由于某种原因（看似完全独立于代码），我程序的框架只会出现一些（可能是20％）的时间。如果我只是连续点击运行，我最终会成功显示帧，但它永远不会重复。这有没有发生在其他人身上？我非常怀疑这与代码有关，但以防万一
public class Trader{
public static Trader INSTANCE = new Trader();
JTextArea msgBox;
ApiController m_controller;
Connection connect;
Quotes quotes;
ArrayList<String> m_acctList = new ArrayList();
public static void main(String[] args) {
INSTANCE.run();
}
public void run(){
connect = new Connection();
}
public ArrayList<String> accountList() { return m_acctList; }
public ApiController controller() { return m_controller; }
public JFrame frame() { return connect.frame; }
}
下一堂课
public class Connection implements IConnectionHandler{
static int port = 4001;
Quotes quotes;
JFrame frame;
CPanel panel;
boolean connected = false;
JTextArea logIn = new JTextArea();
JTextArea logOut = new JTextArea();
JTextArea msgBox = new JTextArea();
Logger loggerIn = new Logger(logIn);
Logger loggerOut = new Logger(logOut);
ApiController m_controller = new ApiController(this, loggerIn, loggerOut);
final ArrayList<String> m_acctList = new ArrayList<String>();
Connection(){
frame = new JFrame("Trader");
panel = new CPanel();
frame.add(panel);
frame.setSize(800,400);
frame.setResizable(false);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
class CPanel extends JComponent{
Point frameLoc = frame.getLocation();
Dimension frameSize = frame.getSize();
JLabel text = new JLabel("Messages");
JScrollPane messages = new JScrollPane(msgBox);
CPanel(){
setLayout(null);
add(text);
text.setBounds(frameLoc.x+5, frameLoc.y+5,
text.getPreferredSize().width, text.getPreferredSize().height);
add(messages);
msgBox.setEditable(false);
msgBox.setLineWrap(true);
messages.setBounds(text.getLocation().x, text.getLocation().y+text.getSize().height+10,
720, 300);
m_controller.connect(null, port, 0);
}
}
@Override public void connected() {
show( "connected");
m_controller.reqCurrentTime( new ApiController.ITimeHandler() {
@Override public void currentTime(long time) {
show( "Server date/time is " + Formats.fmtDate(time * 1000) );
}
});
m_controller.reqBulletins( true, new ApiController.IBulletinHandler() {
@Override public void bulletin(int msgId, Types.NewsType newsType, String message, String exchange) {

show( str);
show( message);
}
});
// Quotes quotes = new Quotes();
}
@Override public void disconnected() {
show( "disconnected");
}
@Override public void accountList(ArrayList<String> list) {
show( "Received account list");
m_acctList.clear();
m_acctList.addAll( list);
}
@Override public void error(Exception e) {
show( e.toString() );
}
@Override public void message(int id, int errorCode, String errorMsg) {

}
@Override public void show( final String str) {

msgBox.append( "\n\n");
Dimension d = msgBox.getSize();
msgBox.scrollRectToVisible( new Rectangle( 0, d.height, 1, 1) );
}
});
}
private static class Logger implements ILogger{
final private JTextArea msgBox;
Logger(JTextArea area){
msgBox = area;
}
@Override public void log(final String str) {
SwingUtilities.invokeLater( new Runnable() {
@Override public void run() {

// m_area.scrollRectToVisible( new Rectangle( 0, d.height, 1, 1) );
}
});
}
}
}
最后

}
}
catch(Exception ex){msgBox.append("Error getting quotes");}

for(int i = 0; i < numberOfStocks() -1 ; i++){
msgBox.append(stockList.get(i).m_description

}
}

}

}

}

}

return numberOfStocks;
}

}

}
public NewContract newContract(String symbol){

}
}
我非常怀疑代码与它有什么关系。我在IDE中遇到了一个问题。
