As Kristopher said, Java source is in "*.java" files and XML is in "*.xml" files. 

Also, Java follows Java syntax:

  package com.foo.bar;

  public class FooBar 

  {

    public static void main(String [] args)

    {

      // ... etc.

    }

  }

XML follows XML syntax:

  <rootTag>

    <someOtherTag someAttribute="value">

      <yetAnotherTag>content</yetAnotherTag>

      <moreTag id="more" value="barfoo" />

    </someOtherTag>

  </rootTag>

Now, when someone new to Java and XML runs into a question, it is good 

to search through the documentation for Java and for XML:

<http://docs.oracle.com/javase/>

<http://www.w3schools.com/xml/default.asp>

Read and study the tutorials, etc.

you defo got one thing right " I am confused" -:)  I actually thought I was writing code in java ?  so this now begs the question where do I write the code if not in MyFirstApp.main 

I am new to Java and XML

thanks for your prompt reply

You seem to be quite confused... You can't write an if statement
inside XML, it's not interactive (computation), it's just static XML.

What you need to do is put that in your java code,
