## Uses of Interface
java.lang.Comparable

Packages that use Comparable
java.io | Provides for system input and output through data streams, serialization and the file system.
java.lang | Provides classes that are fundamental to the design of the Java programming language.
java.math | Provides classes for performing arbitrary-precision integer arithmetic (BigInteger) and arbitrary-precision decimal arithmetic (BigDecimal).
java.net | Provides the classes for implementing networking applications.
java.nio | Defines buffers, which are containers for data, and provides an overview of the other NIO packages.
java.nio.charset | Defines charsets, decoders, and encoders, for translating between bytes and Unicode characters.
java.sql | Provides the API for accessing and processing data stored in a data source (usually a relational database) using the JavaTM programming language.
java.text | Provides classes and interfaces for handling text, dates, numbers, and messages in a manner independent of natural languages.
java.util | Contains the collections framework, legacy collection classes, event model, date and time facilities, internationalization, and miscellaneous utility classes (a string tokenizer, a random-number generator, and a bit array).

Uses of Comparable in java.io

Classes in java.io that implement Comparable
`class` | `File` An abstract representation of file and directory pathnames.
`class` | `ObjectStreamField` A description of a Serializable field from a Serializable class.

Uses of Comparable in java.lang

Classes in java.lang that implement Comparable
`class` | `Byte` The `Byte` class wraps a value of primitive type `byte` in an object.
`class` | `Character` The `Character` class wraps a value of the primitive type `char` in an object.
`class` | `Double` The `Double` class wraps a value of the primitive type `double` in an object.
`class` | `Float` The `Float` class wraps a value of primitive type `float` in an object.
`class` | `Integer` The `Integer` class wraps a value of the primitive type `int` in an object.
`class` | `Long` The `Long` class wraps a value of the primitive type `long` in an object.

Uses of Comparable in java.nio.charset

Classes in java.nio.charset that implement Comparable
`class` | `Charset` A named mapping between sequences of sixteen-bit Unicode characters and sequences of bytes.

Uses of Comparable in java.sql

Classes in java.sql that implement Comparable
`class` | `Time` A thin wrapper around the `java.util.Date` class that allows the JDBC API to identify this as an SQL `TIME` value.
`class` | `Timestamp` A thin wrapper around `java.util.Date` that allows the JDBC API to identify this as an SQL `TIMESTAMP` value.

Uses of Comparable in java.text

Classes in java.text that implement Comparable
`class` | `CollationKey` A `CollationKey` represents a `String` under the rules of a specific `Collator` object.

Uses of Comparable in java.util

Classes in java.util that implement Comparable
`class` | `Date` The class `Date` represents a specific instant in time, with millisecond precision.
