<p class="article"> 如果你想初始化實例變量并且不能在初始化塊中進行初始化的時候，你可以來類的構造函數中進行初始化。假如erroeStrings束是一個實例變量而不是一個類變量，你可以使用下面的代碼來進行初始化：
</p>
<p class="article">import java.util.ResourceBundle;</p>
<p class="article">class Errors {</p>
<p class="article"> ResourceBundle errorStrings;</p>
<p class="article"> Errors() {</p>
<p class="article"> try {</p>
<p class="article"> errorStrings = ResourceBundle.</p>
<p class="article"> getBundle("ErrorStrings");</p>
<p class="article"> } catch (java.util.MissingResourceException e)
{</p>
<p class="article"> // 這里是錯誤恢復代碼</p>
<p class="article"> }</p>
<p class="article"> }</p>
<p class="article">}</p>
<p class="article">初始化errorStrings的代碼現在處在類的構造函數中。</p>
