    代码如下:

    
    public class 电话支付测试 {
    
    	public static void main(String[] args) {
    		MobilePhone mobile = new MobilePhone("15374363882", 80, 2, 30, 2);
    		Telephone tel = new Telephone("0797-8888888", 50, 2, 15);
    		mobile.pay();
    		mobile.display();
    		System.out.println("-------------------------------------------");
    		tel.pay();
    		tel.display();
    		
    	}
    }
    interface Payable{
    	void pay();
    }
    abstract class Phone{
    	String code;
    	public Phone(String code) {
    		this.code = code;
    	}
    	abstract void display();
    }
    class MobilePhone extends Phone implements Payable{
    	int time;
    	float price;
    	float internetFee;
    	float messageFee;
    	public MobilePhone(String code,int time,float price,float internetFee,float messageFee) {
    		super(code);
    		this.time = time;
    		this.price = price;
    		this.internetFee = internetFee;
    		this.messageFee = messageFee;
    	}
    	
    	@Override
    	void display() {
    		System.out.println("网费:¥"+ this.internetFee);
    		System.out.println("短信费:¥"+ this.messageFee);
    		System.out.println("通话费:¥"+ this.price*time);
    	}
    
    	@Override
    	public void pay() {
    		System.out.println("号码是:"+this.code +",本月费用合计:¥" + (price*time+internetFee+messageFee));
    		
    	}
    }
    class Telephone extends Phone implements Payable{
    	int time;
    	float price;
    	float monthFee;
    	public Telephone(String code,int time,float price,float monthFee) {
    		super(code);
    		this.time = time;
    		this.price = price;
    		this.monthFee = monthFee;
    	}
    	@Override
    	void display() {
    		System.out.println("¥月租费:"+ this.monthFee);
    		System.out.println("¥通话费:"+ this.price*time);
    	}
    	@Override
    	public void pay() {
    		System.out.println("号码是:"+this.code +",本月费用合计:¥" + (price*time+monthFee));
    	}
    }
    

    运行结果:
