Why you should learn Java

In my opinion, learning Java is fundamental for becoming a software developer and understanding the big picture of this field, you can become a software developer without knowing Java but knowing about the language will allow you to learn easier, and faster new technologies. Java covers several concepts such as the OOP paradigm, automatic garbage collection, access modifiers, data structures, algorithms, distributed computing, and much more.

  • Java is popular
  • There are jobs for Java developers
  • Java has been everywhere
  • Java is used in real-world apps
  • Java has remained powerful
  • There are lots of Java tools for solving different problems and necessities
  • Java community is big and passionate
  • Java is still being updated
  • Many things more…

Facts about Java

Java is a programming language, designed to be concurrent, class-based, and object-oriented, as well as a computing platform. Java is high-level and designed to have as few implementation dependencies as possible.

A high-level programming language is a programming language that abstracts details of a computer. That is a programming language that enables a programmer to write programs that are more or less independent of a particular type of computer, they are closer to human languages and further from machine languages. In contrast, low-level languages are closer to machine language such as assembly language, these languages are closer to the hardware.

  • JVM memory
  • Execution engine
  • Native method interface and
  • Native method library


Computers and applications are expected to do more than one thing at a time. Software that can manage multiple tasks at a time is called concurrent software. Concurrency is also the ability of different units of a program to be executed out of order, or at the same time. This can significantly improve the execution speed of a program. Java supports this.

Class-based and object-oriented

Class-based programming is a style of OOP, where the inheritance mechanism (One child class can inherit behavior and properties from a parent class) occurs via defining classes of objects.


When we say that Java is designed to have as few implementation dependencies as possible, it means that Java modules are designed to have low interdependence. This is translated into a sign of having a well-structured system, and a good design, that is a system with high readability and maintainability.

Java is general-purpose

Languages that are designed to suit a specific purpose are called domain-specific languages.

  • Enterprise applications
  • Scientific applications
  • Gaming applications
  • Mobile applications
  • Desktop GUI applications

More features of Java

  • Scalability
  • Cross-platform
  • Memory-management
  • Multi-threading


As we saw, Java is everywhere, it touches every software development field and is used by popular platforms that you might often use. So if you are wondering if you should learn Java as a developer, the answer is yes.
