What is the use of BufferedReader in Java programming?

Answer 1

The BufferedReader class provides buffering to your Reader's. Buffering can speed up IO quite a bit. Rather than read one character at a time from the network or disk, you read a larger block at a time. This is typically much faster, especially for disk access and larger data amounts.

The main difference between BufferedReader and BufferedInputStream is that Reader's work on characters (text), wheres InputStream's works on raw bytes.

To add buffering to your Reader's simply wrap them in a BufferedReader. Here is how that looks:

Reader input = new BufferedReader(

new FileReader("c:\\data\\input-file.txt"));

Answer 2

An InputStreamReader is a bridge from byte streams to character streams: It reads bytes and decodes them into characters using a specified charset. The charset that it uses may be specified by name or may be given explicitly, or the platform's default charset may be accepted.

Answer 4

is class for a java.lang.io package and DataInputStream used for a data input only.

any device you can input the data is very useful in java.

Answer 5

BufferedReader class is used to perform I/O operations in Java.
