Answer 3

public class rounding {
public static void main(String[ ] args) {
double a = 12.765;
int b = (int) Math.round(a);
System.out.println(b);
}}

This is the Syntax used to round a double into an Integer , then printing the rounded value on the screen ; Actually in this piece of code we ae casting the Double value into an Integer by using Math class to round it .
