Which class provides methods to encode and decode character data?

  1. CharSet

  2. CharBuffer

  3. Encoder

  4. Charset

The correct answer is: Charset

Charset is the correct answer as it is a class that provides methods specifically for encoding and decoding character data. The other options are incorrect because - A: CharSet is misspelled and is not a built-in class in Java. - B: CharBuffer is used for manipulating strings and character data, but does not have methods for encoding and decoding. - C: Encoder is an interface, not a class, and is used for transforming data, not specifically character data.
