Declare double variables num$1,$ den$1,$ num$2,$ and den$2,$ and read each variable from input in that order. Find the sum of the fractions num$1/$den$1$ and num$2/$den$2$ and assign the result to fractionTotal.

The calculation is: sum num$1/$den$1+$ num$2/$den$2$ import java.util.Scanner;

public class SumCalculator $\{$

public static void main$($String$[]$ args$)\{$

Scanner scnr $=$ new Scanner$($System$.$in$)$;

double fractionTotal;

$/*$ Additional variable declarations go here $*/$

$/*$ Your code goes here $*/$

System.out.printf$("\%\mathrm{.}2$f$",$ fractionTotal$)$;
