通过DataOutputStream发送信息会引发异常

Question

考虑您在网络游戏中具有以下计时器的代码实现：

public void DefineTimer()
    {
            Action updateClockAction = new AbstractAction() {
                public void actionPerformed(ActionEvent e){

                    //System.out.println(javax.swing.SwingUtilities.isEventDispatchThread());

                     JPanelMainGame.this.jLabelSeconds.setFont(new java.awt.Font("Lucida Handwriting", 1, 36));
                     JPanelMainGame.this.jLabelSeconds.setForeground(Color.red);
                     JPanelMainGame.this.jLabelSeconds.setText(Integer.toString(JPanelMainGame.this.m_TimerTotalSeconds));

                    if( JPanelMainGame.this.m_TimerTotalSeconds >0)
                    {
                         JPanelMainGame.this.m_TimerTotalSeconds--;
                    }
                    else if ( JPanelMainGame.this.m_TimerTotalSeconds == 0)
                    {
                       // System.out.println(javax.swing.SwingUtilities.isEventDispatchThread());
                        JPanelMainGame.this.m_Timer.stop();
                        JPanelMainGame.this.jLabelSeconds.setText("0");
                        JPanelMainGame.this.jButtonFinish.setVisible(false);
                        System.out.println("after JbuttonFinish set visble false");
                        System.out.println("!m_WasGameDecisived: "+!m_WasGameDecisived);
                       // System.out.println(javax.swing.SwingUtilities.isEventDispatchThread());
                        JPanelGameApplet gameApplet = (JPanelGameApplet) getTopLevelAncestor();
                        //Checking whether time ended for both players and no solution was recieved

                        if(gameApplet.GetJPanelChooseGame().GetGameType() == eGameType.Net)
                        {

                            gameApplet.GetClinetThread().UpdateServerOfTimeEnded();
                            System.out.println("After Update");
                            if (!m_WasGameDecisived)
                            {
                                // System.out.println(javax.swing.SwingUtilities.isEventDispatchThread());
                                System.out.println("Tie - No one had a solution in the given time");


                                gameApplet.GetClinetThread().SendRequestToClosePlayerThreadAndRemoveItFromPlayersOnServer();
                                System.out.println("After SendRequestToClosePlayerThread");
                                gameApplet.GetClinetThread().CloseSocket();
                                System.out.println("After CloseSocket");
                                Menu.BrowseTo(PanelMenuNumber.k_ChooseGame, JPanelMainGame.this.getParent());
                                //askUserForAnotherRoundLeaveTableOrExitProgram();//////////////////////////////////////////////To implement
                            }
                        }
                        else if(gameApplet.GetJPanelChooseGame().GetGameType() == eGameType.Single)
                        {
                            JPanelMainGame.this.showPopUpSelectionBar();

                        }
                    }
                }
            };
            m_Timer = new Timer(1000, updateClockAction);
    }  

我添加了以下功能（它们写入相同的DataOutputStream：

gameApplet.GetClinetThread().UpdateServerOfTimeEnded();

gameApplet.GetClinetThread().SendRequestToClosePlayerThreadAndRemoveItFromPlayersOnServer();

添加它们之后，我会得到不一致的异常：有时，我在客户端中会遇到异常，因为其中一个功能或这两个功能或根本没有任何异常。
请帮我找出问题所在

根据您对问题的评论，“在Swing计时器内”表示存在设计缺陷，但异常本身只是网络错误，与Swing无关。 有一篇有关它的Microsoft知识库文章，您应该阅读，但简单来说， 带有此错误文本的此异常表示由于先前的网络发送问题，本地TCP堆栈已放弃对该连接的写入。
