java服务器源代码 服务器源码是什么

socket JAVA 源代码

很久以前做的了，启动程序两次，在单选框中选服务器点连接(一定要先点服务器-连接)，在在另外一个界面中选客户端点连接；

Java网站的源代码怎么在本地运行

首先 java网站是基于jdk运行的。你得先装jdk。去官网下载一个jdk安装。然后你得编译你的项目，打包到容器（tomcat,weblogic,jboss等）中运行即可。再提醒一下就是，看看你的源代码有木有用到数据库或者其他类型的服务。如果有的话，你得装数据库或服务，并且初始化数据。再启动你的你的容器。

java 服务器代码倒出来,就是源码吗?

是的。因为源代码，gitlab上下载的代码，后缀名是java的就是源代码，可以用IDEA打开查看，查看某个方法可以实现跳转。所以java服务器代码倒出来，就是源码。
