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.
