How to convert xml into Java Object which contains ArrayList through XStream Library?

Question

I want to convert the XML file to Java object which have array. Objective is to store the xml values into the array of the object. Suppose XML file as:

<test>
     <Name> John</Nmae>
     <age>19</age>
     <phone>2225364</phone>
</test>

Now the Java Class is like:

public class TestArray
{
   private List list = new ArrayList();
   public display()
   {
        Iterator<String> itr = list.iterator();
        while(itr.hasNext())
        {
            System.out.println(itr.next());
         }
   }
 }

I want to parse the xml file to object so that I can retrieve the value of Name, Age and Phone from List. My approach is mention below,but it throws an error like

Exception in thread "main" com.thoughtworks.xstream.converters.ConversionException: Name : Name : Name : Name:

My Approach:

FileReader fr = new FileReader("test.xml"); 
XStream xstream = new XStream(new StaxDriver());        
xstream.alias("test", TestArray.class); 
xstream.addImplicitCollection(TestArray.class,"list");
TestArray ta = (TestArray) xstream.fromXML(fr);
ta.display();

Hmm ... I searched for [xstream tutorial](http://www.google.de/search?q=xstream+tutorial) and got a lot of them. Any problems with that? — Seelenvirtuose, Dec 18 '14 at 07:08

You need to create the list of object having the exact name as xml, so that it can map them. You need to have test class for each set of tags.

private List<Test> list = new ArrayList<Test>();

public class Test{

private String Name;

//other field and getter setters

}

what else you need friend – Panther Dec 18 '14 at 09:23
As you said I need create the list of object having the exact name as xml, You mean xml file which is Test.xml..I'm right?? and Where I need to declare the this Stmt: private List list = new ArrayList(); – Samraan Dec 18 '14 at 09:32
yes, as shown in my sammple code you will have list of Test type in your existing class , and you need this Test class having field name, age and phone. Hey could you use xml with tags starting with capital letters like Age and Phone. As in java, you will be having fields names starting with Capital letter. – Panther Dec 18 '14 at 09:43
