All Implemented Interfaces:

Closeable, AutoCloseable, Readable

Direct Known Subclasses:

LineNumberReader
```
public class BufferedReader
extends Reader
```
Reads text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines.
The buffer size may be specified, or the default size may be used. The default is large enough for most purposes.
In general, each read request made of a Reader causes a corresponding read request to be made of the underlying character or byte stream. It is therefore advisable to wrap a BufferedReader around any Reader whose read() operations may be costly, such as FileReaders and InputStreamReaders. For example,
```
 BufferedReader in = new BufferedReader(new FileReader("foo.in"));
				 
```
will buffer the input from the specified file. Without buffering, each invocation of read() or readLine() could cause bytes to be read from the file, converted into characters, and then returned, which can be very inefficient.
Programs that use DataInputStreams for textual input can be localized by replacing each DataInputStream with an appropriate BufferedReader.

Constructor Summary

Constructors
Constructor	Description
`BufferedReader(Reader in)`	Creates a buffering character-input stream that uses a default-sized input buffer.
`BufferedReader(Reader in, int sz)`	Creates a buffering character-input stream that uses an input buffer of the specified size.

Method Summary

Modifier and Type	Method	Description
`Stream<String>`	`lines()`	Returns a `Stream`, the elements of which are lines read from this `BufferedReader`.
`void`	`mark(int readAheadLimit)`	Marks the present position in the stream.
`boolean`	`markSupported()`	Tells whether this stream supports the mark() operation, which it does.
`int`	`read()`	Reads a single character.
`int`	`read(char[] cbuf, int off, int len)`	Reads characters into a portion of an array.
`String`	`readLine()`	Reads a line of text.
`boolean`	`ready()`	Tells whether this stream is ready to be read.
`void`	`reset()`	Resets the stream to the most recent mark.
`long`	`skip(long n)`	Skips characters.
