OCR: Class Description BufferedinputStream Buffers input data. An internal buffer of arbitrary length is filled with data. Consolidates multiple disk reads by filling an internal buffer less frequently than multiple reads to normal InputStreams would. LineNumberInputStream Example of a simple odometer-type input filter, Keeps track of the number of newline characters that have been read or skipped over PushbackInputStream Simple filter that allows you to push back a single character into the input stream. That is, you can read a character from the stream, push if back into to stream, then read it again. The maximum pushback depth of a PushbackinputStream is one character. DatainputStream Has methods such as readBoolean and readint that combine bytes into built-in data-type values. SequenceinputStream Strings a sequence of input streams together as if they were all a single input stream. Figure 4: The FilteredInputStream classes included in the java.lo package
