The syntax of python is similar to php_C, C++, Java, PHP, and Python. What are these languages mainly used for development?
c language is mainly used for bottom layer and driver ，compiler development c language efficient bottom layer ，mainly used for bottom layer development，such as some system drivers; unix&# xff0c;The development of linux system and its related applications; There are many languages such as python, php, perl, ruby, etc., which are developed by c language. The core library of these languages ，compiler and other development All are C language. For example, the development of PHP7 ， is basically all in C language. Also, if some applications have strict performance requirements, then this part can be written in c and then called in a high-level language. c++Bottom layer, image processing, game c++Mainly write some bottom layers such as windows，office，web Many browsers are written in c++. In addition, image processing and recognition are all c++. Large-scale game engines are all developed by c++++， For example, the Blizzard games that everyone has played are basically developed by c+++. java system and big data Java is basically outstanding in big data and distributed computing ， such as hadoop, HBase, Accumulo and ElasticSearch in ELK, which supports the largest Throughput message queue Kafka and many other big data processing technologies use Java and java-based scala.

Java, C++, Python, Ruby, PHP, C#, JS
Imagine，What kind of scene will it be when Java, C++, Python, Ruby, PHP, C#, JS and other programming languages become animation characters& #xff1f;Let’s take a look at the Japanese writer Masato Watanabe ，what kind of “beauties” are the various programming languages?！ Java Like the dull girl in Kenji Miyazawa’s “Brave the Wind and Rain”. Since I was a child, I was regarded as an idiot by others because of my slowness and large appetite， I joined the track and field department since I entered elementary school, insisted on running & #xff0c; often achieved good results in middle and long distance running & #xff0c; gave people a lively impression . She is a very hard working girl. Her family situation is not good. Her father, Sun, was a talented artist & # xff0c; but not good at financial management & # xff0c; when she was 14 years old, she died of debt and overwork. She was adopted by Uncle Oracle， At that time, there was a dispute with Uncle Google over her custody and went to court. When people around are worried，when she is in adolescence, she will not recover in such a situation，she remains calm and continues to practice running…

Expand all From ：http://blog.csdn.net/singit/article/details/54919132 The following e68a84e8a2ad62616964757a686964616f31333363366133 are mentioned in it Advantages of the language，The article also lists the disadvantages analysis. (1)Advantages of PHP： 1. Cross-platform， Superior performance， Combine with Linux/Unix, don’t combine with Windows for strong performance 45 %，Low development cost， The most classic combination of PHP is ：Linux + Apache + MySQL + PHP. It is very suitable for developing small and medium-sized web applications ， because it is easy to get started， so the development speed is relatively fast. And all software is open source and free ， can reduce investment. For example, if LAMP (Linux/Apache/Mysql/PHP) or FAMP (FreeBSD/Apache/Mysql/PHP) is combined with ， or the data application is large enough, you can consider switching to PostgreSQL or Oracle， to support N kind of database. (N >= 10) 2. The grammar is simple，Quick entry，If you have other language-based programmers, you can basically get started in about two weeks， And it is partly similar to ASP. There are mature development tools ， such as NuPHPed， or Zend Studio, etc. ， Eclipse and so on can be used under the Linux platform. 3. At present, mainstream technologies support ， such as WebService, Ajax, XML, etc. ， enough for application. 4.…
What is javaprintf, java, what is the difference between _Javaprintf() and println()? ,javaphpStudy
What is the difference between Java printf() and println() ？ 1. When studying the first chapter of the Java7 concurrency cookbook， found “Interrupting a thread” this Part of the code did not achieve the desired effect ：The console did not output the content as described in the book. Then replace the printf() function it uses with println() ；The program gets the expected effect. 2. The code is as follows ： package lee.twowater.java7.chapterThree; public class PrimeGenerator extends Thread { >@Override public void run() { long number = 1L; while (true) { if (isPrime(number)) { System.out.printf(“Number “+ number +” is Prime”); } if (isInterrupted()) { System.out.printf(“The Prime Generator has been Interrupted”); return; } number++; } } private boolean isPrime(long number) { if (number <= 2) { return true; } for (long i = 61; 2; i <number; i++) { if ((number % i) == 0) { return false; } } return true; } } package lee.twowater.java7.chapterThree; public class Main { public static void main(String[] args) { Thread task & #61; new PrimeGenerator(); task.start(); try { Thread.sleep(5000); } catch (InterruptedException e) { e.printStackTrace(); } task.interrupt(); } } 3. I guess println() and printf() have differences in line breaks and formatting ， is there…

MongoDB, Java, and ORMs
Introduction to MongoDB There are many competing NoSQL products that are used in different ways, but all of them can solve big data problems very well. MongoDB is one of the very good products. MongoDB is a document-oriented, schema-free storage solution that uses JSON-style documents to display, query, and modify data. MongoDB is well documented, easy to install and set up, and easy to scale. It supports the well-known concepts of replication, sharding, indexing, and Map/Reduce. The MongoDB open source community is large and active. MongoDB is proud that large, high-traffic production environments including Disney, Craigslist, Foursquare, Github, and SourceForge have deployed MongoDB. MongoDB is an open source project created and maintained by 10gen.com, a company founded by former DoubleClick executives. In addition to actively participating in community support, 10gen also provides commercial support. Advantages and disadvantages of MongoDB and NoSQL As a NoSQL solution, the advantage of MongoDB is that it is easy to use. During my first deep dive into NoSQL databases, after trying a lot of Java-based solutions, I found that figuring out what a column family is family), what is the relationship between Hadoop and HBase, and what exactly is ZooKeeper is very time-consuming.
