Xml Attribute to Pojo class in Java

 To convert the given XML to a Java POJO class using JAXB, you need to create the `Address` class representing the `<Address>` element and its attributes.

Here's how you can do it:

1. Create the `Address` class for the `<Address>` element:

import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "Address")
public class Address {
    private String street;
    private String city;
    private String zipcode;

    @XmlAttribute
    public String getStreet() {
        return street;
    }

    public void setStreet(String street) {
        this.street = street;
    }

    @XmlAttribute
    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    @XmlAttribute
    public String getZipcode() {
        return zipcode;
    }

    public void setZipcode(String zipcode) {
        this.zipcode = zipcode;
    }
}

2. Now, you can unmarshal the XML into the `Address` object:

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Unmarshaller;
import java.io.StringReader;

public class XmlToPojoMapper {

    public static void main(String[] args) {
        String xmlData = "<Address street=\"adr1\" city=\"cty1\" zipcode=\"01\"></Address>";

        try {
            // Create JAXBContext and Unmarshaller
            JAXBContext jaxbContext = JAXBContext.newInstance(Address.class);
            Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();

            // Unmarshal the XML data into Java object
            Address addressObject = (Address) unmarshaller.unmarshal(new StringReader(xmlData));

            // Now you can work with the Java object
            System.out.println("Street: " + addressObject.getStreet());
            System.out.println("City: " + addressObject.getCity());
            System.out.println("Zipcode: " + addressObject.getZipcode());
        } catch (JAXBException e) {
            e.printStackTrace();
        }
    }
}

When you run the `XmlToPojoMapper` class, it will unmarshal the XML data and populate the `Address` object with the corresponding attribute values. The output will be:

```

Street: adr1

City: cty1

Zipcode: 01

```

With this setup, you have successfully converted the given XML into a POJO class using JAXB. Make sure the XML data is well-formed and has the correct structure for proper unmarshalling.
