Question

I have the following class

public class MyClass<T> {
    public Class<T> getDomainClass() {
          GET THE CLASS OF T
    }
}

I’ve googled this problem and all the answers I could find told me to use getGenericSuperClass(), but the problem of this method is that I must have a second class that extends MyClass and I don’t want to do this. What I need is to get the parametrized type of a concrete class?

Answer 1

You can’t. The information you want (i.e. the value of T) is not available at run-time due to type-erasure.
