1>打开记事本，写如下一段代码：

public class Employee {
    
        private String name = ""; // 雇员名称
        private int salary = 0; // 雇员工资
        private int subsidy = 0; // 加班补贴
    
    
        public String getName() {
            return name;
        }
    
        public void setName(String name) {
            this.name = name;
        }
    
        public int getSalary() {
            return salary;
        }
    
        public void setSalary(int salary) {
            this.salary = salary;
        }
    
        public int getSubsidy() {
            return subsidy;
        }
    
        public void setSubsidy(int subsidy) {
            this.subsidy = subsidy;
        }
    
        public void calc() {
            float income = salary + subsidy; // 总收入为工资和加班补贴之和
            float tax = 0;
            float rate = 0; // 税率
            float afterTax = 0; // 税后工资
            if (income < 2000) { // 总收入为2000元以下，则免征税
                rate = 0;
            } else if (income >= 2000 && income < 2500) {
                rate = 0.05F;
            } else if (income >= 2500 && income < 4000) {
                rate = 0.1F;
            } else if (income >= 4000 && income < 7000) {
                rate = 0.15F;
            } else if (income >= 7000 && income < 22000) {
                rate = 0.2F;
            }else if(income >=22000){
                rate = 0.3F;
            }
            tax = income * rate; // 计算税收
            afterTax = income - tax; // 计算税后工资
            System.out.println("员工" + name + "的税前收入为" + income + "元,税后收入为"
            + afterTax + "元，您缴纳的个人所得税为" + tax + "元。");
        }
    }

保存为Employee.java【同上节，我还是把他放在了D盘下InputTest文件夹内】  
2>打开记事本，写如下一段代码：

import java.util.Scanner;
    public class IncomeTax{
        public static void main(String[] args){
            Scanner input = new Scanner(System.in);
            System.out.print("请输入员工的姓名：");
            String name = input.next();
            System.out.print("请输入员工工资：");
            int salary = input.nextInt();
            System.out.print("请输入员工加班补贴：");
            int subsidy = input.nextInt();
            Employee employee = new Employee();
            employee.setName(name); //员工名
            employee.setSalary(salary); //工资
            employee.setSubsidy(subsidy); //补贴
            employee.calc(); //计算个人所得税
        }
    }

保存为 IncomeTax.java【同上节，我还是把他放在了D盘下InputTest文件夹内】

打开dos运行窗口，输入d：转到D盘，接下来输入cd InputTest转到InputTest目录下：  
输入Javac IncomeTax.java 回车 java IncomeTax。

我们输入张三，8000,500 ；结果如下图：
