Programming from scratch: where to start? How to start learning programming from scratch in Java?

With the rapid development of computer technology, programming and website creation methods are becoming more popular and attract the attention of a huge number of people. Even a person without special education will be able to start developing programs, the main thing is the desire and desire to learn new material and constant practice.

Learning Options

Where to start learning programming from scratch? There are several ways to master new material in this area. Private teachers will show you how to start learning programming from scratch and teach you the important aspects of building code. However, this method is quite expensive, therefore, they mainly use such training methods:

1. Specialized courses. Their cost is much less than the lessons of a personal tutor. It is worth noting that many employers respond positively to the presence of a variety of certificates of completion of studies at computer academies. Pay attention to courses of the world-famous Microsoft and Cisco companies.
2. Deleted free courses. The Internet has a very large number of services with which you can view lecture courses at Oxford, Harvard, and other eminent educational institutions in the world. There are also special platforms for training practical programming skills. Read more about distance learning and useful Internet services later in the article.
3. Self-training. Where to start learning programming from scratch if you do not plan to enroll in courses and spend money? In this case, the easiest way to do self-education. You should start the study by reading the basics, do not delve into the theory, immediately begin to practice, because only in the process of creating the program will you acquire the necessary skills.

After choosing the training option that suits you, you should decide on the subject area, because programming has a fairly wide range of different branches.

How to choose a suitable direction?

The choice of a programming language directly depends on the type of software that you will create in the future:

1. Desktop programs. This type of software is designed for personal computers (different players, converters, word processors, and so on).
2. Antivirus software (virus and spyware removal software). Antivirus developers should have a general understanding of cryptography and various data encryption algorithms.
3. Applications for smartphones and tablets. The most requested branch of modern programming. Different operating systems require knowledge of their language. Articles for developers for iOS, WinPhone and Android will tell a beginner where to start learning programming from scratch for smartphones and tablets.
   

4. Gaming software for personal computers. Such games, as a rule, have a predefined script that the user must go through. To write, you need to have knowledge in the field of constructing graphic three-dimensional elements.
5. Online Games. Quite popular types of software today. Accordingly, developers are also in demand in the labor market.
6. Work with web technologies. Website development. Web programming from scratch is easy to learn, because the logic of writing sites and scripts is much easier than creating software with a complex algorithm of work.

If the most important role for you is the size of your wages, pay attention to the job market. Now, developers who specialize in the languages ​​Java, C #, ASP.NET, C ++ are considered the most popular.

Languages ​​low and high. Difference and Applications

It is believed that all programming languages ​​are divided into high-level and low-level. Low-level code is more easily processed by a computer, but writing it takes a lot of time and requires more knowledge in the subject area. Such languages ​​(for example, assembler) are used to write software for digital microcircuits and microcontrollers. They are not very convenient for learning programming from scratch. Where to start writing the first programs, they will be shown by the useful services and literature from world famous authors given in the article below.

High-level languages ​​are much easier to use, because they use built-in libraries to simplify and visualize the code. Most modern software is written using high-level languages.

Programming from scratch: where to start creating mobile applications?

The process of creating mobile programs allows programmers to work with the latest tools and, as a result, earn a decent amount of money through monetization. To begin with, you should choose the site on which you will work:

1. Google Play Application store for users of the Android operating system. This OS has the largest share of users in the market. For the development of applications and games, the java and C / C ++ languages ​​are used. The most popular applications are messengers, clients of social networks, cloud storage, games.
2. Windows Mobile Store. This store is rapidly gaining popularity along with smartphones from Microsoft. In the CIS countries, most users prefer tablets based on the Windows Phone platform. Programming applications for such a store helps to earn more money for monetization, because, unlike Android, almost all programs in the Windows store are distributed on a paid basis.
3. App Store Another profitable development platform (language - Objective-C). The process of creating programs for Apple devices requires a predefined development environment called Xcode. The next step is to learn Objective-C programming from scratch. Where to start writing code, tells David Mark's book “Learning C for Mac. Second Edition. ”

Java language

Most professional developers recommend starting with Java programming. It is easy to learn and at the same time popular in the market. Use the tips below if you decide to learn programming from scratch. Where to start Java development?

