Answer:
It can take a negative input
Step-by-step explanation:
When you declare a variable in Java and you get your input via Scanner library; the Scanner library will accept the input irrespective of whether it's negative or not.
Take for instance, the following segment
Scanner input = new Scanner(System.in);
int userinput = input.nextInt()
Irrespective of whether userinput is negative or positive, it'll accept it.
