Development With Java: Pros and Cons

Updated: Dec 7, 2021

What is the main principle of the tech stack choosing? - That's right: choose reliability.

We in JEVERA believe that reliability is the middle name of Java. So, let us prove that Java programming is almost always suitable for business.

But to be fair, let's consider why Java is suitable for enterprise app development and why sometimes it's better to choose some other languages.

Advantages And Disadvantages Of Java

Java still allows an unimaginable enterprise and other application development: irreplaceable Big Data products, hardy moon rovers, or ultra-fast electric cars. At least 8 million Java developers believe that the future belongs to this language.

"However, when Java is promoted as the primary programming language, its flaws and limitations become serious." Bjarne Stroustrup, Founder of C++.

Let's form an unbiased opinion considering the key advantages and disadvantages of Java.

7 Benefits Of Java

1) Java is object-oriented

If a developer can define both the type and structure of data, it is easier for him to manage the created objects and build connections between them. This approach, unlike procedural programming, accelerates the development cycle.

2) Java is easy to learn

Indeed, it is not as easy as Python but also not as complicated as C++. Java syntax is so close to English and intuitive. Because of it, developers can write code that is clear to any beginner.

3) Java is safe

Mainly because here you can use a Secure Management service. It allows data isolation in a multi-user environment and the provision of customized limited access. Therefore, Java is often used for IT, government, finance, and legal software development.

Moreover, Java boasts a lack of pointers, storing the addresses of other values. This feature minimizes the risk of unauthorized access and helps in internal corporate investigations.

4) Java runs everywhere

James Gosling, Founder of Java, once said: "From the point of view of the people who are using the platform, one of the most valuable things about Java is the consistency, the interoperability."

It's holy truth. Any platform containing JVM can reproduce a Java application's bytecode. Let's say, if you designed a solution on Linux, it could work on Windows without any issues.

5) Java for relevance

Did you know that, in 2020, 74% of companies planned to shift to the WFH mode? Java creators have taken care of the convenience of app end-users in advance. The language allows fast, secure data and object exchange between several gadgets. It makes remote collaboration even more convenient.

Moreover, Java will probably never cease to be modern due to the constant release of new versions. Recently, Oracle has been doing it twice a year. However, it does not change the fact that in 2021, 69% of respondents are still actively developing in Java 8.

6) Java takes care of memory

The language automatically manages memory and removes unused code elements, preventing garbage accumulation. It allows developers to focus on coding rather than manual cleaning. On the other hand, if you don't want the system to delete a crucial object waiting in the wings - use custom intelligent settings.

7) "Java" means "easy maintenance"

It's the reason why Java is used for complex enterprise app development. It's easy to navigate Java code, testing or maintaining products. Due to it, a programmer can find and update/fix the required piece of code in a matter of hours. For engineers, it is a convenience. For business, it is a guarantee of flexibility.

Java Disadvantages

1) Java is slow

Slowness is the biggest drawback of Java. Its performance level is not high because of:

  • the necessity to pass bytecode through the JVM;

  • automatic garbage cleaning;

  • intermittent lack of memory

Of course, Oracle tries to eliminate such issues in every possible way. Anyway, even in 2021, engineers are worried about all the same Java slow work.

2) Java is full of contradictions

Remember, we're calling clear Java's syntax one of its significant advantages. But, there are two sides to the coin. Unfortunately, Java requires a lot of syntax character usage. It makes the code overloaded.

3) Java, where is the backup?

Unfortunately, for all its merits, Java does not please users with a backup feature. This way, you are not insured against the irretrievable loss of code in the case of the system's failure.

Java Programming: Disadvantages

Bottom Line

It's early to plan a Java's funeral as long as it has more pros than cons. Of course, now, the technology world operates with many younger programming languages ​​that are somewhat superior to Java. But the strength of the latter is in its versatility and large community.

Developing in Java, you will never get stuck. The answers to all the questions already exist.
