產品接口
package com.hg.demo.simplemode;
/**
* 泡麪接口
*/
public interface InstantNoodle {
/**
* 泡麪價格
* @return
*/
String noodlePrice();
/**
* 麪條口味
* @return
*/
String noodleFlavor();
/**
* 泡麪分量
* @return
*/
String noodleWeight();
}
產品實現1
package com.hg.demo.simplemode;
/**
* 康師傅面
*/
public class KangShiFuNoodle implements InstantNoodle{
@Override
public String noodlePrice() {
return "5.5元";
}
@Override
public String noodleFlavor() {
return "香辣味";
}
@Override
public String noodleWeight() {
return "220克";
}
}
產品實現2
package com.hg.demo.simplemode;
/**
* 老譚酸菜面
*/
public class LaoTanNoodle implements InstantNoodle{
@Override
public String noodlePrice() {
return "4.5元";
}
@Override
public String noodleFlavor() {
return "酸辣味";
}
@Override
public String noodleWeight() {
return "200克";
}
}
工廠靜態方法
package com.hg.demo.simplemode;
public class SimpleFactory {
public static final int TYPE_LT = 1;//老譚
public static final int TYPE_KSF = 2;//康師傅
public static InstantNoodle createNoodle(int type){
switch (type){
case TYPE_LT:
return new LaoTanNoodle();
case TYPE_KSF:
return new KangShiFuNoodle();
default:
return null;
}
}
}
客戶端調用工廠靜態方法生產產品
package com.hg.demo.simplemode;
public class Client {
public static void main(String[] args) {
InstantNoodle instantNoodle = SimpleFactory.createNoodle(SimpleFactory.TYPE_LT);
System.out.println("價格："+instantNoodle.noodlePrice());
System.out.println("口味："+instantNoodle.noodleFlavor());
System.out.println("分量："+instantNoodle.noodleWeight());
}
}

工廠接口實現
package com.hg.demo.methodmode;
public class NoodleFactory implements BaseFactory{
public static final String TYPE_LT = "LT";//老譚
public static final String TYPE_KSF = "KSF";//康師傅
@Override
public InstantNoodle createNoodle(String noodleType) {
if("LT".equals(noodleType)){
return new LaoTanNoodle();
}else if("KSF".equals(noodleType)){
return new KangShiFuNoodle();
}
return null;
}
}
客戶端
package com.hg.demo.methodmode;
public class Client {
public static void main(String[] args) {
BaseFactory factory = new NoodleFactory();
InstantNoodle noodle = factory.createNoodle("LT");
System.out.println("價格："+noodle.noodlePrice());
System.out.println("口味："+noodle.noodleFlavor());
System.out.println("分量："+noodle.noodleWeight());
}
}
總結：個人感覺工廠靜態模式和工廠方法模式只是工廠實現中一個是靜態方法創建產品實例，一個是接口方法創建產品實例，
兩種在增加新產品時，都需要修改工廠中的方法，兩種模式可能是用到的地方不同，可能我理解還不是很深
