When i use double it shows my number as 1.0E7?

Question

class Moqueet {
    public static void main(String [] args){
        double a, b, c;
        a = 1;
        b = 10000000;
        c = a * b;
        System.out.println(c);
    }
    }
    when i use double it shows output as 1.0E7

But when i use integer its 10000000.

Is there any way by which i can force double to show my number as 10000000.0 instead of 1.0E7

If you can't get used to the very sensible default format for a floating point double stringification, then use printf and supply an appropriate format specifier, %f is good for this case:

System.out.printf("%f\n", c);

\n is used for the newline.

I used System.out.printf("%f\n", c); but now output is 10000000.000000 is there any way to get rid of so many zero after decimal ? – Abdul.Moqueet Oct 18 '16 at 13:06
@Abdul.Moqueet `%.1f` to specify one decimal. – Andrew Li Oct 18 '16 at 13:08
Used %1f still the same :/ – Abdul.Moqueet Oct 18 '16 at 13:11
Did you forget the `.`? It is `%.1f`. – dudel Oct 18 '16 at 13:17
System.out.printf("%.1f\n", c); . Please use this one, and if the answer works do vote the comment :) – dildeepak Oct 18 '16 at 13:26
@dildeepak: would you answer comprehensively if we reopend the question? To me the duplicate is not quite right, this question seems to be more about "how can I format a double with a specific format". – Bathsheba Oct 18 '16 at 13:33
@Bathsheba, I understand the concern, but i just tried to provide the precise answer what developer was looking into. Thanks. – dildeepak Oct 19 '16 at 05:45