1. Learn the basic elements of code (variable declarations, conditions, loops, and so on). Knowing these basics of code will help you write complex programming logic.
2. Visit online services like HourOfCode regularly. They help to visualize the written code, which will help to better understand the development process.
   
3. Keep up to date with the latest Java versions and try to use only the latest frameworks.

Java is a high-level object-oriented programming language that is needed to develop most modern web applications and games. During the compilation process (turning the written code into a language understandable for the device), the code turns into a sequence of bytes, so the program is easy to test on any Java virtual machine.

Programming from scratch. Where to start Java and Web coding?

The Java language is widely used in web development. Before you start a full-fledged programming process, you should study Java, PHP, MySQL, HTML, CSS. A more detailed explanation of these concepts is given below:

1. Java - used in writing utilities for websites and prescribing the logic of the functionality of web pages.
2. PHP is a language for creating personal website pages. It has a script structure. The leading language in creating today's dynamic websites. PHP is needed to understand scripts and programming from scratch. Where to begin? From reading Josh Lokhat’s book “PHP: The Right Way”.
3. MySQL is a system for managing the basics of data. It is widely used in the creation of websites that require the storage of large amounts of grouped data.
4. HTML is not a programming language. This is a markup language used to write the base of a web page (building blocks, distributing text and paragraphs, and so on).
5. CSS is a cascading style sheet. It is used only in conjunction with HTML to give the language markup style and appearance.

Only by learning the basic concepts of the milestones of these technologies, you can begin to create professional dynamic websites that are in great demand today.

Web programming. Relevance and features

The topic of Web programming is especially relevant today. As mentioned above, to start developing web elements, you need to have a fairly large amount of knowledge about markup languages, creating scripts, logic, and styles.

Now you will not surprise anyone with sites that are created only using HTML and CSS, so web developers have become in demand, who are able to make the site visually beautiful, as well as fill it with all the functionality that users need.

This type of development requires the creation of two types of the same program: server and client. The programmer must understand the principle of operation of the so-called sockets - data packets that allow you to transfer the necessary information flows over the network between the server and the client.

Creating applications for the Windows operating system

To develop such programs, you will need knowledge of the C # language. A free service from Microsoft called Virtual Academy will allow you to learn all the features of this language and practice writing simple applications.

According to the new Microsoft policy, all applications are uploaded to the software store, so you can access the monetization of your project.

C language family (C, C ++, C #). Features

Programming from scratch - where to start choosing a language? The answer to this question can be obtained by delving deeper into the variety of application creation technologies. The relevance of a particular language should be taken into account.

The C, C ++, C # languages ​​have one thing in common - the presence of the OOP (object-oriented programming) function. This technology can greatly simplify the process of writing program code. Each program object is described in a particular class and has its own parameters, methods and properties. Thus, the programmer may not write huge pieces of code each time if the same object needs to be used several times.

Useful Internet services for learning the basic principles of programming and the code structure of any application

At the first stage of training, almost any web service will offer you to try your capabilities using "Pascal" - the most simple of the high-level languages. It is used for educational purposes, it is taught in schools and technical schools so that students can understand programming from scratch. Where to start Pascal coding? First of all, you need to download the development environment to your PC. This is a small executable file in which you have to write program code. Use TurboPascal, because it is the most popular learning environment for this programming language.

HourOfCode is a web service from Microsoft. It is designed to clearly demonstrate to students what a cycle, variable, class, condition is. The learning process is like a game.

CodeAcademy is a powerful resource for learning almost any coding technology. Spending just an hour a day, you won’t even notice how you learn to program and create your own projects.

Udacity is a service that provides its users with free access to lectures by eminent professors and developers.

Getting the initial experience. Freelance

After learning the basic principles of your chosen language, you can safely proceed to your first projects. Start freelance, because this is how you fill your portfolio and gain experience with customers. Such skills will come in handy in the future if you want to get a job as an official software developer in a company.
