创建一个类的对象 [英] creating a object of class

问题描述

如何防止在没有其抽象类，静态类和私有构造函数的情况下创建类的对象.

how to prevent to creating a object of class without its make abstract class,static class,and private constructor.

推荐答案

我只能看到另一种方法要做到这一点，那就是一种病态的:以总是抛出异常的方式定义所有(非私有)构造函数.
我只想告诉这个问题，这是一个廉价的练习.它类似于一些想发明的毫无意义的面试问题之一.我认为，这与真实知识无关.我很乐意与无法正确回答这个问题，但能对事物有深刻思考和真正理解的人一起工作.

I can see just one more way to achieve that, a pathological one: define all (non-private) constructors the way they always throw an exception.

I just want to tell that this question is a cheap exercise. It resembles one of those pointless interview questions some like to invent. In my opinion, it has little to do with real knowledge. I would happily work with someone who would not be able to answer this question correctly but show some deep thinking and real understanding of things.
