| BufferedReader |
BufferedReader is a buffered character input reader. |
| CharArrayReader |
CharArrayReader is used as a buffered character input stream on a character
array. |
| CharBuffer |
A buffer of chars. |
| FileReader |
FileReader is class for turning a file into a character Stream. |
| FilterReader |
FilterReader is a class which takes a Reader and filters the input
in some way. |
| InputStreamReader |
InputStreamReader is class for turning a byte Stream into a character Stream. |
| LineNumberReader |
LineNumberReader is a buffered character input reader which counts line
numbers as data is being read. |
| PipedReader |
PipedReader is a class which receives information on a communications pipe. |
| PushbackReader |
PushbackReader is a filter class which allows chars read to be pushed back
into the stream so that they can be reread. |
| Reader |
Reader is an Abstract class for reading Character Streams. |
| StringReader |
StringReader is used as a character input stream on a String. |
