Question

我正在尝试获取有关我正在创建的用于计算税款的JavaScript的帮助。感觉我的数学有问题，但是我认为代码按预期工作。当我输入2个值时，得出的数学值似乎并不准确。如果有人可以看一下，看看我的工作出了什么问题，那将不胜感激。

package taxableIncome;
import java.util.Scanner;

public class taxableIncome {
    public static void main(String[] args) {
        System.out.println("Enter filing status: ");
        Scanner input = new Scanner(System.in);
        double x = input.nextDouble();
        if (x == 0) {
            x = 'S';
        } else if (x == 1) {
            x = 'M';
        } else if (x == 2) {
            x = 'J';
        } else if (x == 3) {
            x = 'H';
            }

        System.out.println("Enter taxable income: ");
        input = new Scanner(System.in);
        double y = input.nextInt();

Answer 1

我更改输出以向用户提示他可以输入的内容。
因为要用它来确定状态，所以不必阅读两次更改即可存储第一个字符。
重命名了您的x和y，因为我不记得所有的x和y是什么意思。
从用户输入而不是int读取double。

public class taxableIncome {
  public static void main(String[] args) {
    System.out.println("Enter filing status (S,M,J,H): ");

    System.out.println("Enter taxable income: ");
    input = new Scanner(System.in);
    double taxableIncome = input.nextDouble();
    if (status == 'S') {
      if (taxableIncome <= 8350) {
