What will be the output of following program?
interface two {
int a = 10;
void root();
}
interface three extends two {
int b = 30;
void multiplication();
}
class Multiplication implements three {
public void root() {
System.out.println(Math.rint(Math.sqrt(a)));
}
public void multiplication() {
System.out.println(a * b);
}
}
public class Calculation {
public static void main(String args[]) {
Multiplication m = new Multiplication();
m.root();
m.multiplication();
}
}
