Get generic type of class at runtime

As others mentioned, it’s only possible via reflection in certain circumstances.

If you really need the type, this is the usual (type-safe) workaround pattern:

public class GenericClass<T> {

     private final Class<T> type;

     public GenericClass(Class<T> type) {
          this.type = type;

     public Class<T> getMyType() {
         return this.type;
