package com.jerry.design.factoryMethod.imp;


/**

 * 

 * @author jerry

 *

 */

public interface interfaceTest {

public void test(String name);


}


实现类A：

package com.jerry.design.factoryMethod.impl;


import com.jerry.design.factoryMethod.imp.interfaceTest;



/**

 * 

 * @author jerry

 *

 */

public class ImplA implements interfaceTest {

public void test(String name){

System.out.println(" my ImplA name is："+name);

}


}

实现类B：

package com.jerry.design.factoryMethod.impl;


import com.jerry.design.factoryMethod.imp.interfaceTest;



/**

 * 

 * @author jerry

 *

 */

public class ImplB implements interfaceTest {

public void test(String name){

System.out.println(" my ImplB name is："+name);

}


}


抽象类：

package com.jerry.design.factoryMethod.imp;


public abstract class abstractClass {

public void test(String name){

interfaceTest impl = getImpl();

impl.test(name);

}


public  abstract interfaceTest getImpl() ;


}


子类A；

package com.jerry.design.factoryMethod.impl;


import com.jerry.design.factoryMethod.imp.abstractClass;


import com.jerry.design.factoryMethod.imp.interfaceTest;


public class ClassA extends abstractClass {


@Override

public interfaceTest getImpl() {

return new ImplA();

}


}


子类B：

package com.jerry.design.factoryMethod.impl;

import com.jerry.design.factoryMethod.imp.abstractClass;

import com.jerry.design.factoryMethod.imp.interfaceTest;

public class ClassB extends abstractClass {

@Override
public interfaceTest getImpl() {
return new ImplB();
}

}

测试类：

package com.jerry.design.factoryMethod.client;


import com.jerry.design.factoryMethod.imp.abstractClass;

import com.jerry.design.factoryMethod.impl.ClassA;

import com.jerry.design.factoryMethod.impl.ClassB;


public class Test{

public static void main(String[] args) {

abstractClass ac = new ClassA();

ac.test("yushh");

abstractClass ac2 = new ClassB();

ac2.test("yushh2");

// my ImplA name is：yushh

// my ImplB name is：yushh2

}

}


总结：分离出业务与创建，延迟实现。

package com.jerry.design.facade.imp;


public interface FacadeImp {

public void test();

public void testA();

public void testB();

public void testC();


}


实现类A：

package com.jerry.design.facade.impl;


import com.jerry.design.facade.imp.FacadeImp;



public class TestA implements FacadeImp {

public void test(){

System.out.println(" i am TestA's test()!");

}

public void testA() {

System.out.println(" i am TestA's testA()!");

}


@Override

public void testB() {

}


@Override

public void testC() {

}


}


实现类B：

package com.jerry.design.facade.impl;


import com.jerry.design.facade.imp.FacadeImp;



public class TestB implements FacadeImp {

public void test(){

System.out.println(" i am TestB's test()!");

}


@Override

public void testA() {

}


@Override

public void testB() {

System.out.println(" i am TestB's testB()!");

}


@Override

public void testC() {

}


}


实现类C：

package com.jerry.design.facade.impl;


import com.jerry.design.facade.imp.FacadeImp;



public class TestC implements FacadeImp {

public void testA() {

}


@Override

public void testB() {

}


@Override

public void testC() {

System.out.println(" i am TestC's testC()!");

}


}


外观类：

package com.jerry.design.facade.impl;


public class Facade {

public void testFacadeImplA(){

new TestA().test();

new TestB().test();

new TestC().test();

}

   public void testFacadeImplB(){

new TestA().testA();

new TestB().testB();

new TestC().testC();

}


}


调用代码：

package com.jerry.design.facade.client;


import com.jerry.design.facade.impl.Facade;


public class Test {


/**

* @param args

*/

public static void main(String[] args) {


new Facade().testFacadeImplA();

// i am TestA's test()!

// i am TestB's test()!

// i am TestC's test()!

new Facade().testFacadeImplB();

// i am TestA's testA()!

// i am TestB's testB()!

// i am TestC's testC()!

}


}

 

 


总结：使子系统易用

接口类：

package com.jerry.design.simpleFactory.imp;


/**

 * 

 * @author jerry

 *

 */

public interface interfaceTest {

public void test(String name);


}


实现类A：

package com.jerry.design.simpleFactory.impl;


import com.jerry.design.simpleFactory.imp.interfaceTest;


/**

 * 

 * @author jerry

 *

 */

public class ImplA implements interfaceTest {

public void test(String name){

System.out.println(" my ImplA name is："+name);

}


}


实现类B：

/**

 * 

 * @author jerry

 *

 */

public class ImplB implements interfaceTest {

public void test(String name){

System.out.println(" my ImplB name is："+name);

}


}


工厂类：

package com.jerry.design.simpleFactory.factory;


import com.jerry.design.simpleFactory.imp.interfaceTest;

import com.jerry.design.simpleFactory.impl.ImplA;

import com.jerry.design.simpleFactory.impl.ImplB;


public class Factory {

public static interfaceTest createImp(int type){

interfaceTest test = null;

if(type==1){

test  = (interfaceTest) new ImplA();

}else if(type==2){

test = (interfaceTest) new ImplB();

}

return test;

}


}


测试类：

package com.jerry.design.simpleFactory.factory;


import com.jerry.design.simpleFactory.imp.interfaceTest;


public class Test {


public static void main(String[] args) {

interfaceTest test = Factory.createImp(1);

test.test(" i am jerry!");// my ImplA name is： i am jerry!

test = Factory.createImp(2);

test.test(" i am jerry!");// my ImplB name is： i am jerry!

}

}



总结：简单工厂其实就是要选择实现的类而已。
