How to generate random positive and negative numbers in Java

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

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

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

Generate numbers between 0 and 65535 then just subtract 32768
