I still fail many of the tests.Could anyone explain me why?

Question

import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
Scanner sc=new Scanner(System.in);
String str=sc.nextLine();
String[]s1=str.split(",");
double g2=Integer.parseInt(s1[1]);
double g3=Integer.parseInt(s1[2]);
double co=g2+g3;
double res=((co)+co*0.07)*0.3;
System.out.println((int)Math.floor(res));
}
}

Answer 1

Can you post what the task is?
Why do you do the parsing instead of taking the input as the correct variable type?

Answer 2

// Change the index to 0,1 instead of 1,2

double g2=Integer.parseInt(s1[0]); // first index
double g3=Integer.parseInt(s1[1]); // second index

Answer 3

Killiam Chances ,

Hope this code helps

Scanner input = new Scanner(System.in);
String[] a = input.nextLine().split(",");

double[] lst = Arrays.stream(a).mapToDouble(num -> Double.parseDouble(num)).toArray();
Arrays.sort(lst);
lst = Arrays.copyOfRange(lst, 0, lst.length-1);

double t=0, tx=1.07, d=.3;
for (double x : lst) t += (x*tx)*d;
System.out.println((int)t);

Answer 4

Here is the task
Your favorite store is having a sale! You pay full price for the most expensive item that you get, but then you get 30% off of everything else in your purchase! How much are you going to save?
Sales tax is 7%.
Also, you leave anything below a dollar in your saving as a tip to the seller. If your saving is a round amount, you don't leave any tips.

Task:
Given the prices of items you want to purchase, determine how much you will save during your shopping!

Input Format:
An string of numbers separated by commas that represent the prices for all of the items that you want to purchase (without tax).

Output Format:
An integer number that represents the total savings that you got for shopping during the sale.

Sample Input:
100.25,80.99,40.00

Sample Output:
38
