Freelance IT engineer: Will Java programmers become obsolete? Current demand and future potential Explanation of reasons for high unit price

Freelance

Java programmers and engineers are currently in high demand as a language, and for this reason, the unit price is high and there are many people who are active, so there is a future. The workload has remained very high throughout the 2000s. However, things are good now, but what will happen in the future? The future will also be summarized in the article.

What was the history of Java like?

Java was started by Sun Microsystems in the early 1990s, but at the time it was called Oak, not Java. However, after that, due to problems with trademark rights, it was released to the world under the name Java, and this name is still used today. In 1999, a restructuring of Java began and Java SE was developed. Java SE enables the development of Java applications that run not only on desktops and servers, but also on today’s demanding embedded systems. Java EE was also developed. Java EE provides a low-risk platform with rich functionality. And then came Java ME. Java ME was a platform for applications running on embedded devices such as mobile phones, personal digital assistants and mobile devices.

In the 2000s, the demand for Java increased at a stretch, and the number of developers exceeded 4 million. As a result, software that makes full use of Java will appear. In 2007, Google announced Android, which adopted Java for application development. Java will continue to evolve in the 2010s. Java 7 was released in 2013, and Java 8 was released in 2014, and functions that meet the needs of the times continue to be implemented.

What are the characteristics of Java?

Some of the features of Java are as follows. The latest situation is global trends, making it easy to change jobs and easy to learn. There is a wide range of choices. If you have knowledge, your market value will be high, and you will be useful for a long time even in large-scale development, and the working environment is good as there are many places to work. It is possible to advance your career, and it is also recommended to obtain qualifications at the same time. If you can also do things like javascript, you can earn a very stable income.

versatility

Java is one of the most versatile programming languages. There are general-purpose programming languages, but Java is especially versatile. History has proven that it is a language used in a variety of systems.

Large number of cases

Since it is a highly versatile programming language, the amount of work involved is overwhelming. Engineers have a fair amount of choice in their work, so they don’t have to worry about it. The skills required of engineers change depending on the content being developed, but the demand for these skills is outstanding.

Object-orientation

Object-oriented is a programming concept that relates objects to each other and assembles them. In order to create a program using Java, you need to understand this object orientation and create a program.

Average Annual Salary in Java

Java is in high demand. The following is the annual income of the entire programmer of salaried workers and temporary employees in the job box. As you can see, you should be able to understand that it is surprisingly low. But when it comes to freelancing, things change.

Source : 求人ボックス

Freelance Java programmers earn between 500,000 and 600,000 per month. As a result, annual income can reach close to $70,000. However, this is only the annual income of veteran class with a lot of practical experience, and it will be very low if you have no experience or little practical experience. In recent years, the following concerns have arisen.

too many technicians

In recent years, the number of Java engineers has increased rapidly, and the market value has started to decline. The amount of work itself is very high, but it is becoming oversupplied, suggesting that income may decrease.

The number of cases decreased slightly

The number of Java projects tends to decrease year by year. As mentioned above, the number of projects is slightly decreasing compared to the large number of engineers, so it is possible that the annual income will decrease in the future.

The future of Java programmers

Java is a highly versatile language that can be used in a wide range of areas, including core systems, games, web applications, and smartphone applications, but what will happen to it in the future? It will be useful if you can handle not only existing support operations, but also upstream processes and management. AI has yet to take over app development. Let’s also acquire various useful personal skills such as oracle and ruby.

Emergence of alternative languages

In recent years, Scala, Kotlin, etc. have appeared, and the presence of Java is fading. These new languages have less code than Java and can take advantage of many of the Java libraries. Therefore, it is possible that the demand for Java will decrease in the future.

decrease in income

As I explained above, I am concerned about the decrease in income. Prices are expected to fall due to oversupply. At the same time, it is also a concern that the number of projects has not increased much and is on the decline.

Server side demand

Many applications that run on the server side use Java. For this reason, Java is in high demand in various companies when used on the server side. Having framework skills will be a huge advantage.

most used around the world

Java is the most used language around the world. Java is a proven language that has been used for many developments around the world, so it will not disappear suddenly. Although the number of engineers is saturated, the demand in the business world will never disappear. Java has been applied and used for a long time, from major companies to venture companies, compared to COBOL, PHP, etc.

Maintenance matters

Many systems have already been written in Java. This means that there is also the work of operating and maintaining the system. Even if the number of new projects decreases, maintenance and development will not disappear in the future. There are many systems built with Java, and there are many jobs available.

Demand for Java programmers

Even though there are concerns as mentioned above, there is still a large number of projects available at the moment, so it is quite possible to become a freelancer and work independently. If you want to become independent with Java, the key point is to find the best conditions possible, as the unit price is likely to drop. Please register with as many agents as possible and start looking for jobs. Compared to others, you can search for jobs for free in a large market, and there are many services available. The fields of software development are very wide, such as Android apps, large corporate financial institutions, and smartphones.

The number of job openings is overwhelmingly large.

Nowadays, the demand for Java is not going away. This is because Java was still overwhelmingly dominant in the IT industry in the 2000s. Although new languages such as Python are appearing one after another, it is still true that the number of job openings for Java is overwhelmingly higher. There are very few people who are having trouble looking for a job. If you grasp the important points from the requirements posted in the first job posting, learn effectively from books, etc., and grow, there are many opportunities to become a full-time employee, so you can consider it.

Developed on many systems

Java is already used in many development projects. Therefore, it is more reliable than other languages, and even now Java is often used for new development. I don’t think this trend will change that easily. There is also a large amount of maintenance work for systems developed with Java, so it is unlikely that the demand will disappear for some time. If you understand things like Windows, Linux, and iOS, you will be able to move forward with more projects depending on your goals.

large scale development

Java is object-oriented, making it suitable for large-scale development tasks. Java usage and implementation rates are very high in large-scale development projects. Unless an object-oriented language that surpasses Java emerges, I think Java will continue to be the language of choice for large-scale development in Japan. There are a variety of responsibilities, from project manager to coding and testing, so there are many opportunities to gain experience in different positions. There are many career options.
