Question: 1 / 510

What feature do BufferedReader and BufferedWriter provide?

Primitive data type handling

Automatic data conversion

Buffering for efficiency

The BufferedReader and BufferedWriter classes provide the ability to read and write data efficiently by buffering input and output operations. This allows for faster reading and writing of larger amounts of data. Option A is incorrect because BufferedReader and BufferedWriter do not handle primitive data types - that is the job of the DataInputStream and DataOutputStream classes. Option B is incorrect because while both classes can handle data conversion, this is not their primary purpose. Option D is incorrect because formatted output is the responsibility of the PrintWriter class. Overall, the main feature of BufferedReader and BufferedWriter is the use of buffering to improve efficiency when reading and writing data.
