Solution

A BufferedReader is a class that is used to read text from a character input stream efficiently. It provides buffering capabilities, which means it reads data from the input stream in chunks and stores it in memory. This allows for faster reading and improved performance.

On the other hand, a FileReader is a class that is used to read characters from a file. It reads data from the file character by character, without any buffering. This means that every read operation directly accesses the file, which can be slower compared to using a BufferedReader.

In summary, the main difference between a BufferedReader and a FileReader is that a BufferedReader provides buffering capabilities, while a FileReader does not. This buffering feature makes BufferedReader more efficient for reading large amounts of text from a file.
