- The "(int)" parses the double to an int value replace 10 with
- your range of number.
- If you want a number between 5 and 15 the range is 10 [15-5]
- replace the 5 with the staring number.
- If you want the lowest number in the range to be 5 then add 5.
- Example :
- int ran = (int)(Math.random()*100)-50;
- will return a value in the range [-50;50]

- int random = (int)(Math.random()* 10 ) + 5;
- System.out.println(random);
