JavaSwing:JTabed用于将新组件放入选项卡

我正在开发Swing应用程序。我为新的日志进程创建了新选项卡。打印其中的所有控制台语句。当我在tab组件中放置tab时，它会得到不匹配的pro1 hold log2 pro2 hold log1，所以我挖掘了很多，但并没有弄清楚代码是如何遵循的

调用CreateNew选项卡方法的ProjectExecute事件

if (e.getSource() == btnExecute) {
            createTab();
            String s = new StringBuffer().append(ProjectOutPath).toString();
            dirr = new File(s);
            if (!dirr.exists()) {
            }
            final File tagFile = new File(dirr, projectName + ".log");

            if (!tagFile.exists()) {
                try {
                    tagFile.createNewFile();
                } catch (IOException e1) {
                    e1.printStackTrace();
                }
            }
            SwingWorker<Boolean, Integer> worker = new SwingWorker<Boolean, Integer>() {
                @SuppressWarnings({ "unchecked", "null" })
                @Override
                protected Boolean doInBackground() throws Exception {
                    PrintStream printStream = new PrintStream(new CustomOutputStream(logTextArea, tempArea));
                    System.setOut(printStream);
                    System.setErr(printStream);
                    File outFile = new File(tagFile.getAbsolutePath());
                    FileOutputStream outFileStream = new FileOutputStream(outFile);
                    PrintWriter outStream = new PrintWriter(outFileStream);
                    try {
                        System.out.println("ChooserFile 1 :" + chooserFile1);

                        MainApp.runApp(chooserFile1);

                        outStream.write(logTextArea.getText());
                        System.out.flush();
                        Runtime.getRuntime().exec("clear");
                        outStream.close();
                        printStream.close();
                    } catch (IOException e1) {
                        e1.printStackTrace();
                    }
                    Thread.sleep(1000);
