Extracting class from a type parameter in Java

it’s simple. Observe the following example:


public class GenericClass<T> {

private Class<T> typeOfT;

@SuppressWarnings("unchecked")
public GenericClass() {
this.typeOfT = (Class<T>)
((ParameterizedType)getClass()
.getGenericSuperclass())
.getActualTypeArguments()[0];
}
