**案例介绍**：![91b762a835814b678b633ceb5546e344.png][]

**创建父类：**

**创建子类继承抽象类：**

class Employees extends Person{//定义员工类，继承Person类
        public Employees(String name,String ID,double salary,int age)
        {
            super(name, ID, salary, age); //调用父类属性
        }
        public void add()//员工涨薪10%
        {
            double s=super.getSalary();
            super.setSalary(s*1.1);
        }
    }

class Manager extends Person{//定义经理类，继承Person类
        public Manager(String name,String ID,double salary,int age)
        {
            super(name, ID, salary, age); //调用父类属性
        }
        public void add()//经理涨薪20%
        {
            double s=super.getSalary();
            super.setSalary(s*1.2);
        }
    }

**定义测试类：**

public class test {
        public static void main(String[] args){
            Employees employees=new Employees("小王","001",5000,2);//创建Employees类的实例对象
            Manager manager=new Manager("小张","101",10000,5);//创建经理类的实例对象
            System.out.println("涨薪前：");
            System.out.println("员工"+employees.getName()+"的月薪是："+employees.getSalary());
            System.out.println("经理"+manager.getName()+"的月薪是："+manager.getSalary());
            employees.add();//调用Employees类的add()方法
            manager.add();//调用Manager类的add()方法
            System.out.println("涨薪后：");
            System.out.println("员工"+employees.getName()+"的月薪是："+employees.getSalary());
            System.out.println("经理"+manager.getName()+"的月薪是："+manager.getSalary());
        }
    }
