| BufferedReader |
Reads text from a character-input stream, buffering characters so as to
provide for the efficient reading of characters, arrays, and lines.
|
| CharArrayReader |
This class implements a character buffer that can be used as a
character-input stream.
|
| CharBuffer |
A char buffer.
|
| FileReader |
Convenience class for reading character files.
|
| FilterReader |
Abstract class for reading filtered character streams.
|
| InputStreamReader |
An InputStreamReader is a bridge from byte streams to character streams: It
reads bytes and decodes them into characters using a specified charset |
| LineNumberReader |
A buffered character-input stream that keeps track of line numbers.
|
| PipedReader |
Piped character-input streams.
|
| PushbackReader |
A character-stream reader that allows characters to be pushed back into the
stream.
|
| Reader |
Abstract class for reading character streams.
|
| StringReader |
A character stream whose source is a string.
|
|
A Readable is a source of characters. Characters from
a Readable are made available to callers of the read
method via a CharBuffer.

Public methods
read
int read (CharBuffer cb)
Attempts to read characters into the specified character buffer.
The buffer is used as a repository of characters as-is: the only
changes made are the results of a put operation. No flipping or
rewinding of the buffer is performed.
| Parameters |
|---|
cb |
CharBuffer:
the buffer to read characters into |
| Returns |
|---|
int |
The number of char values added to the buffer,
or -1 if this source of characters is at its end |
