我正在研究一个简单的java tcp聊天服务器。用户可以输入“push:”,“get”,“adios”,“help”等命令。 。 。我通过设置String Line = input.readLine()来检查这些用户命令(如下所示)。问题是当我输入“push:”时,我必须去换一个新的行来获取新的输入并将其分配给一个新的字符串。我希望能够在用户输入命令后在同一行上获得输入。从同一行读取多个输入。
例如:如果用户1种类型在“推送” +“你好,你今天怎么”我想存储“你好,今天好吗?”到一个数组,以便以后可以打印它的内容。但现在,我必须输入“push:”,然后输入“Hello,今天好吗?”将其存储到数组中。这只是尴尬。有什么方法将输入存储到同一行上的两个不同的字符串?
这里是我的服务器代码,检查运行方法

看起来不错,谢谢。 – user1174834 2012-01-30 20:10:31
