How to generate random positive and negative numbers in Java [duplicate]

Question

I am trying to generate random integers over the range (-32768, 32767) of the primitive data type short. The java Random object only generates positive numbers. How would I go about randomly creating numbers on that interval? Thanks.

Answer 1

You random on (0, 32767+32768) then subtract by 32768

Answer 2

Random random=new Random();
int randomNumber=(random.nextInt(65536)-32768);

Answer 3

public static int generatRandomPositiveNegitiveValue(int max , int min) {
    //Random rand = new Random();
    int ii = -min + (int) (Math.random() * ((max - (-min)) + 1));
    return ii;
}
