Therefore, in this article, we will be covering:
What is Java?
Java is a cross-platform, class-based, general-purpose programming language used to build different and complex applications like web applications, mobile applications, big data technologies, etc.. It incorporates object-oriented programming concepts like inheritance, encapsulation, abstraction, etc., to make the language secure and reliable.
It is a computing platform that consolidates a compiler, execution engine, computer software, set of libraries and, so much more for developing, running Java Applications and programs.
Another important part of Java is JVM i.e., the Java Virtual Machine. JVM is a machine that allows Java to convert byte-code into any machine code. Now, byte-code is an intermediate code translated from the source code. This code, unlike the machine code, runs on the JVM to be interpreted by different machines Java applications run on like Linux, macOS, Windows, etc.
JVM ensures Java supports the feature of Write once Run Anywhere by giving adaptability for cross-platforms.
All these different platforms have distinct characteristics and features that help programmers build desktop, mobile web applications. Some platforms are suitable for developing API’s for desktop applications or some work well for Graphic User-interface Development, one might be beneficial for its high performance.
The pivotal aim for the applications is to assist programmers in an easy, fast, and secure development and execution process.
- Interactive Forms
- Auto Updates
- Autocomplete text suggestions
- Animation graphics
and so much more.
- Adding interactive, functional elements to the web pages
- Developing web-based games
- Creating Mobile Applications
- Back-end or server-side development
Features of Java
- Easy and Simple to Understand
Java is known for its simplicity as it comes with a code that has a familiar base from languages like C and C++ but minus the complexities of those languages. Complexities like Storage classes, operator overloading, etc.
Java is a platform-independent programming language. This means that Java code can run on any machine, any platform, any operating system.
It is possible because of Java Virtual Machine and Byte Code.
Byte code is an intermediate code, a converted code from the source code which runs on JVM. JVM is software that allows executing ByteCode on different platforms and Operating Systems.
Java programming language supports all the object-oriented programming features and concepts like Encapsulation, Abstraction, Inheritance, etc. These OOP concepts provide many advantages to the language like security, prevent data redundancy, easy troubleshooting and many more.
- Compiled and Interpreted
Many programming languages have either the advantage of compiling or interpreting the code.
Java, on the other hand, is a combination of both advantages.
With Java, you can compile the source code into ByteCode and interpret it on JVM to make it executable on any machine or platform.
- Secure and Reliable
Java as a programming language includes many tools, features, etc. that makes it a secure and reliable language for programmers and developers. It provides secure communication, public key infrastructure, authentication, cryptography and so much more for providing a secure and reliable framework for the developers.
- Front-end Scripting Language
- Prototype-Based Language
- Default Parameters
- User’s Input
(the function of handling different instructions at the same time)
|Suitability||Java can be used for several types of application development including: • Mobile application development|
• Cloud-based Applications

|Key Features||• Extensive Libraries|
• Simple and Easy to Learn
• Powerful frameworks
• Great for front-end development
|Companies Using||Netflix, Google, Airbnb, etc.||Paypal, Uber, Microsoft, etc.|
Advantages of Java
- WORA (Write Once Run Anywhere)
Java’ portability features of compilation and interpretation make it compatible to write once and can run anywhere. You just need to write the source code that will be converted to a Byte code on JVM for interpretation on any machine or OS.
- Robust and Secure
Java’s features make it one of the secured platforms for developing and running applications. For example, it does not support explicit pointers (a function of providing memory addresses to different values) or robust security measures while defining classes, etc., to minimize unauthorized access and cyberattacks.
- Automatic Garbage Collection
Java, with the feature of automated garbage collection, does not let unused, idle objects take up unnecessary space. It cleans up automatically objects that are nowhere to be used in programs.
Java ensures multi-threading. It means that Java supports the performance of simultaneous tasks. Thread here is a unit of a process and Java can run multiple threads at the same time.
Disadvantages of Java
Java is not as rapid as its native or peers languages like C++ and C. It significantly gives a slow performance because of the additional tasks of compilation and interpretation. Java also has high memory consumption that put a heavy load on the CPU and slows down the efficiency of the language.
- Memory Management
Auto Garbage Collection is both a benefit and drawback for Java. Yes, it surely automatically collects unnecessary and unused objects. However, it puts a heavy load on the processor and in addition, put a hold on the working of all the other threads as well. It increases the time to complete tasks.
Another significant drawback of Java is its lack of ability to back up data. There are robust features for storing and collecting data but not as such a strong facility that backs up data.
- Look and Feel
Java provides several frameworks and GUI builders for developing the user interface for applications and web pages. But, they are not suitable for building high-scaled, complex user interfaces. Frameworks like JavaFX, Swing, etc., do not provide much complexity and functionality for front-side development.
- Front-end security
- Browser Support
- Time Consumption
The question of the article is here. After a thorough reading of the article, it is evident to say that no one language is superior to another.
Java, on the other hand, is a standalone language that is fast, secure, and reliable for server-side development. Programmers use it for its extensive and rich libraries, efficiency and robust security features for creating mobile applications, desktop applications, gaming and web-based applications, and so much more.
Therefore, the choice comes down to the programmer or developer. It is up to you, your project and your requirements, what language you will prefer.
Yes, as there is no connection between the two. Both are different types of languages. JavScript is used mainly for front-end development like using for web-based applications or GUI desktop applications.
Java is used for server-side or backend development for desktop, mobile, web-based, gaming applications.
