. setgroupingcomparatorclass. As long as the two keys compared by this comparator are the same, they belong to the same group and their values are placed in a value iterator, the iterator uses the first key of all keys in the same group. Finally, it enters the reduce method of CER Cer. The input of the reduce method is all (key and Its Value iterator ). Also note that the input and output types must be consistent with those declared in the Custom CER Cer.

Next we can look at the deeper things written by others on the Internet. Those fancy things are icing on the cake, and the framework will soon be ready for other things. The most current socket programming in windows. But what I need to say is that in actual work, the server basically talks about UNIX. However, the basi

Use the best Selector
When using JQuery, you can use multiple selectors to select the same element. The performance of different methods is different. Sometimes the difference is very large. Commonly used selectors include the following:
Based on experience, we should know that the performance of these five selectors is declining in turn. Let's take a test to see how different their performance is:

Let's explain how to use the completed port from Microsoft.If you have used programming, you will naturally know what is going on. You will not read it again at a time and learn it without him or herself.Luxury talks about efficiency and so on, it's just a coincidence.
This is an example in the console. It is an echo server,After running, it will listen on port 5150. Once a port is connected, it sends data to the Service port, and it returns the data
