Method Detail- 
readpublic int read() throws java.io.IOExceptionDeprecated.Read a single character. This method will block until a character is available, an I/O error occurs, or the end of the stream is reached.Subclasses that intend to support efficient single-character input should override this method. - Overrides:
- readin class- java.io.Reader
- Returns:
- The character read, as an integer in the range 0 to 127
             (0x00-0x7f), or -1 if the end of the stream has been reached
- Throws:
- java.io.IOException- If an I/O error occurs
 
 - 
readpublic int read(char[] ch, int offset, int length) throws java.io.IOExceptionDeprecated.Read characters into a portion of an array. This method will block until some input is available, an I/O error occurs, or the end of the stream is reached.- Specified by:
- readin class- java.io.Reader
- Parameters:
- ch- Destination buffer
- offset- Offset at which to start storing characters
- length- Maximum number of characters to read
- Returns:
- The number of characters read, or -1 if the end of the stream has been reached
- Throws:
- java.io.IOException- If an I/O error occurs
 
 - 
skippublic long skip(long n) throws java.io.IOExceptionDeprecated.Skip characters. This method will block until some characters are available, an I/O error occurs, or the end of the stream is reached.- Overrides:
- skipin class- java.io.Reader
- Parameters:
- n- The number of characters to skip
- Returns:
- The number of characters actually skipped
- Throws:
- java.io.IOException- If an I/O error occurs
 
 - 
readypublic boolean ready() throws java.io.IOExceptionDeprecated.Tell whether this stream is ready to be read.- Overrides:
- readyin class- java.io.Reader
- Returns:
- True if the next read() is guaranteed not to block for input, false otherwise. Note that returning false does not guarantee that the next read will block.
- Throws:
- java.io.IOException- If an I/O error occurs
 
 - 
markSupportedpublic boolean markSupported() Deprecated.Tell whether this stream supports the mark() operation.- Overrides:
- markSupportedin class- java.io.Reader
 
 - 
markpublic void mark(int readAheadLimit) throws java.io.IOExceptionDeprecated.Mark the present position in the stream. Subsequent calls to reset() will attempt to reposition the stream to this point. Not all character-input streams support the mark() operation.- Overrides:
- markin class- java.io.Reader
- Parameters:
- readAheadLimit- Limit on the number of characters that may be read while still preserving the mark. After reading this many characters, attempting to reset the stream may fail.
- Throws:
- java.io.IOException- If the stream does not support mark(), or if some other I/O error occurs
 
 - 
resetpublic void reset() throws java.io.IOExceptionDeprecated.Reset the stream. If the stream has been marked, then attempt to reposition it at the mark. If the stream has not been marked, then attempt to reset it in some way appropriate to the particular stream, for example by repositioning it to its starting point. Not all character-input streams support the reset() operation, and some support reset() without supporting mark().- Overrides:
- resetin class- java.io.Reader
- Throws:
- java.io.IOException- If the stream has not been marked, or if the mark has been invalidated, or if the stream does not support reset(), or if some other I/O error occurs
 
 - 
closepublic void close() throws java.io.IOExceptionDeprecated.Close the stream. Once a stream has been closed, further read(), ready(), mark(), or reset() invocations will throw an IOException. Closing a previously-closed stream, however, has no effect.- Specified by:
- closein interface- java.lang.AutoCloseable
- Specified by:
- closein interface- java.io.Closeable
- Specified by:
- closein class- java.io.Reader
- Throws:
- java.io.IOException- If an I/O error occurs
