Java.io.BufferedReader Class in Java 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 java.io.BufferedReader.readline() method read a line of text.

The "BufferedWriter" class of java supports writing a chain of characters output stream (Text based) in an efficient way. The Chain-Of-Characters can be Arrays, Strings etc. The "BufferedReader" class is used to read stream of text from a character based input stream. Snarky answer: what you're doing wrong is only creating 2 objects in Java to do something if you search, you can probably find a few more classes that extend BufferedReader or ExtendedBufferReader etc., and then it can be real Enterprise Java. Now that i've gotten that out of my system: more useful answer. In this example, we will use BufferedReader Class to read file named "sample.txt". BufferedReader class is used to read the text from a character-based input stream. It can be used to read data line by line by readLine() method. It makes the performance fast.
