Question

I get the error above when doing the following
import oracle.xml.parser.v2.DOMParser;
public class testXML

I do not know how do you pass the JDK compiler.Typos in the transcription process. I was more interested in showing my approach rather than precise code (apologies).
Actual code below - less 2 methods I have not changed.

catch (Exception e)
