本文整理了Java中java.net.URL.getProtocol()
方法的一些代码示例,展示了URL.getProtocol()
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。URL.getProtocol()
方法的具体详情如下:
包路径:java.net.URL
类名称:URL
方法名:getProtocol
[英]Returns the protocol of this URL like "http" or "file". This is also known as the scheme. The returned string is lower case.
[中]返回此URL的协议,如“http”或“文件”。这也被称为计划。返回的字符串是小写的。

* that is, has protocol "file" and ends with the ".jar" extension.
* @param url the URL to check
* @return whether the URL has been identified as a JAR file URL
