Answer 2

自己搞定了. 下面是方法.方法一
這是比較基本的方法 JEditPane XD = new JEditPane();
XD.setEditorKit(new HTMLEditorKit());
XD.setText("<h1>zz</h1>");[編輯]方法二
方法一最大的缺點在於說，如果你有一狗票的 html 內容，要這麼傻傻地用 setText() 的方式去輸入嗎？當然有別的方法。首先我們另外寫一個 html 檔，暫且稱之為「sample.html」，接著用 InputStreamer 去讀取它。          JEditPane XD = new JEditPane();
         XD.setContentType("text/html");
         HTMLEditorKit kit = new HTMLEditorKit();
         XD.setEditorKit(kit);         HTMLDocument doc = (HTMLDocument)XD.getDocument();
         File f = new File("sample.html");
         try {
             FileInputStream reader = new FileInputStream(f);
             kit.read(reader,doc,0);
         }catch(Exception e) {
             e.printStackTrace();
         }
