Character Streams versus Byte Streams

The following table summarizes the character stream classes. In the left column, indentation indicates subclass relationships.

Character-stream class Description Corresponding byte class
Reader Abstract class for character-input streams InputStream
    BufferedReader Buffers input, parses lines BufferedInputStream
        LineNumberReader     Keeps track of line numbers LineNumberInputStream
    CharArrayReader Reads from a character array
    InputStreamReader Translates a byte stream into a character stream (none)
        FileReader Translates bytes from a file into a character stream     FileInputStream
    FilterReader Abstract class for filtered character input FilterInputStream
        PushbackReader Allows characters to be pushed back PushbackInputStream
    PipedReader Reads from a PipedWriter PipedInputStream
    StringReader Reads from a String StringBufferInputStream
 
Writer Abstract class for character-output streams OutputStream
    BufferedWriter Buffers output, uses platform's line separator BufferedOutputStream
    CharArrayWriter Writes to a character array ByteArrayOutputStream
    FilterWriter Abstract class for filtered character output FilterOutputStream
    OutputStreamWriter Translates a character stream into a byte stream (none)
        FileWriter Translates a character stream into a byte file FileOutputStream
    PrintWriter Prints values and objects to a Writer PrintStream
    PipedWriter Writes to a PipedReader PipedOutputStream
    StringWriter Writes to a String (none)
