如何获取列表的泛型类型，或者如果不可能解决所提供的任务？

public class MyList<T> extends ArrayList<T> {
    // ...
}

MyList<String> myList = new MyList<>();
Type genericType = myList.getClass().getGenericSuperclass();
if (genericType instanceof ParameterizedType) {
    ParameterizedType parameterizedType = (ParameterizedType) genericType;
    Type[] typeArguments = parameterizedType.getActualTypeArguments();
    if (typeArguments.length > 0) {
        Type typeArgument = typeArguments[0];
        System.out.println("泛型类型: " + typeArgument.getTypeName());
    }
}

public void processList(List<String> list) {
    Type genericType = getClass().getMethod("processList", List.class).getGenericParameterTypes()[0];
    if (genericType instanceof ParameterizedType) {
        ParameterizedType parameterizedType = (ParameterizedType) genericType;
        Type[] typeArguments = parameterizedType.getActualTypeArguments();
        if (typeArguments.length > 0) {
            Type typeArgument = typeArguments[0];
            System.out.println("泛型类型: " + typeArgument.getTypeName());
        }
    }
}
