案例介绍：

创建父类：

abstract class Person{//定义抽象公司人员类
    private String name;//姓名
    private String ID;//工号
    private double salary;//月薪
    private int age;//工龄
    public Person(String name,String ID,double salary,int age)
    {
        this.name=name;
        this.ID=ID;
        this.salary=salary;
        this.age=age;
    }

    public void setName(String name)
    {
        this.name = name;
    }
    public void setID(String ID)
    {
        this.ID = ID;
    }
    public void setSalary(double salary)
    {
        this.salary = salary;
    }
    public void setAge(int age)
    {
        this.age = age;
    }

    public String getName()
    {
        return name;
    }
    public String getID()
    {
        return ID;
    }
    public double getSalary()
    {
        return salary;
    }
    public int getAge()
    {
        return age;
    }

    abstract void add();//定义抽象涨薪方法
}

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());
    }
}

完整代码：

abstract class Person{//定义抽象公司人员类
    private String name;//姓名
    private String ID;//工号
    private double salary;//月薪
    private int age;//工龄
    public Person(String name,String ID,double salary,int age)
    {
        this.name=name;
        this.ID=ID;
        this.salary=salary;
        this.age=age;
    }

    public void setName(String name)
    {
        this.name = name;
    }
    public void setID(String ID)
    {
        this.ID = ID;
    }
    public void setSalary(double salary)
    {
        this.salary = salary;
    }
    public void setAge(int age)
    {
        this.age = age;
    }

    public String getName()
    {
        return name;
    }
    public String getID()
    {
        return ID;
    }
    public double getSalary()
    {
        return salary;
    }
    public int getAge()
    {
        return age;
    }

    abstract void add();//定义抽象涨薪方法

class Employees extends Person{//定义员工类，继承Person类
    public Employees(String name,String ID,double salary,int age)
    {

    public void add()//员工涨薪10%
    {
        double s=super.getSalary();
        super.setSalary(s*1.1);
    }

    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

        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
