本文整理了Java中java.net.Socket.<init>()方法的一些代码示例，展示了Socket.<init>()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。Socket.<init>()方法的具体详情如下：
包路径：java.net.Socket
类名称：Socket
方法名：<init>

Socket.<init>介绍

[英]Creates a new unconnected socket. When a SocketImplFactory is defined it creates the internal socket implementation, otherwise the default socket implementation will be used for this socket.
[中]创建新的未连接套接字。定义SocketImplFactory时，它将创建内部套接字实现，否则将对此套接字使用默认套接字实现。
