How to get attributes of annotations in Java using reflection?

I have several data classes in java of which I want to know - using reflection - which fields have a certain annotation with a certain attribute which is the following:

@Column(columnDefinition = "text") // Text with unbound length
private String comment;

I figured how to get the annotations of the field and whether it is of type Column:

private boolean isStringFieldWithBoundLength(Field attr) {
    Annotation[] annotations = attr.getDeclaredAnnotations();
    for (Annotation ann : annotations) {
        Class<? extends Annotation> aClass = ann.annotationType();
        if (Column.class == aClass) {
            
            // ...
            
        }
    }
}

Now in the debugger I can see that the aClass object has the information about the provided parameters. Unfortunately I don't know how to access it with code. Is it possible to access this information in java?
