These are the three reasons Java remains relevant, and three more reasons Java is becoming obsolete. What does this all mean for Java developers?
"Should Java become your first language?"
This question is one you may ask yourself whether you're a novice or an experienced Java developer. Java is becoming less popular and Java feels older.
I can't tell you whether Java programming should be taught by 2022. Java is important, but Java may be slowly dying.

Why Java is Still Relevant
Let's start with the many benefits Java offers in modern programming.
1. Massive Java codebases
It is a great reason to learn Java 2022. There has been so much Java code written and someone will be responsible for maintaining that code for many years.
Employers looking for Java programmers will find you more relevant if you learn Java. Java codebases such as the ones created in FORTRAN or COBOL many decades ago aren't likely to disappear. Java programmers are also highly sought after.

It is a great reason to learn Java 2022. There has been so much Java code written and someone will be responsible for maintaining that code for many years.
Employers looking for Java programmers will find you more relevant if you learn Java. Java codebases such as the ones created in FORTRAN or COBOL many decades ago are not going anywhere. Java programmers are also highly sought after.
2. Java can be used wherever you are
Java's platform independence was one reason it became so popular during the 1990s. Java programs can be run on Linux or Windows without having to change your code.
Java is an excellent choice for general-purpose programming. Although newer languages (like Go) are also relatively platform-independent, Java arguably remains the gold standard of programming languages that let you write your code once and run it anywhere.
3. Java is very modular
Java's emphasis upon modularity is another reason it was so popular decades ago. Java wasn't the first object-oriented language, but it's likely it was the most widely used.
Java's modularity and object-oriented architecture are strong selling points. Java is a popular choice for developers who want to reuse code across a company. Java lets you borrow code from other projects to create new apps more quickly.

However, you can make a strong argument that Java is less worth learning.
1. Java is losing its popularity
Java is slowly falling out of favor. Java was the most popular language for many years. It is now the third most used language. Java has become less popular in recent years.
Java won't disappear, however. Businesses around the world will continue to need Java programmers for decades, in order to maintain their legacy codebases.
Java is not the best language to use if you want to create new things or maintain existing ones.
2. Platform independence will be less important in 2022
Java's platform independence today is perhaps less important than it was 10-20 years ago.
Software-defined environments are the norm. You can run your application wherever you want, using virtual machines, containers, and cloud services. This means you don't have to change your code to make your app work as you want. You can instead modify the hosting environment. This doesn't mean application portability isn't important anymore. Java is less important than ever.
3. Java is not an easy language
Java is easy to learn.
Java code is simple and easy to use. Java code is more complicated and takes longer to write. Java is less user-friendly than Python languages because it must be compiled.
Java is an excellent language for college students learning to code. Java is not the right choice for professionals who need to quickly create simple, elegant code.
Conclusion
Java is unlikely to disappear soon. Java is too deeply embedded in programming culture, codebases, and programming practices to disappear.
Java isn’t the popular universal programming language that it was in the 2000s and 1990s. Java's golden age has ended. If you don't have specific goals for Java, it doesn't make sense to learn Java now.
