Your sum variable should be casted into an integer... Try this:

double a=2.1;
double b=4;
double sum=a+b;
int sumInt=(int)sum;

you have to cast your variable to an integer: try it out like this:

System.out.println((int)(66.314));
System.out.println((int)(sum));

use a cast...

(int)double or else you can declare an int variable and assign that to double.You need to add cast as there is loss of precision

int value =(int)double_val

You can use the cast syntax. Note that this would raise a warning in most compilers/IDEs, as you are losing precision here:

int sum = (int)(a + b);
