//To get a random number between a set range with min and max:

int number = random.nextInt(max - min) + min;
//It also works with negative numbers.

//So:

random.nextInt(30 + 10) - 10;
// max = 30; min = -10;
//Will yield a random int between -10 and 30 (exclusive).

//It also works with doubles.

/*
 * You can't use the Random class's nextInt(int bound) method to generate negative
 * numbers exclusively, since the method will throw an exception if it's negative.
 * So the @Witty Warbler's example may throw an exception. For example:
 * 
 * int min = Integer.MIN_VALUE;
 * int max = 0;
 * int error = new Random().nextInt(max - min) + min;
 * 
 * To get a random negative number, do the following:
*/

// Get a random number between Integer.MIN_VALUE and -1 inclusive
int randomNegNum = new Random().nextInt(Integer.MAX_VALUE) - Integer.MIN_VALUE;
