Answer 1

Employee类：

public class Employee {
    private String name;
    private int salary;
    private int subsidy;
    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;
    }
    
}

IncomeTax类：

import java.util.Scanner;

public class IncomeTax {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner sc = new Scanner(System.in);
        Employee emp = new Employee();
        System.out.print("请输入员工姓名：");
        String name = sc.next();
        emp.setName(name);
        System.out.print("请输入员工工资：");
        int gz = sc.nextInt();
        System.out.print("请输入员工加班补贴：");
        int bt = sc.nextInt();
        emp.setSalary(gz);
        emp.setSubsidy(bt);
        
        double shuijin = 0;
        int total = gz+bt-2000;
        if(total <=0)
            shuijin = 0;
        else if(total <= 500)
            shuijin = total * 0.05;
        else if (total <= 2000)
            shuijin = 500 * 0.05 + (total-500)*0.1;
        else if(total <= 5000)
            shuijin = 500 * 0.05 + 1500*0.1 + (total - 2000)*0.15;
        else if(total <=20000)
            shuijin =  500 * 0.05 + 1500*0.1 + 3000*0.15 + (total-5000)*0.2;
        else
            shuijin =  500 * 0.05 + 1500*0.1 + 3000*0.15 + 15000*0.2 + (total-20000)*0.3;
        
        System.out.println("税前收入："+(gz+bt)+",税后收入："+ (gz+bt-shuijin) + ",应纳所得税税额："+shuijin);
        
    }
