Java で実行時にアノテーション値にアクセスするにはどうすればよいですか?

<code class="java">// Import the necessary classes
import java.lang.reflect.Field;
import java.lang.annotation.Annotation;

// Get the class object
Class<?> clazz = MyClass.class;

// Iterate over the fields of the class
for (Field field : clazz.getFields()) {

    // Check if the field has the Column annotation
    Annotation annotation = field.getAnnotation(Column.class);

    // If the annotation exists, read its columnName() value
    if (annotation != null) {
        String columnName = ((Column) annotation).columnName();
        System.out.println("Column Name: " + columnName);
    }
}</code>

<code class="java">for (Field field : clazz.getDeclaredFields()) {

    ...
}</code>
