What does the method getChars() do?

  1. Returns a new char array of the string characters

  2. Copies characters into a specified array

  3. Counts the characters in a string

  4. Changes the characters' case

The correct answer is: Copies characters into a specified array

The correct answer is B because the method getChars() is used to copy characters from a string into a specified array. This is different from option A, which creates a new array, and option C, which counts the characters without copying them. Option D is also incorrect because getChars() does not modify the case of the characters.
