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() 
	{
		return money;
	}

	public void setMoney(float money) 
	{
		this.money = money;
	}
	public Worker(String name,int age,float money)
	{
		super(name,age);
		this.setMoney(money);
	}
	
	public String getSay()
	{
		return "我是一个工人，我的名字是："+super.getName()+",年龄："+super.getAge()+",工资："+this.getMoney();
	}
}

class Student extends Person
{
	private float score;

	public float getScore() 
	{
		return score;
	}

	public void setScore(float score) 
	{
		this.score = score;
	}
	
	public Student(String name,int age,float score)
	{
		super(name,age);
		this.setScore(score);
	}
	
	public String getSay()
	{
		return "我是一个学生，我的名字是："+super.getName()+",年龄："+super.getAge()+",成绩："+this.getScore();
	}
}
public class Demo {

	/**
	 * @param args
	 */
	public static void main(String[] args) 
	{
		//Person p=new Worker("zhangsan",12,3000);
		Person p=new Student("lisi",18,90);
		p.say();

	}

}

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();

	}

}
