What is LineNumberInputStream In Java ?

Class LineNumberInputStream

All Implemented Interfaces:

Closeable, AutoCloseable

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.

@Deprecated

public class LineNumberInputStream

extends FilterInputStream

LineNumberInputStream class is an input stream filter that provides the added functionality of keeping track of the current line number.

A line is a sequence of bytes ending with a carriage return character ('\r'), a newline character ('\n'), or a carriage return character followed immediately by a linefeed character. In all three cases, the line terminating character(s) are returned as a single newline character.

The line number begins at 0, and is incremented by 1 when a read returns a newline character.
