Mi a hiba ebben a java programban? Hibaüzenet a leírásban.

Bemásolom a LottoEvent programkódját:

import javax.swing.*;

import java.awt.event.*;

public class LottoEvent implements ItemListener, ActionListener,

Runnable {

LottoMadness gui;

Thread playing;

public LottoEvent(LottoMadness in) {

gui = in;

}

public void actionPerformed(ActionEvent event) {

String command = event.getActionCommand();

if (command == "Play") {

startPlaying();

}

if (command == "Stop") {

stopPlaying();

}

if (command == "Reset") {

clearAllFields();

}

}

void startPlaying() {

playing = new Thread(this);

playing.start();

gui.play.setEnabled(false);

gui.stop.setEnabled(true);

gui.reset.setEnabled(false);

gui.quickpick.setEnabled(false);

gui.personal.setEnabled(false);

}

void stopPlaying() {

gui.stop.setEnabled(true);

gui.play.setEnabled(false);

gui.reset.setEnabled(false);

gui.quickpick.setEnabled(false);

gui.personal.setEnabled(false);

playing = null;

}

void clearAllFields() {

for (int i = 0; i < 6; i++) {

gui.numbers[i].setText(null);

gui.winners[i].setText(null);

}

gui.got3.setText(null);

gui.got4.setText(null);

gui.got5.setText(null);

gui.got6.setText(null);

gui.drawings.setText(null);

gui.years.setText(null);

}

public void itemStateChanged(ItemEvent event) {

Object item = event.getItem();

if (item == gui.quickpick) {

for (int i = 0; i < 6; i++) {

int pick;

do {

pick = (int) Math.floor(Math.random() * 50 + 1);

} while (numberGone(pick, gui.numbers, i));

gui.numbers[i].setText("" + pick);

}

} else {

for (int i = 0; i < 6; i++) {

gui.numbers[i].setText(null);

}

}

}

void addOneToField(JTextField field) {

int num = Integer.parseInt("0" + field.getText());

num++;

field.setText("" + num);

}

boolean numberGone(int num, JTextField[] pastNums, int count) {

for (int i = 0; i < count; i++) {

if (Integer.parseInt(pastNums[i].getText()) == num) {

return true;

}

}

return false;

}

boolean matchedGone(JTextField win, JTextField[] allPicks) {

for (int i = 0; i < 6; i++) {

String winText = win.getText();

if ( winText.equals( allPicks[i].getText() ) ) {

return true;

}

}

return false;

}

public void run() {

Thread thisThread = Thread.currentThread();

while (playing == thisThread) {

addOneToField(gui.drawings);

int draw = Integer.parseInt(gui.drawings.getText());

float numYears = (float)draw / 104;

gui.years.setText("" + numYears);

int matches = 0;

for (int i = 0; i < 6; i++) {

int ball;

do {

ball = (int)Math.floor(Math.random() * 50 + 1);

} while (numberGone(ball, gui.winners, i));

gui.winners[i].setText("" +ball);

if ( matchedOne(gui.numbers, gui.winners[i]) ) {

matches++;

}

}

switch (matches) {

case 3:

addOneToField(gui.got3);

break;

case 4:

addOneToField(gui.got4);

break;

case 5:

addOneToField(gui.got5);

break;

case 6:

addOneToField(gui.got6);

gui.stop.setEnabled(false);

gui.play.setEnabled(true);

playing = null;

}

try {

Thread.sleep(100);

} catch (InterruptedException e) {

//semmit sem csinálunk

}

}

}

}

Nem jöttem rá, hogy mi a hiba úgyhogy ha valaki látja akkor kérem írja meg nekem.
