deduction is especially useful when you declare a constant or variable and give the initial value type. This is usually done by assigning constant values to the declared constants or variables.　　For example, you would declare a user-name string constant and assign him a value called "JSON."Let UserName = "json"　　You do not have to specify what type, at compile time, the constant username is automatically set to the type of the assigned value through the mechanism of type deduction.　　　　　　2. What

, but not so obvious, the reason is not obvious because the uniq command can only go to repeat the row, not the full text to weight , So to achieve the desired effect, we first sort:history | cut -c 8- | cut -d ‘ ‘ -f 1 | sort | uniq# 或者$ history | cut -c 8- | cut -d ‘ ‘ -f 1 | sort -uThis is the place where Linux/unix philosophy attracts people, and it is a command to do only one thing but to the best. Output duplicate rows # 输出重复过的行（重复的只输出一个）及重复次数$ history | cut -c 8- | cut -d ‘

In Java, you declare a common class that lends the main () method. The program executes from the first statement of the main () method, followed by a subsequent statement, until it reaches the end of the-main () method at the end of the program. However, in programming, we often need to change the program control process, that is, the order of execution of statements. There are three basic techniques that c

Introduction to the Callback control process in JavaScript, javascriptcallback Callback, which is everywhere in javascript, is a disaster for process control and has obvious disadvantages: 1. There is no explicit return, which is prone to redundant processes and bugs.2. The code is infinitely nested and hard to read. N

Old wolf's words: David Kline is a very good developer in the. net cf team. He has seen this series of articles for a long time and has never been able to translate them. Today, I used my post time to translate it. I also hope that I can make this series of articles so that more friends can understand it.

": {System.out.println ("Here is Spring Yo"); break;} Case "Summer": {System.out.println ("Here is Summer Yo"); Default:{system.out.println ("Only fall or Winter");}}There are two notable places to use when using the switch statement:1), thedata type of the expression after the switch statement can only be of type BYTE,SHORT,INT,CHAR4, string and enum type2), If you omit the break of the code block after the case, a trap is introduced. Because of this limitation, I usually rarely use the switch
