JAVA实现纳税算法

代码如下：

package com.kaifamiao.day1115;

import java.util.Scanner;

public class JiaoShui {
    private static double shui;
    private double salary;
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println("请输入你的年薪：");
        Double num = sc.nextDouble();
        double money = way(num);
        System.out.println("纳税金额："+money+"人民币");

    }
    public static double way(double salary){
        double sum=salary-60000;
        if (salary<=60000){
            shui=0;
        }
        if (sum<=36000){
            shui=sum*0.03;
        }
        if (sum>=36000 && sum<=144000 ){
            shui=sum*0.1-2520;
        }
        if (sum>=144000 && sum<=300000){
            shui=sum*0.2-16920;
        }
        if (sum>=300000 && sum<=420000){
            shui=sum*0.25-31920;
        }
        if (sum>=420000 && sum<=660000){
            shui=sum*0.3-52920;
        }
        if (sum>=660000 && sum<=960000){
            shui=sum*0.35-85920;
        }
        if (sum>=960000){
            shui=sum*0.45-181920;
        }
        return  shui;
    }
}
