## Uses of Class
java.io.FilterInputStream

Packages that use FilterInputStream
java.io: Provides for system input and output through data streams, serialization and the file system.
java.security: Provides the classes and interfaces for the security framework.
java.util.jar: Provides classes for reading and writing the JAR (Java ARchive) file format, which is based on the standard ZIP file format with an optional manifest file.
java.util.zip: Provides classes for reading and writing the standard ZIP and GZIP file formats.
javax.crypto: Provides the classes and interfaces for cryptographic operations.
javax.swing: Provides a set of "lightweight" (all-Java language) components that, to the maximum degree possible, work the same on all platforms.

### Uses of FilterInputStream in java.io

Subclasses of FilterInputStream in java.io
`class` `BufferedInputStream` A `BufferedInputStream` adds functionality to another input stream-namely, the ability to buffer the input and to support the `mark` and `reset` methods.
`class` `DataInputStream` A data input stream lets an application read primitive Java data types from an underlying input stream in a machine-independent way.
`class` `LineNumberInputStream` Deprecated. This class incorrectly assumes that bytes adequately represent characters. As of JDK 1.1, the preferred way to operate on character streams is via the new character-stream classes, which include a class for counting line numbers.
`class` `PushbackInputStream` A `PushbackInputStream` adds functionality to another input stream, namely the ability to "push back" or "unread" bytes, by storing pushed-back bytes in an internal buffer.

### Uses of FilterInputStream in java.security

Subclasses of FilterInputStream in java.security
`class` `DigestInputStream` A transparent stream that updates the associated message digest using the bits going through the stream.

### Uses of FilterInputStream in java.util.jar

Subclasses of FilterInputStream in java.util.jar
`class` `JarInputStream` The `JarInputStream` class is used to read the contents of a JAR file from any input stream.

### Uses of FilterInputStream in java.util.zip

Subclasses of FilterInputStream in java.util.zip
`class` `CheckedInputStream` An input stream that also maintains a checksum of the data being read.
`class` `DeflaterInputStream` Implements an input stream filter for compressing data in the "deflate" compression format.
`class` `GZIPInputStream` This class implements a stream filter for reading compressed data in the GZIP file format.
`class` `InflaterInputStream` This class implements a stream filter for uncompressing data in the "deflate" compression format.
`class` `ZipInputStream` This class implements an input stream filter for reading files in the ZIP file format.

### Uses of FilterInputStream in javax.crypto

Subclasses of FilterInputStream in javax.crypto
`class` `CipherInputStream` A CipherInputStream is composed of an InputStream and a Cipher so that read() methods return data that are read in from the underlying InputStream but have been additionally processed by the Cipher.

### Uses of FilterInputStream in javax.swing

Subclasses of FilterInputStream in javax.swing
`class` `ProgressMonitorInputStream` Monitors the progress of reading from some InputStream.
