What does the unary minus operator do in Java?

  1. Negates the operator

  2. Removes minus sign if present

  3. Doubles the value

  4. Converts to positive if negative

The correct answer is: Negates the operator

The unary minus operator in Java is used to negate a value, i.e., changing a positive value to a negative value or vice versa. This means that it performs the opposite operation of the given value. The other options, such as removing a minus sign if present or doubling the value, are not the expected behavior of the unary minus operator. Additionally, while the operator may convert a negative value to a positive value, its main purpose is to simply negate a value. Therefore, the best answer choice is A.
