work on removing and updating verse in java and DB

Seperate Props from Home.java into Props classes

Trying to pass int[] (generatedVerseCode static variable) from Home class to RefedVerses (extends Props abstract class) but getting NullPointerException thrown for the passed parameter.
This happens also when referring to generatedVerseCode as a static variable (Home.generatedVerseCode). Passing different variable results in the same issue. So I assume the problem is with the class structure listed below for RefedVerses.

`
package UI;

import java.util.Arrays;

import javax.swing.DefaultListModel;
import javax.swing.JFrame;
import javax.swing.JList;
import Study.Bible;
import Study.Verse;
import Utility.Log;

public abstract class Props {
JFrame frame;
JList list;
DefaultListModel model;
public Log p;

Props(JFrame frame, JList<String> list, DefaultListModel<String> model) {
	this(frame);
	this.list = list;
	this.model = model;
	this.list.setModel(this.model);
}

Props(JFrame frame) {
	this.frame = frame;
}

abstract void update(int[] verseData);
abstract JList<String> getListing(); 

}

class RefedVerses extends Props {

public RefedVerses(JFrame frame, JList<String> list, DefaultListModel<String> model) {
	super(frame,list,model);
}

// METHOD THROWING ERROR
@OverRide
public void update(int[] verseData) {
model.clear();
p.p("verseData: "+verseData[0]); //NullPointerException
Home.generateVerseCode[0]; //NullPointerException

}

private String verseBlock(int id) {
	int[] data = Bible.Book_Verses.getData(id);
	return Bible.Book_Verses.MAP.get(data[0])+" "+data[1]+": "+data[2];
}

@Override
public JList<String> getListing() {
	return list;
}

}

class Home implements Runnable {

Props refedVerses;

public void run() {
refedVerses = new RefedVerses(this, lstRef, model);

}
protected class LoadedVerses implements ListSelectionListener {
public void valueChanged(ListSelectionEvent arg0) {
refedVerses.update(generateVerseCode); //calling method
//generatedVerseCode is definitely not null here! *****************************
}
}
}
`

build architecture for having different translations for each verse. '

• modify database
  -edit Java code

generateVerseCode to match existing verses at addCommentary action event.
Using Book.findVerse(int[] verseCode)

have a JList showing updated references verses for the selected verse

Add error message for starting App with no db content loaded

alter db script to match new design. Change the <parent_verse> to <point_to> ARRAY (int)
