适配器模式1

上代码：

Person类

package com.wjy.adaptable.entity;import com.wjy.adaptable.adaptabler.MainOperator;public class Person implements IAdaptable{   public String name;   public int age;public String getName() {    return name;}public void setName(String name) {    this.name = name;}public int getAge() {    return age;}public void setAge(int age) {    this.age = age;}@Overridepublic Object getAdapter(Class adapter) {    // TODO Auto-generated method stub    if(adapter==MainOperator.class)        return new MainOperator(this);    return null;}   }

person类的三个子类：

package com.wjy.adaptable.entity;import com.wjy.adaptable.adaptabler.AdultOperator;public class Man extends Person {public double height;public double weight;public double getHeight() {    return height;}public void setHeight(double height) {    this.height = height;}public double getWeight() {    return weight;}public void setWeight(double weight) {    this.weight = weight;}@Overridepublic Object getAdapter(Class adapter) {    // TODO Auto-generated method stub    if(adapter==AdultOperator.class)        return new AdultOperator(this);    return null;}}package com.wjy.adaptable.entity;import com.wjy.adaptable.adaptabler.AdultOperator;public class Woman extends Person {public double height;public double weight;public double getHeight() {    return height;}public void setHeight(double height) {    this.height = height;}public double getWeight() {    return weight;}public void setWeight(double weight) {    this.weight = weight;}@Overridepublic Object getAdapter(Class adapter) {    // TODO Auto-generated method stub    if(adapter==AdultOperator.class)        return new AdultOperator(this);    return null;}}package com.wjy.adaptable.entity;import com.wjy.adaptable.adaptabler.ChildOperator;import com.wjy.adaptable.adaptabler.MainOperator;public class Child extends Person {public double height;public double weight;public double getHeight() {    return height;}public void setHeight(double height) {    this.height = height;}public double getWeight() {    return weight;}public void setWeight(double weight) {    this.weight = weight;}@Overridepublic Object getAdapter(Class adapter) {    // TODO Auto-generated method stub    if(adapter==ChildOperator.class)        return new ChildOperator(this);    return null;}}

IAdaptable接口：

package com.wjy.adaptable.entity;public interface IAdaptable {    public abstract Object getAdapter(Class adapter);}

Result类：

package com.wjy.adaptable.entity;public class Result {   public int age;   public String name;   public double height;   public double weight;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 double getHeight() {    return height;}public void setHeight(double height) {    this.height = height;}public double getWeight() {    return weight;}public void setWeight(double weight) {    this.weight = weight;}   }

以下为为了实现适配器模式写的接口和类：

operateResult接口：

package com.wjy.adaptable.adaptabler;import com.wjy.adaptable.entity.Result;public interface operateResult {public abstract Result getPerson();}

MainOperator类：

package com.wjy.adaptable.adaptabler;import com.wjy.adaptable.entity.Person;import com.wjy.adaptable.entity.Result;public class MainOperator implements operateResult{    Person person;    public MainOperator(Person person)    {        this.person=person;    }    @Override    public Result getPerson() {        // TODO Auto-generated method stub        return null;    }    }

MainOperator类的两个子类，其中AdultOperator类处理Woman和Man：
ChildOperator类处理Child:

package com.wjy.adaptable.adaptabler;import com.wjy.adaptable.entity.Man;import com.wjy.adaptable.entity.Person;import com.wjy.adaptable.entity.Result;import com.wjy.adaptable.entity.Woman;public class AdultOperator extends MainOperator{    public AdultOperator(Person person) {        super(person);    }    @Override    public Result getPerson() {        Result result = new Result();        if(person instanceof Man)        {            result.name=person.name;            result.age=person.age;            result.height=((Man) person).height;            result.weight=((Man) person).weight;        }        else if(person instanceof Woman)        {            result.name=person.name;            result.age=person.age;            result.height=((Woman) person).height;            result.weight=((Woman) person).weight;        }        return result;    }}package com.wjy.adaptable.adaptabler;import com.wjy.adaptable.entity.Child;import com.wjy.adaptable.entity.Person;import com.wjy.adaptable.entity.Result;import com.wjy.adaptable.entity.Woman;public class ChildOperator extends MainOperator {    Result result=new Result();    public ChildOperator(Person person) {        super(person);        // TODO Auto-generated constructor stub    }    @Override    public Result getPerson() {        Child child=(Child)person;        result.name=child.name;        result.age=child.age;        result.weight=child.weight;        result.height=child.height;        return result;    }    }

Main方法调用：

package com.wjy.adaptable.operator;import java.util.ArrayList;import java.util.List;import com.wjy.adaptable.adaptabler.AdultOperator;import com.wjy.adaptable.adaptabler.ChildOperator;import com.wjy.adaptable.entity.Child;import com.wjy.adaptable.entity.Man;import com.wjy.adaptable.entity.Person;import com.wjy.adaptable.entity.Woman;public class humanManager {public static void main(String[] args){    List<Person> persons=new ArrayList<>();    Woman woman=new Woman();    woman.age=21;    woman.name="yhw";    woman.height=167.00;    woman.weight=50.00;    persons.add(woman);        Man man=new Man();    man.age=21;    man.name="wjy";    man.height=177.00;    man.weight=74.00;    persons.add(man);        Child child=new Child();    child.name="xiaobu";    child.age=2;    child.height=55.00;    child.weight=88;    persons.add(child);        for (Person person : persons) {        if(person instanceof Man || person instanceof Woman)        {            System.out.println((((AdultOperator)(person.getAdapter(AdultOperator.class))).getPerson()).name);        }        else if(person instanceof Child)        {            System.out.println((((ChildOperator)(person.getAdapter(ChildOperator.class))).getPerson()).name);        }    }}}
