BufferedReader-BufferedWriter

BufferedReader and BufferedWriter are essential classes in Java for efficient input and output operations. BufferedReader is designed to read text from character input streams, providing buffering to minimize the number of I/O operations, which enhances performance. It allows reading characters, arrays, and lines of text efficiently. On the other hand, BufferedWriter is used for writing text to character output streams, also utilizing buffering to optimize writing operations. Both classes are part of the java.io package and are commonly used for handling file operations, making them crucial for developers working with text data in Java applications.

Stream vs WriterReader API

Essential Java

Streams provide the most direct access to the binary content, so any InputStream / OutputStream implementations always operate on int s and byte s. // Read a single byte from the stream int b = inputS...

Pitfall - Small reads writes on unbuffered streams are inefficient

Essential Java

Consider the following code to copy one file to another: import java.io.*; public class FileCopy { public static void main(String[] args) throws Exception { try (InputStream is = new FileInputStream(a...

Reading a file using Channel and Buffer

Essential Java

Channel uses a Buffer to read/write data. A buffer is a fixed sized container where we can write a block of data at once. Channel is a quite faster than stream-based I/O. To read data from a file usin...
