在while循环之后将所有输出行添加到一个JOptionPane窗口

Question

我正在尝试将正则表达式解析的txt文件中的所有输出记录添加到一个JOptionPane窗口。我创建了一个要捕获的字符串，但我继续打印单个窗口。有任何想法吗？感谢

    while ((line = br.readLine()) != null) {

        if (Pattern.matches(titlePattern, line)) {
            String name = "", price="";
            String patternName = "title=\".*?(\")";
            Pattern r = Pattern.compile(patternName);
            Matcher m = r.matcher(line);
            if (m.find( )) {
                name = m.group(0);
                //System.out.println("Title: " + name.substring(7, name.length()-1));
            }

            String patternPrice = "Suggested Retail Price:.*?\"";
            String strOutput;

            r = Pattern.compile(patternPrice);
            m = r.matcher(line);
            if (m.find( )) {
                price = m.group(0);
                //System.out.println("Title: " + name.substring(7, name.length()-1) + ", " + price.substring(0, price.length()-1));
                //JOptionPane.showMessageDialog(null, "Title: " + name.substring(7, name.length()-1) + ", " + price.substring(0, price.length()-1));
                final_list.addElement("Title: " + name.substring(7, name.length()-1) + ", " + price.substring(0, price.length()-1));
                strOutput = "Title: " + name.substring(7, name.length()-1) + ", " + price.substring(0, price.length()-1);
                JOptionPane.showMessageDialog(null, strOutput);
            }


        }
    }

尝试使用java.swing.TextArea构建消息，并JOptionPane显示消息。这是简短的演示：

public static void main(String[] args) {
        TextArea textView = new TextArea();
        textView.append("dsddd");
        textView.append("jsdjsd");
        textView.append("qwoqwo");
        JOptionPane.showMessageDialog(null, textView);
    }
