XML to Object mapping

Having hard time to map..
Calling rest and rest return response in XML format..
Help with class mapping in Java Object (method)
<aname>
<bname>
<c id="2">
<cname call="yes" text="no" email="yes"/>
<acc>
<accinfo name="ax" addr="USA"/>
</acc>
</c>
</bname>
</aname>
how can i convert above xml in Java class?
Thank You!

I share solution:
If you use need dependency
<!-- Jaxb -->
<dependency>
<groupId>javax.xml.bind</groupId>

"No suitable constructor found for type" and the type exists and has a default constructor

I am receiving this message in a new jersey 1.19.4 app that I am building:
No suitable constructor found for type [simple type, class javax.xml.bind.JAXBElement<com.objex.idms.idd.types.IDDModule>]: can not instantiate from JSON object (need to add/enable type information?)
at [Source: org.apache.catalina.connector.CoyoteInputStream#5a5e4ec1; line: 1, column: 2]
After much searching I have seen many posts that indicate this can be caused by a missing default constructor. However that doesn't seem to the the case here. Note I have tried this implementing "Serializable" with the same result. I am sure it's something simple but am just missing it.
Here is the class in question, any thoughts you might have would be appreciated.

I am using spring form tags to create registration form and added code as follows
<label>
<form:checkbox path="personalDetails.isPresentAddressSame" />
Present address same as above
</label>
As I have a variable personalDetails and it has a field isPresentAddressSame it should match the getter setter but I am getting following error
There was an unexpected error (type=Internal Server Error, status=500).
Invalid property 'personalDetails.isPresentAddressSame' of bean class [com.hr.foundation.models.doc.models.employee.Employee]: Bean property 'personalDetails.isPresentAddressSame' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?
Other fields with type String are matching with the path like personalDetails.firstName but not this Boolean field

You did not include the getter/setters of the PersonalDetails class, but Spring says that's where the error is.
Make sure you have these:
boolean isPresentAddressSame() { ... }
and
void setPresentAddressSame(boolean value) { ... }
Your mistake is likely that either:
You used a Boolean in either the parameter or return type (note the capital B)
You used getPresentAddressame which is only allowed for Boolean (note capital B again) instead of isPresentAddressSame which you should use for boolean (small B).
Clarification
Change:
public Boolean isPresentAddressSame() {
return isPresentAddressSame;
}
public void setPresentAddressSame(Boolean isPresentAddressSame) {
if (isPresentAddressSame) {
presentAddress = permanentAddress;
}
this.isPresentAddressSame = isPresentAddressSame;
}
to:
public boolean isPresentAddressSame() {
return isPresentAddressSame;
}
public void setPresentAddressSame(boolean isPresentAddressSame) {
if (isPresentAddressSame) {
presentAddress = permanentAddress;
}
this.isPresentAddressSame = isPresentAddressSame;
}
Note again that the boolean here uses a small b.

Try to change the signature of the method:
public Boolean isPresentAddressSame() {
return isPresentAddressSame;
}
to
public Boolean getPresentAddressSame() {
return isPresentAddressSame;
}
if you are using spring, spring alwais looking for get word to resolve the beans properties.

I have created model class using http://www.jsonschema2pojo.org/ below is my model class

This is the response from rest client

finally this is the way I am calling the api
GsonRequest request = new GsonRequest(Request.Method.GET, newConnectionAPI,null, ModelConnection.class, getHeaders(),
new Response.Listener<ModelConnection>() {
#Override
public void onResponse(ModelConnection response) {
if (listener != null) {
listener.networkResponseSuccessful(response);
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("volley error", "" + error);
}
});
request.setTag(tag);
request.setRetryPolicy(new DefaultRetryPolicy(15000, DefaultRetryPolicy.DEFAULT_MAX_RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
requestQueue.add(request);
when I debug I get all the values as null
Can anyone please help me out

Thought of answering my own question, may be someone can get help through this...
I created my Model class using jsonschema2pojo where I had to select JSON along with GSON(Which I forgot to select).
you can see the difference if you compare the Model classes posted above and below
public class ModelConnection {

May be because the objects were not properly serialized so GSON was unable to parse the JSON String properly.
Others advice over the above assumption is most welcome.

Java How create a set of object with two classes?

I have a logical problem to understand, how create a private set of inhabitant object. Here my two classes:
package main;
import java.util.Set;
/**
* #author
* #version 0.1
*
*/
public class City {
private String name;
/**
*HERE is my Problem*/
private Set<Inhabitants> Inhabitants {
}
/**
* standard cunstructor
*/
public City(String n, ) {
setName(n);
}
/**
* Search a particular name of inhabitant
* #return object of inhabitant
*/
static Set<Inhabitants> Search(){
return inhabitants;
}
/**
* Creates a inhabitant object and
* add to the set of inhabitants of the city
*
* #param name
* #param datebirth
* #param maritalStatus
* #
*/
public void Add(String name,String datebirth,String maritalStatus) {
}
/**
* Return all inhabitants objects of the city
* #return
*/
static Set<Inhabitants> ReturnAll(){
return inhabitants;
}
/**
* Return city name
* #return
*/
static Set<Inhabitants> ReturnCityName(){
return inhabitants;
}
/**
* #return the name
*/
public String getName() {
return name;
}
/**
* #param name the name to set
*/
public void setName(String name) {
this.name = name;
}
/**
* #return the inhabitants
*/
public Set<Inhabitants> getInhabitants() {
return inhabitants;
}
/**
* #param inhabitants the inhabitants to set
*/
public void setInhabitants(Set<Inhabitants> inhabitants) {
this.inhabitants = inhabitants;
}
}
package main;
/**
* #version 0.1
*/
public class Inhabitants {
private String name;
private String datebirth;
private Boolean maritalStatus;
/**
* standard constructor
*/
public Inhabitants() {
}
/**
* #return the name
*/
public String getName() {
return name;
}
/**
* #param name the name to set
*/
public void setName(String name) {
this.name = name;
}
/**
* #return the datebirth
*/
public String getDatebirth() {
return datebirth;
}
/**
* #param datebirth the datebirth to set
*/
public void setDatebirth(String datebirth) {
this.datebirth = datebirth;
}
/**
* #return the maritalStatus
*/
public Boolean getMaritalStatus() {
return maritalStatus;
}
/**
* #param maritalStatus the maritalStatus to set
*/
public void setMaritalStatus(Boolean maritalStatus) {
this.maritalStatus = maritalStatus;
}
}

It sounds like a simple problem. You didn't need so much code:

public class Person {
private final String name;
public Person(String name) {
if (name == null || name.trim().length() == 0) throw new IllegalArgumentException("name cannot be blank or null");
this.name = name;
}
public String getName() {
return name;
}
#Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
Person person = (Person) o;
return name.equals(person.name);
}
#Override
public int hashCode() {
return name.hashCode();
}
#Override
public String toString() {
final StringBuilder sb = new StringBuilder("Person{");
sb.append("name='").append(name).append('\'');
