        using Math class.

                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);
