Accessing class variables from private actionPerformed method - methods

Question

In the code below, I don't know why the values of variables uNomba and list are NULL when accessed from jButton1ActionPerformed method. I would appreciate your help, on how I can successfully execute "new NewPlayer(uNomba, count, check, list).load();" such that all the values are passed to NewPlayer class. Thank you.
The first class - i.e The NewPlayer class
package mysound;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.util.ArrayList;
import java.util.Calendar;
import java.util.List;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class NewPlayer extends JPanel implements KeyListener, Runnable{
boolean isUpPressed, isDownPressed, isSpacePressed, isDone;
static JFrame f;
int spacebars=0;
boolean within;
public List spacebarLogMs = new ArrayList();
public List numSbar = new ArrayList();
Calendar cal = Calendar.getInstance();
LogResult logNow = new LogResult();
String directory;
String tabname; //table name used in the database connection
String bdir;
private int uNomba; //user number obtained from NewSound class
private String target;
private int incr;
private int userno;
private boolean moveon=true;
private List randlist;
private List numlist;
public void load() {
f = new JFrame();
f.setSize(600,300);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setContentPane(this);
f.setVisible(true);
setFocusable(true);
addKeyListener(this);
new Thread(this).start();
}
public NewPlayer() {
}
public NewPlayer(int UNOMBA, List NUMLIST){
this.uNomba = UNOMBA; //user number obtained from NewSound class
this.numlist=NUMLIST;
}
public NewPlayer(int USERNO, int INCR, boolean MOVEON, List NUMLIST){
this.userno=USERNO;
this.incr=INCR;
this.moveon=MOVEON;
this.numlist=NUMLIST;
}
public void keyTyped(KeyEvent ke) {
}
public void keyPressed(KeyEvent ke) {
switch(ke.getKeyCode()) {
case KeyEvent.VK_UP: isUpPressed = true; break;
case KeyEvent.VK_DOWN: isDownPressed = true; break;
case KeyEvent.VK_SPACE: isSpacePressed = true;
numSbar.add(System.currentTimeMillis());
System.out.println("That was a spacebar. "+spacebars++);
System.out.println("Current time: "+numSbar);
break;
}
}
public void keyReleased(KeyEvent ke) {
switch(ke.getKeyCode()) {
case KeyEvent.VK_UP: isUpPressed = false; break;
case KeyEvent.VK_DOWN: isDownPressed = false; break;
case KeyEvent.VK_SPACE: isSpacePressed = false; break;
}
}
public void closePrj(){
f.dispose();
}
public void run() { //introduce a target sound
String targetChoice;
int tIndex;
int i;
bdir="C:\\Users\\Abiodun\\Desktop\\testdata\\main\\zero\\atext\\"; //dir for text files
MainPlayer items = new MainPlayer (uNomba);
i=incr;
while(moveon){
System.out.println("Counter i: "+i+" Numlist: "+numlist);
if (i<numlist.size()){
int num = (int) numlist.get(i);
System.out.println("Num :"+num);
items.selectTarget(num);
items.selectChallenge(num);
items.playChallenge();
new WriteTime(bdir).tagTime(numSbar);
items.dataLogger();
moveon=false;
new Continue (uNomba, i, moveon, numlist).load();
}
}
}
}
The second class i.e the Continue class
public class Continue extends javax.swing.JDialog {
private int count;
private int usernumb;
private boolean check;
private int uNomba;
private String cdirectory;
private String cbdir;
private String ctabname;
private String ctarget;
private List list;
/**
* Creates new form Continue
*/
public Continue(java.awt.Frame parent, boolean modal) {
super(parent, modal);
initComponents();
}
public Continue(int CUNOMBA, int COUNT, boolean CHECK, List NLIST){
this.uNomba = CUNOMBA; //user number obtained from NewSound class
this.count=COUNT;
this.check=CHECK;
this.list=NLIST;
}
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
new NewPlayer().setVisible(false);//closePrj();
count++;
check=true;
new NewPlayer(uNomba, count, check, list).load();
System.out.println("Continue: UserNumber: "+uNumb+", Count: "+count+", Check: "+check+", nList"+lst);
this.setVisible(false);
}
Thanks sgroh. Here is what I just added: I created the following in
In NewPlayer class:
Continue ct = new Continue (new NewPlayer(uNomba, i, moveon, numlist));
In Continue Class,
private NewPlayer np;
public Continue (NewPlayer npy){
this.npy=np;
}
Just a recap, the main problem I am having is that I cannot access the values I passed from NewPlayer class from Continue class. I tested the values in side the following constructor in Continue class but not anywhere else in Continue class.
public Continue(int CUNOMBA, int COUNT, boolean CHECK, List NLIST){
this.uNomba = CUNOMBA; //user number obtained from NewSound class
this.count=COUNT;
this.check=CHECK;
this.nlist=NLIST;
System.out.println("Continue-constructor - uNomba: "+uNomba+", nList: "+list); //works fine! but not outside this constructor.
}

Answer 1

This code even compile, You haven't a constructor default (without fields).
this:
public Continue(java.awt.Frame parent, boolean modal) {
and This:
public Continue(int CUNOMBA, int COUNT, boolean CHECK, List NLIST){
this woun't compile:
Continue ctn = new Continue();

Answer 2

You have to create the Continue object using the right constructor or create the Default constructor.
You want also to print the variable uNumb in the System.out.println that doesn't exists.
