Hello,

The BufferedReader class is present in the java.io package:

java.io.BufferedReader

This class is used for reading the text-input stream in Java efficiently. This java.io.BufferedReader class buffers the characters which results in the high efficiency of the application.

The java.io.BufferedReader class can be used to read the large text files ( ranging in many GB's).

The java.io.BufferedReader class is very flexible and it allows the developers to specify the size of buffer. The default buffer size of this class is 8192 chars. Which can be increased also. This buffer size is sufficient in general programming.

You can see the example at the tutorial Java Read File Line by Line - Java Tutorial.

Thanks
