本文通过具体实例展示了Java中抽象类与继承的概念。定义了一个抽象类Staff，并创建了两个子类Manager和Member来实现抽象类的方法。Manager类用于表示管理者，包含职位和年薪属性；Member类用于表示普通成员，包含部门和月薪属性。最后通过实例化这两个类并调用print方法展示员工信息。

package xiti6;
abstract class Staff{
    String name;
    int age;
    String sex;
    abstract void print();
}
class Manager extends Staff{
    String post;
    int salary;
     Manager(String name,int age,String sex,String post,int salary){
        this.name=name;
        this.age=age;
        this.sex=sex;
        this.post=post;
        this.salary=salary;
    }
    void print(){
        System.out.println(this.name+","+this.age+","+this.sex+","+this.post+",年薪:"+this.salary);
    }
}
class Member extends Staff{
     Member(String name,int age,String sex,String department,int monpay){
        this.name=name;
        this.age=age;
        this.sex=sex;
        this.department=department;
        this.monpay=monpay;
    }
    String department;
    int monpay;
    void print(){
        System.out.println(this.name+","+this.age+","+this.sex+","+"属于"+this.department+",月薪:"+this.monpay);
    }
}
public class Fourth {
public static void main(String[] args) {
    Manager manager=new Manager("王二小",35,"男","CEO",2700000);
    manager.print();
    Member member=new Member("张小二",25,"男","生产管理部",8000);
    member.print();
}
}
