encompasses objects that may be thrown
* by the {@code throw} statement. Subclasses of {@code Throwable}
* represent errors and exceptions.

* <h3>Character Encodings</h3>
*
* The specification of the {@link java.nio.charset.Charset
* java.nio.charset.Charset} class describes the naming conventions
* for character encodings as well as the set of standard encodings
* that must be supported by every implementation of the Java
* platform.
