Java class object from type variable

Question

Is there a way to get Class object from the type variable in Java generic class? Something like that:

public class Bar extends Foo<T> {     public Class getParameterClass() {         return T.class; // doesn't compile     } } 

This type information is available at compile time and therefore should not be affected by type erasure, so, theoretically, there should be a way to accomplish this. Does it exist?

Answer 1

This works:

public static class Bar extends Foo<String> {   public Class<?> getParameterClass() {     return (Class<?>) (((ParameterizedType)Bar.class.getGenericSuperclass()).getActualTypeArguments()[0]);   } }
