员工类：

package day09;
    
    public abstract class Employee {
    	private String name;
        private int id;
        private int salary;
        
        public Employee(){}
        public Employee(String name,int id,int salary){
        	this.name=name;
        	this.id=id;
        	this.salary = salary;
        }
    	public String getName() {
    		return name;
    	}
    	public void setName(String name) {
    		this.name = name;
    	}
    	public int getId() {
    		return id;
    	}
    	public void setId(int id) {
    		this.id = id;
    	}
    	public int getSalary() {
    		return salary;
    	}
    	public void setSalary(int salary) {
    		this.salary = salary;
    	}
        public abstract void work();
    
    }

程序员类：

package day09;
    
    public class Programer extends Employee {
    
    	public Programer(){}
    	public Programer(String name,int id,int salary){
    		super(name,id,salary);
    	}
    	public void work() {
    		System.out.println("根据需求写代码！");
    
    	}
    
    }

经理类：

package day09;
    
    public class Manager extends Employee {
        private int bounds;//奖金
        
        public Manager(){}//无参构造
        public Manager(String name,int id,int salary,int bounds){//有参构造
        	super(name,id,salary);//传参
        	this.bounds=bounds;//传参
        }
    	public void work() {
    		System.out.println("和客户谈需求！！！");
    	}
    	public int getBounds() {
    		return bounds;
    	}
    	public void setBounds(int bounds) {
    		this.bounds = bounds;
    	}
        
    }

测试类：

package day09;
    
    
    public class EmployeeMain {
    
    
    	/**
    	 * @param args
    	 */
    	public static void main(String[] args) {
    		//多态实现
    		Employee emp = new Programer();
            emp.setName("李春男");
            emp.setId(10001);
            emp.setSalary(8000);
            System.out.println("姓名："+emp.getName()+"编号："+emp.getId()+"薪金"+emp.getSalary());
            emp.work();
            System.out.println("********************************");
            Employee emp1 = new Programer("李春男",10001,8000);
            emp.setSalary(8000);
            System.out.println("姓名："+emp.getName()+"编号："+emp.getId()+"薪金"+emp.getSalary());
            emp.work();
            
            //经理类
           /* emp = new Manager();
            emp.setName("杨莉");
            emp.setId(2001);
            emp.setSalary(6000);
            //emp.setBounds(1100);//编译看左边，emp是父类对象引用，而bounds是子类中特有的成变量，所以不能访问，报
    
    
    错！！
           */	
            //当遇到有子类特殊变量或者方法时，以上方式不可取，而是直接用具体的类创建对象
            
            Manager man = new Manager();
            man.setName("杨莉");
            man.setId(2001);
            man.setSalary(5000);
            man.setBounds(1200);
            System.out.println("姓名："+man.getName()+"编号："+man.getId()+"薪金"+man.getSalary());
            man.work();
            System.out.println("*********************************");
            Manager man1 = new Manager("杨莉",2001,5000,1200);
            System.out.println("姓名："+man1.getName()+"编号："+man1.getId()+"薪金"+man1.getSalary());
            man1.work();
    	}
    
    
    }

输出：

姓名：李春男编号：10001薪金8000  
根据需求写代码！
