新学的java有点问题求解答

Question

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

Answer 1

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();
    }

}
