从接口参考中获取具体的类实现

Question

Is it possible in java to obtain ConcreetClass.class from interface reference ISomeInterface . I would like to avoid 'instance of' keyword.
On other words, is there:

ISomeInterface intRef = new ConcreetClass();
Class realization = intRef.getRealizationClass();
realization == ConcreetClass.class; // true 

If java doesn't support this operation. Could you recommend me a way to deal with it?

Answer 1

您应该能够使用getClass()方法获取任何对象的特定类。

Answer 2

getClass returns the class of the instance .

Class<? extends ISomeInterface> realization = intRef.getClass();
System.out.println(ConcreetClass.class.equals(realization)); //true
