Why Java is Object-Oriented?
The aspect which makes Java one of the more attractive languages is Java, which is an Object-Oriented Programming (OOP) language, in its essence. It follows an object-oriented programming (OOP) approach, which helps in maintaining our code since an object embeds data and its behaviour. Java strongly supports the concepts of Object-Oriented Programming, for this reason, Java is called as pure OO language. The syntax of Java is heavily influenced by C++ and C. Unlike C++, which combined the syntax for structural, generic, object-oriented programming, Java was built almost solely as an object-oriented language.
Java is designed to have the appearance and feel of a C++ programming language, yet is easy to use and mandates an object-oriented programming model. Java is part of the family of languages, heavily influenced by C++ (as well as C#), so learning Java offers huge advantages over learning those other two languages. Java is a simpler language that you can pick up very quickly, making programming much easier and quicker. One of the primary ways developers ensure they are writing robust, bug-free Java code is to take advantage of the many powerful development tools associated with the language.
Why Java is Secure?
The main goal behind creating Java programming language was to make it a portable, easy, and secure programming language. Java was specially designed to allow Java to be used in any computer, whether running Windows, Linux, Mac, UNIX, or any of the other operating systems. Java is considered very straightforward; however, it comes with a library of classes that provide utility functions commonly used, which are something most Java programs cannot function without. Java is the most popular programming language for Android smartphone apps, as well as one of the most preferred languages to develop for edge devices and IoT.
Platform independent — unlike many other programming languages, including C and C++, when you compile a Java programming language, you do not compile to platform-specific machines, but to bytecode that is platform-independent. Java is a general-purpose programming language designed for allowing application developers to write once, run anywhere (WORA), which means compiled Java code can be executed on all platforms supporting Java, without a recompilation. It is widely used in the Software, Web, Mobile App development, apart from this, it is also used in Big Data analytics and server-side technologies. Java is widely used to develop Java applications on Laptops, Data Centers, Gaming Consoles, Scientific Supercomputers, Mobile Phones, etc.
The most important characteristic of Java is that it provides platform independence, leading to portability capability, ultimately becoming its greatest strength. The principles of building java are easy, reliable, secure, fast, portable, threaded, interpretive, dynamic, etc. As per company’s stated mission, the JavaSoft product offerings comprised of a basic Java platform, comprising the Virtual Machine, the Java Language, and Java APIs (application programming interfaces).
Why Java is Robust?
Java is a reliable programming language as it provides features such as automatic garbage collection and dynamic memory allocation. Java is robust because it is capable of managing runtime errors, supports automatic garbage collection and exception handling, and it avoids the notion of explicit pointers. Java is a robust language that is able to handle run-time errors, since Java checks code at the compile-time as well as at the run-time.
Java makes efforts to remove code which is prone to errors, by emphasizing compile-time checking of errors as well as run-time checks. Java is a type-checking-heavy language that has strong type checking at both the compilation time and runtime, allowing us to develop error-free applications and programs. Java is easy as java makes coding easier for programmer by avoiding some features of C and C++. Java is one of the most widely used programming languages, allowing development of different types of applications, which can be run on the same machine.

Why we use Java?
Java supports major features of object-oriented programming such as Encapsulation, Abstractions, and Inheritance. This language has removed a lot of complex, seldom-used features, such as explicit pointers, operator overloading, and so on.
Java is architecture-neutral, as no implementation-dependent features are present, such as fixed primitive type sizes. Java is considered to be a strong, reliable programming language as it has robust memory management, and since Java does not use pointers of any kind, which circumvents security dilemmas.
The language is considered very easy; however, it comes with library of classes that offers utility functions commonly used which are impossible for most of the Java programs not to run. Java continues to be one of the most popular programming languages among developers and technology companies due to its unique features. Java has been an extremely popular and useful programming language due to its great features, which have played an extremely major role in contributing to this languages popularity. Now, we know which features have made Java a popular and useful programming language among Programmers, Software Developers, and Data Science professionals.
All of these outstanding features make Java a powerful programming language, and that is the reason every learner wants to learn Java. Other factors which make Java a highly robust language include the fact that Java eases a programmer to use efficient type checking & exception handling mechanisms compared to other languages. It is developed such that it puts in lot of efforts in inspecting errors at an early stage, which is the reason that the java compilers are capable to detect even those errors that are not easily detected by other programming languages.
As Java is platform-independent language, therefore, Java is not specific to any CPU or OS. It means that the java language is used to develop distributed applications where resources are shared between more than one clients. Java is made up of 50 keywords, but Java API has thousands of classes with tens of thousands of methods that you can use in your programs.
The Importance of Java
Since the development of the Java programming language, it has seen immense popularity and remains one of the most liked programming languages in terms of software development. Here are some amazing factors that would give you a clear understanding of why Java has millions of fans in the programming world.
- First of all, Java is platform independent. What does this mean? This simply explains that machines or devices with JRE (Java Runtime Environment) installed on them can run Java code effectively. There’s a globally acknowledged phrase that is used for Java: Write Once, Run Anywhere. This makes the language versatile and compatible across other OSs, such as Windows, Linux, MacOS, etc. This makes the code-portability super easy and fast, making the development process way smoother and reducing time and resources.
- The second one is robustness and reliability. This property of Java draws the attention of developers. Along with this, Java provides developers with strong memory management, exception handling, etc. It has extensive libraries that support developers in developing stable and secure applications.
- The third one is well-known and is a significant feature of Java, and that is the non-OOP concept. This amazing property is like “icing on the cake”. This concept encourages code reusability and scalability, which are important to creating robust applications.
- The fourth is having a huge Java community. The active community plays a key role in the road to its success globally. The active Java community offers plenty of resources and frameworks that streamline software development. Java has a number of frameworks like Spring, Hibernate, and Struts that elevate the productivity and efficiency of the software developer.
- The fifth one is Java’s flexibility and versatility. With this feature, the Java programming language becomes the best choice to develop high-quality enterprise-level applications. Along with it, Java seems appropriate for web applications as well as mobile apps.
