• This program performs the task of reading data from a given file by employing    BufferedInputStream() method.
• This method helps in speedy access of data, and reduces time consumption.
• First step of execution includes converting the contents of input file into bytes.
• This byte-stream is then stored in a FileInputStream type object.
• Those converted bytes are then transformed into an array of bytes.
• For this purpose, a new object of BufferedInputStream is instantiated, which takes that file object as an argument to its constructor.
• Initially, the first byte is read from the buffer, and is then stored into an integer variable.
• The while loop reads each line from the file using read() method, and continues doing so till the value of byte is not equal to -1.
• File is closed afterwards, also keep in mind, that file should be in the same location as the program.
