BufferedReader is a buffered character input reader. Buffering allows reading from character streams more efficiently. If the default size of the buffer is not practical, another size may be specified. Reading a character from a Reader class usually involves reading a character from its Stream or subsequent Reader. It is advisable to wrap a BufferedReader around those Readers whose read operations may have high latency. For example, the following code

 BufferedReader inReader = new BufferedReader(new FileReader("file.java"));
 

will buffer input for the file file.java.
