下面咱们继续第二种设计模式：简单工厂设计模式，相对于抽象工厂，这个设计模式应该相对比较简单点，所以大家不必觉得难懂！

 

Product 
public interface Work {

    void doWork();
}

ConcreteProduct 
public class StudentWork implements Work {

    public void doWork() {
        System.out.println("学生做作业!");
    }

}

public class TeacherWork implements Work {

    public void doWork() {
        System.out.println("老师审批作业!");
    }

}

Creator 
public interface IWorkFactory {

    Work getWork();
}

ConcreteCreator 
public class StudentWorkFactory implements IWorkFactory {

    public Work getWork() {
        return new StudentWork();
    }

}

public class TeacherWorkFactory implements IWorkFactory {

    public Work getWork() {
        return new TeacherWork();
    }

}

Test 
public class Test {

    public static void main(String[] args) {
        IWorkFactory studentWorkFactory = new StudentWorkFactory();
        studentWorkFactory.getWork().doWork();
        
        IWorkFactory teacherWorkFactory = new TeacherWorkFactory();
        teacherWorkFactory.getWork().doWork();
    }

}

result 
学生做作业!
老师审批作业!

 

 

 

看了这个设计模式，简单吧！

呵呵，有什么建议，多多留言！谢谢支持~
