本文整理了Java中java.net.SocketException类的一些代码示例，展示了SocketException类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。SocketException类的具体详情如下：
包路径：java.net.SocketException
类名称：SocketException

SocketException介绍

[英]This SocketException may be thrown during socket creation or setting options, and is the superclass of all other socket related exceptions.
[中]此SocketException可能在套接字创建或设置选项期间抛出，它是所有其他与套接字相关的异常的超类。
