What does the unary minus operator do in Java?

Negates the operator
Removes minus sign if present
Doubles the value
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.
