Java.io.BufferedReader Class

Introduction

The Java.io.BufferedReader class reads text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines.Following are the important points about BufferedReader:

• The buffer size may be specified, or the default size may be used.
• Each read request made of a Reader causes a corresponding read request to be made of the underlying character or byte stream.

Class declaration

Following is the declaration for Java.io.BufferedReader class:

public class BufferedReader
   extends Reader

Field

Following are the fields for Java.io.BufferedReader class:

• protected Object lock -- This is the object used to synchronize operations on this stream.

6	String readLine() This method reads a line of text.
7	boolean ready() This method tells whether this stream is ready to be read.
8	void reset() This method resets the stream.
9	long skip(long n) This method skips characters.
