What does ___sum ((int)a, (int) b)___do exactly? (line 5)

Question

public class Program{
public static void main (String []args){
double a = 3.14;
double b = 5.56;
sum((int)a,(int)b);}

static void sum (int a,int b) {
System .out .println (a+b);
}

}

Answer 1

the (int) convert double data type to integer data type......
so 3.14 and 5.56 get converted into 3 and 5 respectively...
then these integers i.e. 3 and 5 are used as parameters when calling the sum function.......

Answer 2

It will add those two perimeters together, sum(a, b) is the same like a+b

Answer 3

It calls the sum functions with the parameters (int)a (==3) and (int)b (==5)
