BufferedReader-BufferedWriter

BufferedReader and BufferedWriter are essential classes in Java for efficient reading and writing of text data. BufferedReader wraps around other Reader classes, allowing for buffered input, which minimizes I/O operations by reading characters in bulk rather than one at a time. This enhances performance, especially when dealing with large files. On the other hand, BufferedWriter serves a similar purpose for output, buffering characters before writing them to a file, which reduces the number of write operations. Together, these classes streamline file handling, making it easier to read from and write to text files in Java applications.
