Get class of generic

Question

My class starts with

public abstract class LastActionHero(){

Now somewhere in the code I want to write H.class<

Answer 1

We do it in the following way:

    private Class persistentClass;

    public Class getPersistentClass() {
        if (persistentClass == null) {
            this.persistentClass = (Class) ((ParameterizedType) getClass().getGenericSuperclass()).getActualTypeArguments()[0];
        }
        return persistentClass;
    }
