Java problem

Kako ti izgleda Menu_Main() klasa?

 

U biti nisi nista napravio, operator new se koristi ovako:

Rectangle rect = new Rectangle(origin, 100, 200);

 

Ovaj kod stvara novi objekt rect tipa Rectangle i konstruktoru predaje argumente origin, 100 i 200.

 

EDIT: I koristi stil Kod kad pises kod. Gore na toolbaru gdje ti pise Stilovi odaberes Kod i pocnes pisati. Shift + Enter je za novi red.

a kod u Menu_Main izgleda ovako:



package Game.Menu;

import java.awt.EventQueue;
import java.awt.Toolkit;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;

public class Menu_Main extends JFrame {

private static final long serialVersionUID = 1L;
private JPanel contentPane;

public Menu_Main() {
setResizable(false);
setTitle("My Game [Main Menu]");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(680, 480);
setLocationRelativeTo(null);
setIconImage(Toolkit.getDefaultToolkit().getImage("C:\\Icon.png"));
contentPane = new JPanel();
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
setContentPane(contentPane);
contentPane.setLayout(null);
JButton btnStartGame = new JButton("Start Game");
btnStartGame.setBounds(350, 30, 300, 50);
contentPane.add(btnStartGame);
JButton btnOptions = new JButton("Options");
btnOptions.setBounds(350, 110, 300, 50);
contentPane.add(btnOptions);
JButton btnCredits = new JButton("Credits");
btnCredits.setBounds(350, 190, 300, 50);
contentPane.add(btnCredits);
JButton btnQuitGame = new JButton("Quit Game");
btnQuitGame.setBounds(350, 270, 300, 50);
contentPane.add(btnQuitGame);
}

public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
Menu_Main frame = new Menu_Main();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
}

dobro, tnx... a sta da onda radim s kodom? samo ono:
Rectangle rect = new Rectangle(origin, 100, 200); ili?

fala, al ja jos ne kontam :D ja sam tek pocetnik... sad mi je ovakav kod, a opet ne radi:

 

package Game.Main;
import Game.Menu.Menu_Main;
public class Game {
private static final boolean running = true;
public static String title = "My Game";
public static int width = 680;
public static int height = 480;
Menu_Main menu = new Menu_Main();
public static void main(String[] args) {
if (running) {
Menu_Main menu;
System.out.println(title + " is running.");
} else {
System.out.println("Error trying to run the game.");
}
}
}

sta ja ocu je da izvrsi taj kod, i onda pokrene drugi class (Menu_Main) koji je Menu od igrice... kad odem na njega i kliknem Run sve radi, ali ocu kliknut Run na Game.class i onda da radi :/ neznam kak da bolje objasnim, evo ti kod od ta dva classa:

GLAVNI CLASS (Game.Main - Game)

package Game.Main;
import Game.Menu.Menu_Main;
public class Game {
private static final boolean running = true;
public static String title = "My Game";
public static int width = 680;
public static int height = 480;
Menu_Main menu = new Menu_Main();
public static void main(String[] args) {
Menu_Main menu;
if (running) {
System.out.println(title + " is running.");
} else {
System.out.println("Error trying to run the game.");
}
}
}

 

Ovo sta sam podcrto u kodu, tu mi daje upozorenje:

The value of the local variable menu is not used.

Eto ti procitaj pa mi reci sta ne radi... pls i fala, ja ne kontam, a di da iskoristim onaj "Menu_Main menu;" di imam upozorenje? :(

? koristim internet explorer ako si to mislio, a instaliro sam kolko ja znam 32 bit :)

nista te ne razumijem... ali ne koristim mozillu

Hvala vam svima na pomoci... ali skuzio sam sam :D

trebo sam stavit Menu_Main menu = new Menu_Main;

ko sto je 1domagoj1 reko :) ali jos ispod tog sam trebo:

menu.setVisible(true); nisam prije to imo pa zato nije

ni radilo... :D fala ljudi! :P

Da :D Al sad imam novi problem (mislim, nije nov, vec otprije).

:( Odem na:

1. Eclipse

2. Window

3. Preferences

4. Java

5. Code Style

6. Formatter

Napravim novi profil, na njemu sve namjesnim kak ocu, odaberem

taj profil, kliknem na Apply i onda na OK. Restartam Eclipse, i onda

se nista nije promjenilo! :O

Uvijek je dobro napisati kako si rijesio problem, mozda netko drugi naleti s istim problemom pa mu savjet moze pomoci. Tome forum i sluzi.

Ne, ovo je tema o programiranju u Javi, a ne o instalaciji Jave.

Jedna napomena: Budes li koristio apsolutno pozicioniranje komponenti (setBounds()) konstantno ces upadati u probleme. Nauci kako da koristis layout menadzere. Pozdrav.
