工厂模式

Posted 2020-10-12 kelly_one

还没有将工厂模式应用到实际的项目中去，今天学习了下，将其记录如下：

public class FactoryTest {
    public static void main(String[] args) {
        IWorkFactory i=new StudentWorkFactory();//接口的实现类由下面的接口的具体实现类实现
        i.getWork().work();//教师的工作  去工作的接口中用具体方法去实现

        IWorkFactory i1=new TeacherWorkFactory();
        i1.getWork().work();
    }}

interface IWorkFactory{
    Work getWork();
}
class StudentWorkFactory implements IWorkFactory{

    @Override
    public Work getWork() {
        return new StudentWork();
    }
}
class TeacherWorkFactory implements IWorkFactory{
    @Override
    public Work getWork() {
        return new TeacherWork();
    }
}
interface Work{
   void work();//接口中的方法默认为public abstract
                //接口中的变量默认为public static final

}
class StudentWork implements Work{
    public void work(){
        System.out.println("学生在读书");
    }
}
class TeacherWork implements Work{
    public void work(){
        System.out.println("老师批改作业");
    }
}
