java编写的程序。求大神

import java.util.Scanner

public class IncomeTax {

public static double tax(Employee em) {

double tax=0

double per=0

double over=em.getSalary()+em.getSubsidy()-2000

if(over>20000){

per=0.3

}else if(over>5000){

per=0.2

}else if(over>2000){

per=0.15

}else if(over>500){

per=0.1

}else if(over>0){

per=0.05

}else{

per=0

}

tax=over*per

return tax

}

public static void main(String[] args) {

Employee em=new Employee()

Scanner input=new Scanner(System.in)

System.out.println("请输入员工的姓名：")

em.setName(input.nextLine())

System.out.println("请输入员工的工资返巧蔽："漏州)

em.setSalary(Double.parseDouble(input.nextLine()))

System.out.println("请输入员工加班补贴：")

em.setSubsidy(Double.parseDouble(input.nextLine()))

double tax=tax(em)

double before=em.getSalary()+em.getSubsidy()

double after=before-tax

System.out.println("员宽扒工"+em.getName()+"的税前收入为"+before+"元，税后收入为"+after+"元，您缴纳的个人所得税为"+tax+"元。")

}

}

public class Employee {

private String name

private double salary

private double subsidy

public String getName() {

return name

}

public void setName(String name) {

this.name=name

}

public double getSalary() {

return salary

}

public void setSalary(double salary) {

this.salary=salary

}

public double getSubsidy() {

return subsidy

}

public void setSubsidy(double subsidy) {

this.subsidy=subsidy

}

}

作用域的问题,修改如下:

import java.io.*

public class GongZi{

public static void main(String args[]){

String str=""

System.out.print("芦镇请首哗竖输入者大工资金额：")

try{

BufferedReader input=new BufferedReader(newInputStreamReader(System.in))

str=input.readLine()

}catch(IOException e){}

int qian=Integer.parseInt(str)

double shui = 0

if(qian<=1000){

shui=0

}else if(qian>1000&&qian<=1500){//100应改为1000

shui=(qian-1000)*0.05

}else if(qian>1500&&qian<=5000){

shui=(qian-1500)*0.2+25

}else if(qian>5000&&qian<=10000){

shui=(qian-5000)*0.3+725

}else{

shui=(qian-10000)*0.4+2225

}

System.out.println("您需要缴纳的税款为："+shui)

}

}
