本文介绍了一个简单的工厂模式实现示例，展示了如何通过工厂类创建不同的服务实现类。具体包括两个服务实现类：Implementation1和Implementation2，每个类都实现了Service接口，并通过静态内部类的方式定义了各自的工厂。

interface Service
{
void method1();
void method2();
}
interface ServiceFactory
{
Service getService();
}
class Implementation1 implements Service
{
private Implementation1()
{

}
public void method1()
{
  System.out.println("Impelmentation1 method1()");
}
public void method2()
{
  System.out.println("Impelmentation1 method2()");
}
public static ServiceFactory factory = new ServiceFactory(){
  public Service getService()
  {
   return new Implementation1();
  }
};
}
class Implementation2 implements Service
{
private Implementation2()
{

}
public void method1()
{
  System.out.println("Impelmentation2 method1()");
}
public void method2()
{
  System.out.println("Impelmentation2 method2()");
}
public static ServiceFactory factory = new ServiceFactory(){
  public Service getService()
  {
   return new Implementation2();
  }
};
}
public class Factories
{
public static void ServiceConsumer(ServiceFactory fact)
{
  Service s = fact.getService();
  s.method1();
  s.method2();
}
public static void main(String args[])
{
  ServiceConsumer(Implementation1.factory);
  ServiceConsumer(Implementation2.factory);
}
}
