（1） 如果第二个和第三个操作数具有相同的类型，那么它就是条件表达式的类型。
（2） 如果一个操作的类型是T，T表示byte、short或char，而另一个操作数是一个int类型的“字面常量”，并且它的值可以用类型T表示，那条件表达式的类型就是T。
（3） 否则，将对操作数类型进行提升，而条件表达式的类型就是第二个和第三个操作被提升之后的类型。

l          希望某类或者某已知MIME 类型的文件（比如：*.gif;*.txt;*.htm）能够在访问时弹出“文件下载”对话框。
l          希望客户端下载时以指定文件名显示。
l          希望某文件直接在浏览器上显示而不是弹出文件下载对话框。

对于上面的需求，使用Content-Disposition属性就可以解决。下面是代码示例：

1、装载；2、链接；3、初始化；4、初始化；5，实例化（创建新的实例）
实际上，static块的执行发生在“初始化”的阶段。初始化阶段，jvm主要完成对静态变量的初始化，静态块执行等工作。
下面我们看看执行static块的几种情况：
