Java-设计模式(Adapter适配器模式)-抽象类写法

package org.jzkangta.demo;

abstract class Person
{
	private String name;
	private int age;
	public int getAge() 
	{
		return age;
	}
	public void setAge(int age) 
	{
		this.age = age;
	}
	public String getName() 
	{
		return name;
	}
	public void setName(String name) 
	{
		this.name = name;
	}
	
	public Person(String name,int age)
	{
		this.setName(name);
		this.setAge(age);
	}
	
	public abstract String getSay();
	public void say()
	{
		System.out.println(this.getSay());
	}
}

class Worker extends Person
{
	private float money;

	public float getMoney() 
	{

	{

	}
}

class Student extends Person

public class Demo {

Java-设计模式(Adapter适配器模式)-接口写法

package org.jzkangta.demo02;

interface Eat
{
	public void eatBread();
	public void eatApple();
	public void eatBanana();
}

abstract class PersonEat implements Eat
{
	public void eatBread()
	{
		
	}
	public void eatApple(){}
	public void eatBanana(){}
}

class Person extends PersonEat
{
	public void eatBread()
	{
		System.out.println("我在吃面包");
	}
	
	public void eatApple()
	{
		System.out.println("我在吃苹果");
	}
}


public class Demo02 
{

	/**
	 * @param args
	 */
	public static void main(String[] args) 
	{
		Person p=new Person();
		p.eatBread();
		p.eatApple();

	}
