Answer 1

Actually I tried several combinations but the (b-a )+a didnt work for me.
It always gives me 4000000000 is out of range. Without the 32768 also its that way.
int temp = (int)((((4000000000-1000000000)[phone]) *(Math.random() * 32768));Heres the entire loop.......size is the size of the foo Array I want to fill
          for (int i = 0; i < size; i++)
int temp = (int)((((4000000000-1000000000)[phone]) *(Math.random() * 32768)));
              //int temp = (int)Math.random()*32768;//Make random number same as c++
              if((temp < 1000000000)||(temp > 4000000000))
                   i--;
              else
                   foo[i] = temp;
                    System.out.println("Original Array: "+foo);
