# 使用 SDK for Java 2.x 的 Amazon SES 示例
<a name="java_2_ses_code_examples"></a>

以下代码示例向您展示了如何在 Amazon SES 中使用来执行操作和实现常见场景。 AWS SDK for Java 2.x 

*操作*是大型程序的代码摘录，必须在上下文中运行。您可以通过操作了解如何调用单个服务函数，还可以通过函数相关场景的上下文查看操作。

*场景*是向您演示如何通过在一个服务中调用多个函数或与其他 AWS 服务结合来完成特定任务的代码示例。

每个示例都包含一个指向完整源代码的链接，您可以从中找到有关如何在上下文中设置和运行代码的说明。
