Answer 2

Answer:

The correct answer is option 2) BufferedReader br=new BufferedReader(new FileReader ("a.txt"))

Explanation:

1. A Java class called BufferedReader reads text from the input stream. To read characters, arrays, etc. efficiently, it buffers the characters.
2. Since we can use the readline() function to read the data one line at a time, it inherits the reader class and makes the code efficient.
3. It enables the efficient reading of characters, arrays, and lines by buffering text as it is read from a character-input stream.
