Those who use it will find that they often have to write the same code each time they want to create a different Singleton class.

他们会发现每次他们要创建一个不同的单例类的时候，都不得不写同样得代码。

youdao

The only other method (set in italics) in the class is used to get a reference to the singleton and to create it if it is not yet instantiated.

该类中仅剩的另一个方法(用斜体标识)用于获取该单件的一个引用，如果尚未实例化则创建它。

youdao

Likewise, with a singleton implemented as single instance, you leave open the possibility of altering the class to create more instances in the future.

同时，如果使用创建单实例的方法实现单例模式，单例类还具有创建多个实例的变通能力。

So, it also can be used to create a singleton instance of a class.

因此，它也可以用来创建一个类的单身实例。
