Tontie For J2ME

不知道大家知道不知道Tontie 看名字可以有點陌生 讓我們看一下底下這個link 知道了吧 就是這個好玩的Game 好玩的是 Tontie有J2ME的版本耶!! 真是太Cool了
  • ScreenShot：
  • Cheat：
    • Press * Full health
    • Press # 1000 gold
    • Press Clear Go to the shop
    • Press Send Next level看起來是不相當好玩的樣子呢~~
而且 他還是OpenSource的喔! 可以把原始碼拿來研究一下 也可以自己寫個Tontie一類的應該滿cool的 趕快來去網站看一下http://tunah.net/~tunah/tontie/

PO文範本

由於預設的自動換行格式會很奇怪地加上許多換行的<br />標籤
造成版面不好控制
所以之後大家就直接用標準的XHTML語法來po文章吧
最簡單的方式就是在每一行後面，加上換行的<br />標籤
我也幫大家準備了一個範本
大家po完文章記得把這些文字弄掉喔~ :) 

<!-- 範本
段落：<p></p>
換行：<br />
固定格式：<pre></pre>
超連結：<a href=""></a>
加強：<em></em>
強調：<strong></strong>
有序列表：
<ol>
  <li></li>
</ol>
無序列表：
<ul>
  <li></li>
</ul>
表格：

超好用工具

下面是我目前推薦大家寫Java程式使用的工具
  1. Java IDE：Eclipse(3.0.1)
  2. UML Design Tool：Together Community Edition for Eclipse(6.3)
  3. GUI Builder：Jigloo SWT/Swing GUI Builder for Eclipse and WebSphere (3.0.1)

學會它們，你寫程式起來會很Happy
不會它們，你寫程式起來就不會那麼Happy
大家要瞭解這個重要性啊~

有關Eclipse的教學
可以看看我Blog裡面的內容
也可以看看JavaWorld@tw的相關討論喔~
大家加油吧~ :)
