1、简单工厂模式
package com.jdwa.factory.simple;
public interface IProduct {
void use();
}
package com.jdwa.factory.simple;
public class Phone implements IProduct {
@Override
public void use() {
System.out.println("通话");
}
}
package com.jdwa.factory.simple;
public class Fridge implements IProduct {
@Override
public void use() {
System.out.println("保鲜食物");
}
}
package com.jdwa.factory.simple;
public class ProductFactory {
public IProduct create(Class<? extends IProduct> clazz){
if (clazz != null) {
try {
return clazz.newInstance();
} catch (Exception e) {
e.printStackTrace();
}
}
return null;
}
}
package com.jdwa.factory.simple;
public class Client {
public static void main(String[] args) {
ProductFactory factory = new ProductFactory();
IProduct fridge = factory.create(Fridge.class);
fridge.use();
}
}
2、工厂方法模式
package com.jdwa.factory.method;
public interface IProduct {
void use();
}
package com.jdwa.factory.method;
public class Fridge implements IProduct {
@Override
public void use() {
System.out.println("工厂方法-保鲜食物");
}
}
package com.jdwa.factory.method;
public class Phone implements IProduct {
@Override
public void use() {
System.out.println("工厂方法-通话");
}
}
package com.jdwa.factory.method;
public interface IProductFactory {
IProduct create();
}
package com.jdwa.factory.method;
public class FridgeFactory implements IProductFactory {
@Override
public IProduct create() {
return new Fridge();
}
}
package com.jdwa.factory.method;
public class PhoneFactory implements IProductFactory {
@Override
public IProduct create() {
return new Phone();
}
}
package com.jdwa.factory.method;
public class Client {
public static void main(String[] args) {
IProductFactory factory = new PhoneFactory();
IProduct ph = factory.create();
ph.use();
factory = new FridgeFactory();
IProduct fridge = factory.create();
fridge.use();
}
}
3、抽象工厂模式
package com.jdwa.factory.abstractfactory;
public interface IComputer {
void code();
}
package com.jdwa.factory.abstractfactory;
public interface IPhone {
void call();
}
package com.jdwa.factory.abstractfactory;
public class AppleComputer implements IComputer{
@Override
public void code() {
System.out.println("use apple computer to code ==");
}
}
package com.jdwa.factory.abstractfactory;
public class HuaWeiComputer implements IComputer {
@Override
public void code() {
System.out.println("use huawei computer to code===");
}
}
package com.jdwa.factory.abstractfactory;
public class ApplePhone implements IPhone {
@Override
public void call() {
System.out.println("use apple phone to call someone ===");
}
}
package com.jdwa.factory.abstractfactory;
public class HuaWeiPhone implements IPhone{
@Override
public void call() {
System.out.println("use huawei phone to call someone ===");
}
}
package com.jdwa.factory.abstractfactory;
public abstract class ProductFactory {
public void init(){
System.out.println("init============");
}
protected abstract IComputer createCom();
protected abstract IPhone createPh();
}
package com.jdwa.factory.abstractfactory;
public class AppleFactory extends ProductFactory {
@Override
protected IComputer createCom() {
return new AppleComputer();
}
@Override
protected IPhone createPh() {
return new ApplePhone();
}
}
package com.jdwa.factory.abstractfactory;
public class HuaWeiFactory extends ProductFactory {
@Override
protected IComputer createCom() {
return new HuaWeiComputer();
}
@Override
protected IPhone createPh() {
return new HuaWeiPhone();
}
}
package com.jdwa.factory.abstractfactory;
public class Client {
public static void main(String[] args) {
HuaWeiFactory huaWeiFactory = new HuaWeiFactory();
huaWeiFactory.createCom().code();
huaWeiFactory.createPh().call();
AppleFactory appleFactory = new AppleFactory();
appleFactory.createCom().code();
appleFactory.createPh().call();
}
}
