What do C programmers think of Java
Which programming languages are in demand?
PHP, C ++ or do you prefer Java? Which programming, script or query languages should you learn?
Anyone who wants to learn to program and make a career as a programmer cannot avoid having a good command of two or three programming languages. But which ones are particularly in demand in which areas? Which ones should you keep your hands off of? There is a reliable basis for the ranking of the most popular programming languages: the number of job advertisements and the amount of salaries paid.
The basics - Java, C, C ++ and C Sharp
Java is probably the most frequently used programming language of the current time. No wonder, because it enables platform-independent applications to be developed for a wide range of purposes. All you need is a text editor and the Java SE Development Kit, which is available for all common operating systems. Since Java is an object-oriented programming language, the actual programming is made much easier. So Java is also extremely accessible for beginners and therefore easy to learn or it is recommended to start with a programming language like Java, as there are tutorials a dime a dozen and you can internalize object-oriented programming directly.
Developed as early as the 1970s, C is one of the oldest programming languages. This is a machine-oriented language that enables you to work with the often feared "pointers". This can lead to serious security problems or just endless bugs, but it also makes C very powerful. For this reason, it is still one of the most important programming languages in the world today. Computer scientists with C knowledge are particularly popular in the area of embedded systems, mechanical engineering and the automotive industry. It is also an excellent basis for learning more complex languages.
C ++ is just as powerful. C ++ enables efficient and machine-oriented programming as well as programming at a high level of abstraction. It "expands" C and Java with meaningful content, such as manual memory management and pointer arithmetic, which make for greater complexity and the associated error-proneness. On the other hand, it gives you significantly more freedom than e.g. Java, so that you can easily program with it for computers and machines of any kind. This means that you always work on the basis and learn other languages much faster.
C # (C Sharp) was only developed by Microsoft in 2001 and is therefore a comparatively young programming language. With it you can program numerous applications for the Microsoft operating system. Thanks to Xamarin, it is now also possible to program with C # for Android, iOS and macOS. Like Java, C # is an object-oriented programming language with imperative programming. Due to their syntactic similarity, you will find similar concepts in both languages.
Ruby is a programming language that has been experiencing a renaissance in recent times and, due to its simplicity, is ideal for beginners and newbies. It is used to pull up projects quickly and thus to be able to present a first functional application. Ruby is particularly popular in the start-up industry, as it is quick to learn, but still offers numerous application possibilities.
Data Analytics and Artificial Intelligence - Python and R
Data analysis, statistics, web development, apps: Python is as extensive as it is versatile and is therefore suitable for numerous fields of application. Especially in the area of machine learning and the analysis of large amounts of data, Python has now become the quasi-standard. Large corporations, institutional research institutions and medium-sized companies therefore increasingly need IT specialists with the appropriate expertise. Knowledge of Python is a mandatory requirement, especially in the field of artificial intelligence or in the Internet of Things.
Similar to Python, R is used in the area of big data. Business and science use static methods to analyze large amounts of data as an important basis for decision-making. R is especially predestined for this and enables the free calculation of statistics and graphics. In contrast to Python, however, the focus is exclusively on data analysis, which is why additional functions provide more flexibility and variety in this area.

Process databases correctly - SQL
SQL stands for "Structured Query Language" and comprises the structured query of databases. This includes, for example, inserting, changing and querying data records. Due to the simple syntax and semantics, SQL is relatively easy to learn. Therefore it is supported by almost all common database systems. This makes SQL one of the basic tools of a developer. However, since this is a relatively special use case, pure SQL programmers are rare. Instead, combinations, especially with PHP and Java, are a coveted skillset among employers.
The 5 most popular programming languages
Number 4: C ++ - The language for experts
Although it has been around for a few years, C ++ is still considered a modern language thanks to constant further development. The language was developed in the USA in the early 1980s and contains many elements of the C. C ++ language is an object-oriented language. This means that the properties of certain classes and methods can be inherited; the inheriting class is called the base class, and the inheriting class is called a derived class. It's a bit tricky, but it saves a lot of development work. The code is translated, which speeds up execution enormously. C ++ is considered a general-purpose language, but is often used for special tasks and for time-critical applications. In contrast to C #, there are no design elements for a user interface integrated in C ++, but C ++ programs work without problems with other languages. This language is only suitable to a limited extent for learning to program.
Number 3: C # - Major programming language in the Microsoft universe
Since 2000, C # has been the most important programming language in Microsoft's .NET framework alongside Visual Basic. C # is not necessarily suitable for starting a career, but anyone who can demonstrate C # knowledge has already created important prerequisites for a career as a .NET programmer. C # has many features and was developed as a direct competitor to Java. C # and C ++ also coexist peacefully. The programming language is suitable for all types of applications and is often used for computer games, utilities, operating systems and compilers. The current version is part of the Microsoft Visual Studio development environment. Knowledge of object orientation is also essential for programming with C #. Outside of the .NET environment, language hardly plays a role.
Number 2: PHP is used on most web servers
PHP is the recursive abbreviation of "PHP: Hypertext Preprocessor." It's called a recursive abbreviation because the first word is the same as the abbreviation. The computer language is found on almost all web servers and is used by developers to create dynamic and, in connection with (My) SQL, database-based web pages. The programming language can also perform calculations and conversions or work with date and time and collect information from online forms. PHP can also change the appearance of the page and create graphics. In this server-side scripting language, the code is typically embedded in HTML code to perform functions that HTML cannot.
Number 1: Java tops them all
If you want to learn to program to start your career, there is no getting around Java. Java is a so-called "high-level" or higher programming language. This means that the language is suitable for all applications and that the instructions can be read and changed by people. The language emerged in the early 1990s and was originally intended for use on mobile devices such as cell phones. But the focus of use shifted more and more towards the Internet. Today Java provides extensive end-uses on client computers and more interactivity of websites and gives developers the possibility to produce animated websites. Many features have been transferred from C ++ to Java, whereby the complexity of the C ++ programs has been reduced at the same time. This also reduced the likelihood of serious errors that are often found in C ++. Other advantages of Java are reliability, security and platform independence. Knowledge of Java is essential for a professional career.
Almost every year new languages are added, others disappear, fall off the popularity list or are only suitable for certain purposes. Programming languages such as PHP, Ruby or Java are constantly being developed. New languages such as Go, Scala or Python are becoming increasingly popular. Others perform special tasks such as Swift, which is particularly suitable for mobile devices. Anyone who has mastered two of the most important programming languages to start their job and their career should have good chances on the job market.
