If someone asks you what are 5 technologies you know, Java is probably one of them. In fact, taking into account the 2019 Stack Overflow Developer Survey, over 53% of developers named Java their most popular language.
This is a set of tools that includes almost everything you need for Java development. It, therefore, consists of the elements listed below:
1. Java Development Kit (JDK)
JDK is the first thing a developer downloads to start developing Java. The JDK itself is a software package that includes compilers, documentation, utilities, and a Java Runtime Environment (JRE).
2. Java Runtime Environment
A layer of software that runs on a computer’s operating system. It basically contains the Java Virtual Machine (JVM) and the standard Java class library. The JRE merges the code with the necessary libraries, then starts the JVM (a tool that converts Java bytecode into machine code) to run the code. It also ensures that dependencies are available for the Java programs that you develop.
3. Integrated Development Environment (IDE)
The application allows the user to run, edit, and compile code. Many IDEs have features like syntax highlighting and code completion that makes the coding process easier. If we take the top 3 IDEs that Java developers love, they are IntelliJ IDEA, Eclipse, and NetBeans
Advantages of Java
Java is a never-replaceable language in Android development for a very simple reason: Java was the only official programming language for Android development. there are still a wide variety of options for web development using Java today.

Despite stiff competition from other technologies, Java does not lag behind and still has some advantages to offer that could lead someone to vote for their favorites.
1. A High-level Language
This term implies that a programming language is very similar to human language, not mechanical language. Hence, it should be simple and easy to write, read, and maintain.
2. Stability
Solutions created with Java are considered stable. This is in part because a new version of Java is released every day, with new features and enhanced functionality.
3. It’s Object-Oriented
Since Java is part of object-oriented programming, it enables a developer to write typical programs and reuse code. We can therefore declare classes, generate objects within classes, edit and maintain the interaction between two objects.
4. Maintenance is Quite Cheap
The work of a Java program is not based on a single hardware infrastructure, so the server can run on any computer. Result: maintenance is cheap.
5. Security
Java was the first technology to have security as an integral part of the design. The JVM has a special identifier that recognizes the bytecode and checks it before it is executed.
6. Multithreading
Internally, a Java program can perform several tasks at the same time.
7. Distributed Computing
It is a method in which several computers work together on a network. This is definitely a benefit as apps can be developed over networks that can add functionality and data to the app.
8. It is Portable (platform-independent)
Portability means that a developer-only has to write code once and the program can be started on any platform. The only requirement is that this platform supports JVM.
9. Robust
Java is considered to be the most reliable and powerful language. Your compilers can detect all kinds of errors in your code. In addition, Java has features like exception handling and garbage collection that also prove that Java can be trusted.
Disadvantages of Java
Unfortunately, like any other technology, Java also has a number of disadvantages. The main disadvantages of Java are as follows:
1. Java’s Performance
If we compare Java programs with those written in or C ++ and which are natively compiled, it is easy to see that they are much slower.
2. Its Memory
In Java, memory is managed by the garbage collector. Every time the garbage collector works, it degrades the performance of the application. The main reason for this is that the garbage collector will only work when all other threads are down.
3. Cost of the Business License
Starting in 2019, Oracle expects users to pay for Java Standard Edition 8 when used for purposes such as business, commerce, and manufacturing. Therefore, if you need updates and bug fixes, you will be billed based on the number of users you have or your CPU. It really hurts when you start counting the new cost.
4. The Look is Not Native (desktop) (office)
Programmers use a variety of tools for each language to create the graphical user interface or GUI for short. Of course, one shouldn’t forget Android Studio, which was originally designed for Android mobile development, to make apps look native.
Once the discussion of the desktop program’s user interface begins, Java will definitely be left behind and you will have to do some very thorough research to find a suitable tool for creating your graphical user interface.
5. Java’s verbosity makes the code quite complicated
Java implies that you have to use a lot of words because it is very similar to the natural language of humans. Developers almost literally write their commands and thoughts, so the code is considerably huge (especially compared to Python).
