1.基类

package com.test;
    
    public class Employee {
    	
    	String name;//name是名字
    	String address;//address是地址
    	double basic;//basic是基本底薪
    	
    	
    	public Employee(String name,double basic,String address) {
    		this.name=name;
    		this.basic=basic;
    		this.address=address;
    	}
    	
    	public String show() {		
    
    		return "姓名:"+"\t"+name+"\n"+
    				"地址:"+"\t"+address+"\n"+
    				"基本底薪:"+"\t"+basic+"\n"	;
    	}
    }

2.Director类

package com.test;
    
    public class Director  extends Employee {
    	
    	double transportAllowance;//津贴
    	
    	public Director(String name, double basic, String address,double transportAllowance) {
    		super(name, basic, address);//调用父类的构造方法
    		this.transportAllowance=transportAllowance;
    	}
    	//重写父类的show方法
    	public String show() {
    		return super.show()+"交通津贴:"+"\t"+transportAllowance;
    		
    	}
    
    	
    }

3.Manager类

package com.test;
    
    public class Manager extends Employee {
    	
    	String department;//部门
    	
    	public Manager(String name, double basic, String address ,String department ) {
    		super(name, basic, address);//调用父类的构造方法
    		this.department=department;
    	}
    	
    	//重写父类的show方法
    	public String show() {
    		return super.show()+"部门:"+"\t"+department;
    		
    	}
    
    	
    	
    }

4.EmployeeTest测试类

package com.test;
    
    public class EmployeeTest {
    
    	public static void main(String[] args) {
    		//创建子类对象并初始化
    		Employee mag =new Manager("Henry", 5500.65, "Sydney","会计师");
    		Employee dir =new Director("Stephen", 32564.0, "New York",8000.0);
    		//打印经理详细信息
    		System.out.println("经理详细信息");
    		System.out.println("===================");
    	    System.out.println(mag.show());
    	    //打印董事详细信息
    		System.out.println();
    		System.out.println("董事详细信息");
    		System.out.println("===================");
    		System.out.println(dir.show());
    	}
    
    }
