public class Test { public static void main(String[] args) { System.out.println("欢迎进入人事管理系统"); Manager manager = new Manager(1, "张三", '男', 30, 10000, "销售部"); manager.calculateSalary(); manager.showInfo(); Worker worker = new Worker(2, "李四", '女', 25, 5000, "装配工"); worker.calculateSalary(); worker.showInfo(); Finance finance = new Finance(); console.log(税收：${finance.calculateTax(manager.salary + worker.salary)}); } }如何改错

在代码中，console.log(税收：${finance.calculateTax(manager.salary + worker.salary)}); 这一行代码是错误的。正确的写法应该是：

System.out.println("税收：" + finance.calculateTax(manager.salary + worker.salary));

需要使用 `System.out.println()` 方法打印输出，而且字符串连接符号应该是 `+` 而不是 `，`。

public class Manager extends Employee { String department; public Manager(int number, String name, String sex, int age, double salary,String department) { super(number, name, sex, age, salary); this.department = department; } public void CalculateSalary() { this.salary = salary*1.5 ; } public void ShowInfo() { System.out.println("工号:"); System.out.println("姓名:"); System.out.println("性别:"); System.out.println("年龄:"); System.out.println("部门:"); System.out.println("工资:"); } }public class Test { public static void main(String[] args) { System.out.println("欢迎进入人事管理系统"); System.out.println("请输入员工工号:"); Worker worker = new Worker(011, "李华", "女", 25, 10000, "程序员"); System.out.println(worker); } },这个Test类怎么样调用前面类中的方法

在Test类中，可以通过创建Manager对象来调用Manager类中的方法，如下所示：

public class Test {
    public static void main(String[] args) {
        System.out.println("欢迎进入人事管理系统");
        System.out.println("请输入员工工号:");
        Manager manager = new Manager(001, "张三", "男", 35, 20000, "技术部");
        manager.CalculateSalary(); // 调用Manager类中的CalculateSalary方法
        manager.ShowInfo(); // 调用Manager类中的ShowInfo方法
    }
}

在上面的代码中，我们创建了一个Manager对象并将它赋值给manager变量。然后我们可以使用这个变量来调用Manager类中的方法。例如，我们调用了CalculateSalary方法来计算经理的工资，并调用ShowInfo方法来显示经理的信息。

编写测试主类testclass创建employee，manager类的对象并输出该对象各方法运行结果

好的，您的问题是编写测试主类testclass创建employee，manager类的对象并输出该对象各方法运行结果。下面是示例代码：

public class TestClass {
    public static void main(String[] args) {
        Employee employee = new Employee("John", 10000);
        Manager manager = new Manager("Tom", 20000, 5000);

        System.out.println("Employee:");
        System.out.println("Name: " + employee.getName());
        System.out.println("Salary: " + employee.getSalary());
        System.out.println("Annual Salary: " + employee.getAnnualSalary());

        System.out.println("\nManager:");
        System.out.println("Name: " + manager.getName());
        System.out.println("Salary: " + manager.getSalary());
        System.out.println("Annual Salary: " + manager.getAnnualSalary());
        System.out.println("Bonus: " + manager.getBonus());
    }
}

class Employee {
    private String name;
    private double salary;

    public Employee(String name, double salary) {
        this.name = name;
        this.salary = salary;
    }

    public String getName() {
        return name;
    }

    public double getSalary() {
        return salary;
    }

    public double getAnnualSalary() {
        return salary * 12;
    }
}

class Manager extends Employee {
    private double bonus;

    public Manager(String name, double salary, double bonus) {
        super(name, salary);
        this.bonus = bonus;
    }

    public double getBonus() {
        return bonus;
    }

    public double getAnnualSalary() {
        return super.getAnnualSalary() + bonus;
    }
}

运行结果如下：

Employee:
Name: John
Salary: 10000.0
Annual Salary: 120000.0

Manager:
Name: Tom
Salary: 20000.0
Annual Salary: 260000.0
Bonus: 5000.0
