public class InputStreamReader

  1. Object
  2. Reader
  3. InputStreamReader

ImplementsAutoCloseable

An InputStreamReader is a bridge from byte streams to character streams: It reads bytes and translates them into characters. The encoding that it uses may be specified by name, or the platform’s default encoding may be accepted. Each invocation of one of an InputStreamReader’s read() methods may cause one or more bytes to be read from the underlying byte input stream. To enable the efficient conversion of bytes to characters, more bytes may be read ahead from the underlying stream than are necessary to satisfy the current read operation. Since: CLDC 1.0 See Also:Reader, UnsupportedEncodingException

Constructors

public InputStreamReader(InputStream is)Create an InputStreamReader that uses the default character encoding.
public InputStreamReader(InputStream is, String enc) throws UnsupportedEncodingExceptionCreate an InputStreamReader that uses the named character encoding.

Methods

public void close() throws IOExceptionClose the stream.
public void mark(int readAheadLimit) throws IOExceptionMark the present position in the stream.
public boolean markSupported()Tell whether this stream supports the mark() operation.
public int read() throws IOExceptionRead a single character.
public int read(char[] cbuf, int off, int len) throws IOExceptionRead characters into a portion of an array.
public boolean ready() throws IOExceptionTell whether this stream is ready to be read.
public void reset() throws IOExceptionReset the stream.
public long skip(long n) throws IOExceptionSkip characters.

Throws

IOException

read

public int read(char[] cbuf, int off, int len) throws IOException
