24.3 java.io.BufferedReader (JDK 1.1)

This class applies buffering to a character input stream, thereby improving the efficiency of character input. You create a BufferedReader by specifying some other character input stream that it is to buffer input from. (You can also specify a buffer size at this time, although the default size is usually fine.) Typically you use this sort of buffering when you are using a FileReader or InputStreamReader.

BufferedReader defines the standard set of Reader methods, and also provides a readLine() method that reads a line of text (not including the line-terminators) and returns it as a String.

BufferedReader is the character-stream analog of BufferedInputStream. It also provides a replacement for the deprecated readLine() method of DataInputStream, which did not properly convert bytes into characters.

public class BufferedReader extends Reader {
    // Public Constructors
            public BufferedReader(Reader in, int sz);
            public BufferedReader(Reader in);
    // Public Instance Methods
            public void close() throws IOException;  // Defines Reader
            public void mark(int readAheadLimit) throws IOException;  // Overrides Reader
            public boolean markSupported();  // Overrides Reader
            public int read() throws IOException;  // Overrides Reader
            public int read(char[] cbuf, int off, int len) throws IOException;  // Defines Reader
            public String readLine() throws IOException;
            public boolean ready() throws IOException;  // Overrides Reader
            public void reset() throws IOException;  // Overrides Reader
            public long skip(long n) throws IOException;  // Overrides Reader
}
