我有一個主類hello.java和一個Jframe welcome.java。 我想從hello.Java文件中調用Welcome.java文件。 Hello.java顯示一個Splashscreen，所以在顯示啓動畫面之後，我想讓我的Jframe顯示出來。我做了DIS在從另一個類調用Jframe
hello.java`
package splash;
import javax.swing.ImageIcon;
import javax.swing.JDialog;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.SwingUtilities;
/**
*
* @author Admin
*/
public class Splash {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
final JDialog frame = new JDialog(new JFrame());
frame.setSize(640, 360);
frame.setContentPane(new JLabel(new ImageIcon("C:\\Users\\Admin\\Desktop\\try5.gif")));
frame.setUndecorated(true);
frame.setResizable(false);
frame.setLocationRelativeTo(null);
frame.setDefaultCloseOperation(JDialog.DO_NOTHING_ON_CLOSE);
new Thread(new Runnable() {
@Override
public void run() {
sleepThread();
CloseDialog(frame);
// System.exit(0);
//編輯點評此行 }} ）開始（）;
ShowDialog(frame);
}
private static void sleepThread() {
try {
Thread.sleep(5000);
} catch (InterruptedException ex) {
// Do something, if there is a exception
System.out.println(ex.toString());
}
}
private static void ShowDialog(final JDialog dialog) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
dialog.setVisible(true);
}
});
}
private static void CloseDialog(final JDialog dialog) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
dialog.setVisible(false);
}
});
welcome wel = new welcome();
welcome.setNimbusFeel();
java.awt.EventQueue.invokeLater(new Runnable()
{
public void run(){
new welcome().setVisible(true);
}
}
);
}
}
和DIS在welcome.java
package splash;

/**

public class welcome extends javax.swing.JFrame {
final JDialog frame = new JDialog(new JFrame());
/**

public welcome() {
initComponents();
}

問題是什麼？ – Stefan
我需要調用Jframe從類dat顯示啓動屏幕 –
Thx fr的回覆。但只是刪除系統退出（0）frm主類和welcome.setvisible（true）在框架類給了一個完美的輸出。 –
