Add any JSR 303 implementation to your classpath. Popular one used is Hibernate validator from Hibernate. <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-validator</artifactId> <version>4.2.0.Final</version> </dependen...

We will start with creating a simple node application with a basic structure and then connecting with local sql server database and performing some queries on that database. Step 1: Create a directory/folder by the name of project which you intent to create. Initialize a node application using npm ...

Referring to non-static members in initializer lists before the constructor has started executing can result in undefined behavior. This results since not all members are constructed at this time. From the standard draft: §12.7.1: For an object with a non-trivial constructor, referring to any no...

webpack-dev-server can proxy some requests to others servers. This might be useful for developing API client when you want to send requests to same domain. Proxy is configured via proxy parameter. Example configuration of dev server passing requests to /api to other service listening on port 8080 ...

There are different approaches to the installation of SFML on Linux: Install it directly from your distribution's package repository Get the source code, build it and install it Download the precompiled SDK and manually copy the files Option 1 is the preferred one; if the version of SFML tha...

The most common way to install SFML on windows is to download the official SDK You can then unpack the archive and use it in your environment of choice. vcpkg Although it's still heavily in development, if you use Visual studio 2017 or newer, you can also install SFML via vcpkg which integrates w...

First of all you need to download the SFML SDK. Then, in order to start developing SFML applications, you have to install the following items: Header files and libraries SFML is available either as dylibs or as frameworks. Only one type of binary is required although both can be installed simultan...

Simple Codec Here to illustrate the working principle we can use simple encryption and decryption as follows. public static String encrypt(String input) { // Simple encryption, not very strong! return Base64.encodeToString(input.getBytes(), Base64.DEFAULT); } public static String dec...

For example, say below is the sample data in an Excel 'Test', Purchase_Date Customer_Name Price 05-05-2017 Adam 1075 06-05-2017 Noah 1093 07-05-2017 Peter 1072 08-05-2017 Louis 1101 09-05-2017 Zoe 1248 10-05-2017 Kevin 1045 11-05-2017 Messiah 1...

This is project directory. A service endpoint interface First we will create a service endpoint interface. The javax.jws.WebService @WebService annotation defines the class as a web service endpoint. import javax.jws.WebMethod; import javax.jws.WebService; import javax.jws.soap.SOAPBi...

The example below uses the input statement to read a value from a source (in this case the string 123) into a both a character destination and a numeric destination. data test; source = '123'; numeric_destination = input(source, best.); character_destination = input(source, $3.); run; ...

Magics whose name begins with just one % take as argument the rest of the line and are called line magics. Magics that begin with a double percent sign %% take a multi-line argument and are called cell magics. A commonly used magic is %timeit, a wrapper around the Python's timeit.timeit function, f...

We have a Student table with SubjectId. Here the requirement is to concatenate based on subjectId. All SQL Server versions create table #yourstudent (subjectid int, studentname varchar(10)) insert into #yourstudent (subjectid, studentname) values ( 1 ,'Mary' ) ,( 1 ,'John' ...

In case of SQL Server 2017 or vnext we can use in-built STRING_AGG for this aggregation. For same student table, create table #yourstudent (subjectid int, studentname varchar(10)) insert into #yourstudent (subjectid, studentname) values ( 1 ,'Mary' ) ,( 1 ,'John' ) ,( 1 ...

apcu_cache_info provides information about the store and its entries: print_r(apcu_cache_info()); Note that invoking apcu_cache_info() without limit will return the complete data currently stored. To only get the meta data, use apcu_cache_info(true). To get information about certain cache ...

The APCUIterator allows to iterate over entries in the cache: foreach (new APCUIterator() as $entry) { print_r($entry); } The iterator can be initialized with an optional regular expression to select only entries with matching keys: foreach (new APCUIterator($regex) as $entry) { pr...

The List interface is implemented by different classes. Each of them has its own way for implementing it with different strategies and providing different pros and cons. Classes implementing List These are all of the public classes in Java SE 8 that implement the java.util.List interface: Abs...
