readable closeable

This class is a character input stream that keeps track of the number of lines of text that have been read from it. It supports the usual Reader methods and also the readLine( ) method introduced by its superclass. In addition to these methods, you can call getLineNumber( ) to query the number of lines set so far. You can also call setLineNumber( ) to set the line number for the current line. Subsequent lines are numbered sequentially from this specified starting point. This class is a character-stream analog to LineNumberInputStream , which has been deprecated as of Java 1.1.
