〔Other〕请帮我加个标题

每次写的随笔�Q�标题可不可以自动加上我选择的个人分�c�？不然�Q�我每次看到标题�Q�有时也犯迷�p�：(x��)“这写的啥玩意这是？�?br />
比如某篇随笔的标题是“增加功能”，属于“Java”和“Windows”分�c�，那么保存后显�C�的标题是“〔Java〕〔Windows〕增加功能�?br />
应该很好处理的，�q�可以设�|�括��L(f��ng)��样式�{�等

如果建立服务监听不成功，说明已经有实例（其它�E�序�Q�）(j��)占用此端口了(ji��n)�Q�向此端口发送数据唤醒前一个实例，停几�U�以便前一个实例接受，然后退出�?
