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. -- Lew Waheed Rafiq wrote: > > 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 > Kristopher Micinsk wrote: > >> You seem to be quite confused...
