Overview
Java programming language was originally developed by Sun Microsystems which was initiated by James Gosling and released in 1995 as core component of Sun Microsystems’ Java platform (Java 1.0 [J2SE]). The latest release of the Java Standard Edition is Java SE 8. With the advancement of Java and its widespread popularity, multiple configurations were built…

Environment Setup
Setting up Fortran in Windows G95 is the GNU Fortran multi-architechtural compiler, used for setting up Fortran in Windows. The windows version emulates a unix environment using MingW under windows. The installer takes care of this and automatically adds g95 to the windows PATH variable. You can get the stable version of G95 from here AD…

Overview
Fortran, as derived from Formula Translating System, is a general-purpose, imperative programming language. It is used for numeric and scientific computing. Fortran was originally developed by IBM in the 1950s for scientific and engineering applications. Fortran ruled this programming area for a long time and became very popular for high performance computing, because. It supports…

HTML DOM
Every webpage resides inside a browser window which can be considered as an object. A Document object represents the HTML document that is displayed in that window. The Document object has various properties that refer to other objects which allow access to and modification of document content. The way a document content is accessed and modified is…

Unit Testing
Unit Testing involves testing every individual unit of an application. It helps the developer to test small functionalities without running the entire complex application. The Dart external library named “test” provides a standard way of writing and running unit tests. Dart unit testing involves the following steps − Step 1: Installing the “test” package To installing third-party…

Libraries
Elixir provides excellent interoperability with Erlang libraries. Let us discuss a few libraries in brief. The Binary Module The built-in Elixir String module handles binaries that are UTF-8 encoded. The binary module is useful when you are dealing with binary data that is not necessarily UTF-8 encoded. Let us consider an example to further understand…

Concurrency
Concurrency is the execution of several instruction sequences at the same time. It involves performing more than one task simultaneously. Dart uses Isolates as a tool for doing works in parallel. The dart:isolate package is Dart’s solution to taking single-threaded Dart code and allowing the application to make greater use of the hard-ware available. Isolates, as the name suggests, are…

Async
An asynchronous operation executes in a thread, separate from the main application thread. When an application calls a method to perform an operation asynchronously, the application can continue executing while the asynchronous method performs its task. Example Let’s take an example to understand this concept. Here, the program accepts user input using the IO library. The readLineSync() is a synchronous method. This…

Errors Handling
Elixir has three error mechanisms: errors, throws and exits. Let us explore each mechanism in detail. Error Errors (or exceptions) are used when exceptional things happen in the code. A sample error can be retrieved by trying to add a number into a string − When the above program is run, it produces the following…

Libraries
A library in a programming language represents a collection of routines (set of programming instructions). Dart has a set of built-in libraries that are useful to store routines that are frequently used. A Dart library comprises of a set of classes, constants, functions, typedefs, properties, and exceptions. Importing a library Importing makes the components in…
