Java Please.

Declare double variables num1, den1, num2, and den2, and read each variable from input in that order. Find the difference of the fractions num1/den1 and num2/den2 and assign the result to diffFractions. The calculation is: Ex: If the input is 3.0 1.0 5.0 1.5, the output is: -0.33

Note: Assume that den1 and den2 will not be 0.

import java.util.Scanner;

public class DifferenceCalculator { public static void main(String[] args) { Scanner scnr = new Scanner(System.in);

double diffFractions;

//your code goes here

System.out.printf("%.2f", diffFractions);

}

}
