Get Concrete Class name from Abstract Class

Question

在 Java 中，我可以在抽象类中获取扩展它的具体类的实例吗？

Answer 1

Yes, you can do this by calling this.getClass() . This will give you the Class instance for the runtime type of this .

If you just want the name of the class, you could use this.getClass().getName() .

Lastly, there are also this.getClass().getSimpleName() and this.getClass().getCanonicalName() . I use the former all the time to print readable class names to log files and the like.

Answer 2

Thread.currentThread().getStackTrace()[2].getClassName()
