Get generic type of class at runtime

Question

How can I achieve this?

public class GenericClass<T>

{

    public Type getMyType()

    {

        //How do I return the type of T?

    }

}

Everything I have tried so far always returns the type Object rather than the specific type used.

Answer 1

Try this:

private Class<T> persistentClass;

public Constructor() {

    this.persistentClass = (Class<T>) ((ParameterizedType) getClass()

                            .getGenericSuperclass()).getActualTypeArguments()[0];

 }
