<div class="block">
<span>类EnumSyntax是提供所有“类型安全枚举”对象的通用实现的抽象基类。</span>
<span>枚举类（扩展类EnumSyntax）提供了一组枚举值（对象），它们是枚举类的单例实例;</span>
<span>例如：</span>
<pre>  <span>public class Bach extends EnumSyntax {
         public static final Bach JOHANN_SEBASTIAN     = new Bach(0);
         public static final Bach WILHELM_FRIEDEMANN   = new Bach(1);
         public static final Bach CARL_PHILIP_EMMANUEL = new Bach(2);
         public static final Bach JOHANN_CHRISTIAN     = new Bach(3);
         public static final Bach P_D_Q                = new Bach(4);

         private static final String[] stringTable = {
             "Johann Sebastian Bach",
              "Wilhelm Friedemann Bach",
              "Carl Philip Emmanuel Bach",
              "Johann Christian Bach",
              "P.D.Q. Bach"
         };

         protected String[] getStringTable() {
             return stringTable;
         }

         private static final Bach[] enumValueTable = {
             JOHANN_SEBASTIAN,
              WILHELM_FRIEDEMANN,
              CARL_PHILIP_EMMANUEL,
              JOHANN_CHRISTIAN,
              P_D_Q
         };

         protected EnumSyntax[] getEnumValueTable() {
             return enumValueTable;
         }
     }</span> </pre>
<span>然后，您可以编写使用<code>==</code>和<code>!=</code>运算符来测试枚举值的代码;</span>
<span>例如：</span>
<pre>  <span>Bach theComposer;
     . . .
     if (theComposer == Bach.JOHANN_SEBASTIAN) {
         System.out.println ("The greatest composer of all time!");
     }</span> </pre>
<span>枚举类的<code>equals()</code>方法只是对相同的对象进行测试（ <code>==</code> ）。</span>
<p> <span>您可以通过调用<a href="../../../javax/print/attribute/EnumSyntax.html#toString--"><code>toString()</code></a>将枚举值转换为字符串。</span> <span>该字符串从枚举类提供的表中获取。</span> </p>
<p> <span>在引擎盖下，枚举值只是一个整数，枚举类中每个枚举值是不同的整数。</span> <span>您可以通过调用<a href="../../../javax/print/attribute/EnumSyntax.html#getValue--"><code>getValue()</code></a>获取枚举值的整数值。</span> <span>构建枚举值的整数值（见<a href="../../../javax/print/attribute/EnumSyntax.html#EnumSyntax-int-"><code>EnumSyntax(int)</code></a> ）。</span> <span>由于构造函数被保护，唯一可能的枚举值是在枚举类中声明的单例对象;</span> <span>在运行时无法创建其他枚举值。</span> </p>
<p> <span>您可以定义枚举类的子类，并将其扩展为附加枚举值。</span> <span>子类的枚举值的整数值不需要与超类的枚举值的整数值不同;</span> <span>该<code>==</code> ， <code>!=</code> ， <code>equals()</code>和<code>toString()</code>方法仍然正常工作，即使子类使用一些相同的整数值作为超的。</span> <span>但是，使用枚举类和子类的应用程序可能需要在超类和子类中具有不同的整数值。</span> </p>
