answerWhich class in Java is used to read data line by line from a file?OptionsBufferedReaderFileWriterFileInputStreamOutputStream

The correct answer is BufferedReader.

Explanation:

• BufferedReader is a class in Java that is specifically designed to read text from an input stream, buffering characters for efficient reading of characters, arrays, and lines.
• It provides a method called readLine() which reads a line of text, making it suitable for reading data line by line from a file.

In contrast:

• FileWriter is used for writing character files and not for reading.
• FileInputStream is intended for reading binary data and doesn't provide line-by-line reading capabilities.
• OutputStream is a general class for writing byte streams and is not used for reading data.

Thus, if you want to read data line by line from a file, you would use BufferedReader.
