新学的java有点问题求解答

一直学的c++这学期新开了个java学的不太懂今天讲了个父类子类更听不懂了，这个打了一节课也没整出来希望有懂得可以解答一下

父类Employee 按照一般定义的方法定义其属性和构造方法，及show方法即可。

子类Manager用extends关键字继承父类Employee，然后添加比父类新增的部门属性，及在构造方法用使用super关键字创建父类对象后，再给部门属性赋值即可，show()方法添加打印部门信息就可以了。代码如下：

public class Employee {
    
    public String name;
    public double salary;
    public String address;
    
    public Employee(String name, double salary, String address) {
        super();
        this.name = name;
        this.salary = salary;
        this.address = address;
    }
    
    
    public void show() {
        System.out.println("姓名："+this.name+",工资："+this.salary+",地址："+this.address);
    }
    
}

public class Manager extends Employee {

    public String department;
    
    public Manager(String name, double salary, String address,String department) {
        super(name, salary, address);
        this.department = department;
    }
    
    public void show() {
        System.out.println("姓名："+this.name+",工资："
                +this.salary+",地址："+this.address+",部门："+this.department);
    }
    

}



public class TestManager {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Manager m = new Manager("张三",8000, "成华大道","运输部");
        m.show();
    }

}

public class Employee {
    private String name;
    private String salary;
    private String address;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getSalary() {
        return salary;
    }

    public void setSalary(String salary) {
        this.salary = salary;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }
    public void Employee(String name,String salary,String address){
        this.name=name;
        this.salary=salary;
        this.address=address;
    }
    public void show(Employee employee){
        System.out.println("姓名:"+ name +"工资:"+ salary +"地址"+ address ) ;
    }
}

public class Manager extends Employee {
    private String department;

    public String getDepartment() {
        return department;
    }

    public void setDepartment(String department) {
        this.department = department;
    }

    @Override
    public void show(Employee employee) {
        System.out.println("姓名:"+ super.getName() +"工资:"+ super.getSalary() +"地址"+ super.getAddress()+"部门："+department ) ;
    }

    public static void main(String[] args) {
        Manager manager=new Manager();
        manager.setName("张三");
        manager.setSalary("3000");
        manager.setAddress("中国");
        manager.setDepartment("信息技术部");
        manager.show(manager);
    }
}

你好，这是java基础知识，直接贴代码反而不利于你的提升，你可以看看Java教材面向对象章节的继承与多态相关知识点，应该有助于你理解这道题
