类图：

1 public interface IFactory {
2     public Operation createOperation();
3 }
1 public class AddOperationFactory implements IFactory {
2 
3     @Override
4     public Operation createOperation() {
5         return new AddOperation();
6     }
7 }
 1 public class Client {
 2 
 3     public static void main(String[] args)
 4     {
 5         IFactory addFactory = new AddOperationFactory();
 6         Operation add = addFactory.createOperation();
 7         add.setNumberA(1);
 8         add.setNumberB(2);
 9         System.out.println(add.getResult());
10     }
