What type of data do DataInputStream and DataOutputStream handle?

  1. Text data

  2. Primitive data types

  3. Serialized objects

  4. XML data

The correct answer is: Primitive data types

DataInputStream and DataOutputStream handle a variety of built-in data types such as integers, floating point numbers, booleans, and characters. Option A is incorrect because they do not specifically handle text data, but can convert it to the appropriate data type. Option C is incorrect because they handle raw data, not serialized objects. Option D is incorrect because they do not handle XML data specifically, but can be used to handle non-XML data as well.
