I think without Javadoc documentation, Java wouldn't be as popular, and it's one of the main reasons, Why I believe Java is the best programming language.Not everyone has the time and intention to look at the code to learn what a method does or how to use a class. Javadoc made learning easy and provide an excellent reference while coding in Java. With the advent of IDEs like Eclipse and IntelliJ IDEA, you don't even need to look at Javadoc explicitly in the browser, but you can get all the information in your IDE window itself.9. Java is Platform IndependentIn the 1990s, this was the main reason for Java's popularity. The idea of platform independence is great, and Java's tagline "write once run anywhere," and acronym "WORA" were enticing enough to attract lots of new development in Java.This is still one of the reasons for Java being the best programming language, most Java applications are developed in the Windows environment and run on the Linux platform.10. Java is EverywhereYes, Java is everywhere, it's on the desktop, it's on mobile, it's on the card, almost everywhere and so are Java programmers. I think Java programmers outnumber any other programming language professional.Though I don't have any data to back this up, it's based on experience. This vast availability of Java programmers is another reason why organizations prefer to choose Java for new development than any other programming language.Having said that, programming is a massive field, and if you look at C and UNIX, which are still surviving and even stronger enough to live another 20 years, Java also falls in the same league.Though there are a lot of talks about functional programming, Scala, and other JVM languages like Kotlin and Groovy, they need to go a long way to match the community, resources, and popularity of Java.Also, OOP is one of the best programming paradigms, and as long as it will be there, Java will remain solid.How to Learn Java Programming from Scratch in 2025?Now, if you decide to learn Java programming, here are a couple of resources to take a look at. I personally suggest joining an online course to start with and then picking a book, because they are almost always well written by authorities in the subject matter and catered for beginners.To start with, I recommend joining The Complete Java Master Class at Udemy. You can buy this course for just under $10 on Udemy's flash sale, which they run, I think every month.This course is very comprehensive and up-to-date and covers both Java SE 8 and other latest Java features.

Often confused with JavaScript, Java is a popular programming language. It is considered general purpose, meaning that Java can be used in a variety of different programming situations. It is this versatility that has led to Jaava being so widely used as a computer language, alongside Python and the aforementioned JavaScript.If you are into programming, then you likely have some experience with Java. But have you ever wondered who created this language? If so, you’ve come to the right place! We have all the information that you need to know about the creation of Java.Who Created Java?Who is James Gosling?What is Java?Why is Java so Popular?Ease of UseAdaptable and VersatileThere are Tons of UsersIt’s Object-OrientedPortabilityWhat Companies Use Java?Frequently Asked QuestionsWhat is the Difference Between Java and JavaScript?Why Was Java Invented?Is Java Hard to Learn?Final ThoughtsAdvertising links are marked with *. We receive a small commission on sales, nothing changes for you.Java was made by James Gosling. It was first released in January 1996. Because of his creation of the programming language, Gosling has been dubbed “Dr. Java” by its users.The origin of the language dates back to 1990, when it started as a project at a technology company called Sun Microsystems. While Gosling led the project, a group of researchers helped him to develop Java.During the period before its creation, Java went through several names. This includes the Stealth Project, Oak, and Green Project. The name Java was eventually chosen as an allusion to Java coffee, which originates from Indonesia.Who is James Gosling?Born in 1955, James Gosling is a computer scientist from Canada. He is the creator of Java. Prior to his creation of Java, Gosling spent lots of time studying computer science. Having worked with the University of Calgary as a high school student, Gosling attended the university where he obtained a Bachelor of Science in computer science. After this, Gosling earned a Master’s degree and P.H.D. in computer science from Carnegie Mellon University. After this, Gosling joined Sun Microsystems, which led to him formulating Java.This impressive creation has garnered Gosling much acclaim and respect. For example, in 2004 he was chosen as a member of the National Academy of Engineering. Moreover, in 2007, he was given the Order of Canada. This is the second highest form of honor in Canada that can be given to civilians.

It is. If you have a steep learning curve, it would be difficult to get productive in a short span of time, which is the case with most professional projects.Java has fluent English like syntax with minimum magic characters like Generics angle brackets, which makes it easy to read Java programs and learn quickly.Once a programmer is familiar with the initial hurdles with installing JDK and setting up PATH and understands How Classpath works, it's pretty easy to write a program in Java.2. Java is an Object-Oriented Programming LanguageAnother reason, which made Java popular is that it's an Object Oriented Programming language. Developing an OOP application is much easier, and it also helps to keep the system modular, flexible, and extensible.Once you have knowledge of crucial OOP concepts like Abstraction, Encapsulation, Polymorphism, and Inheritance, you can use all those with Java. Java itself embodies many best practices and design patterns in its library.Java is one of the few close to 100% OOP programming languages. Java also promotes the use of SOLID and Object-oriented design principles in the form of open source projects like Spring, which make sure your object dependency is managed well by using the Dependency Injection principle.3. Java has Rich APIOne more reason for the Java programming language's huge success is its Rich API, and most importantly, it's highly visible because it comes with Java installation.When I first started Java programming, I used to code Applets, and those days Applets provides excellent animation capability, which amazes new programmers like us, who are used to code in Turbo C++ editor.Java provides API for I/O, networking, utilities, XML parsing, database connection, and almost everything. Whatever is left is covered by open source libraries like Apache Commons, Google Guava, Jackson, Gson, Apache POI, and others.You can further see my post on 20 essential open source libraries for Java programmers to learn more about useful libraries Java developers should know. 4. Powerful development tools like Eclipse, NetbeansBelieve it or not, Eclipse and Netbeans have played a huge role in making Java one of the best programming languages. Coding in IDE is a pleasure, especially if you have coded in DOS Editor or Notepad.They not only help in code completion but also provides a powerful debugging capability, which is essential for real-world development. Integrated Development Environment (IDE) made Java development much more comfortable, faster, and fluent. It's easy to search, refactor, and read code using IDEs.Apart from IDE, the Java platform also has several other tools like Maven and ANT for building Java applications, Jenkins for Continuous Integration and delivery, decompilers, JConsole, Visual VM for monitoring Heap usage, etc.You can also see my post 10 Essential Tools for Java Programmers to learn more
