What is the role of the @XmlElement annotation in JAXB?

B) To specify the root element of the XML document
C) To define the structure of the XML document
D) To define the type of XML elements
Answer:
A) To map a Java field to an XML element
Explanation:
The @XmlElement annotation in JAXB is used to map a Java field or property to an XML element. It is commonly used to specify how individual fields of a Java object should be represented in the corresponding XML document.
For example:
@XmlRootElement
public class User {
@XmlElement
private String name;
@XmlElement
private int age;
// Getters and setters
}
In this example, the name and age fields of the User class are mapped to XML elements.
