Java实现企业发放的奖金根据利润提成问题

import java .util.*;
public class test {
  public static void main (String[]args){
    double sum;//声明要储存的变量应发的奖金
    Scanner input =new Scanner (System.in);//导入扫描器
    System.out.print ("输入当月利润");
    double lirun=input .nextDouble();//从控制台录入利润
    if(lirun<=100000){
      sum=lirun*0.1;
    }else if (lirun<=200000){
      sum=10000+lirun*0.075;
    }else if (lirun<=400000){
      sum=17500+lirun*0.05;
    }else if (lirun<=600000){
      sum=lirun*0.03;
    }else if (lirun<=1000000){
      sum=lirun*0.015;
    } else{
      sum=lirun*0.01;
    }
    System.out.println("应发的奖金是"+sum);
    }
}
