10 reasons to learn Java programming language and why Java is good

Java is a popular programming language. This is proven practically during the past 20 years.

Two decades is not a short time for any programming language, and Java has confirmed its power every day. At times, Java has slowed down, but it has adapted well. Previously, with fundamental changes in Enum form, Generics, and autoboxing in Java 5, improved performance with Java 6, and Google's choice of Java language to develop Android applications, Java still held the position as Pioneering programming language.

Many students often ask me, "Which programming language is the best that we should learn, should I study Java …?". Yes, it depends on your best programming language definition, in terms of popularity, Java is clearly superior to any other language, even C, even though C already exists in nearly 41 years (1972). Considering job opportunities, Java once again scored points in all other languages. You can find countless job opportunities by learning the Java programming language, you can develop basic Java for server-side applications, Web applications, and enterprise applications, and even It is applicable for mobile application development based on Android platform. So, if you have not learned C and C ++ programming languages, and want to learn the first programming language, I recommend choosing Java. In this article, I will share the reasons why you should learn Java programming.

Here are 10 reasons I always tell anyone to ask me about learning Java, and whether Java is the best programming language in terms of job opportunities, application development and community support. copper.

1. Java is easy to learn

Many people will be surprised to see this as one of the top reasons to learn Java, or treat it as the best programming language, but that's true. If you learn fast, it will be very difficult to complete in a short time, which is an example of most professional projects. Java has a clear syntax with small annotations, for example Generics with curly braces that contain data types that make reading and learning Java programs easy and fast. Once the developer is familiar with the initial barriers such as installing JDK and setting up PATH and understanding the behavior of Classpath, they can write programs in Java very easily.

2. Java is an object-oriented programming language

Another reason Java is popular is because it is an object-oriented programming language. Developing OOPS (Object-Oriented Programming System) is much easier, and it also maintains system modules, flexible and expandable. Once you have knowledge of OOPS definitions such as abstraction, packaging, multitasking and inheritance, you can use them in Java. Java itself embodies many of the best thinking methods and designs in its libraries. Java is one of the few programming languages ​​that reaches nearly 100% OOPS. Java also promotes the use of SOLID principles (Single responsibility, Open-closed, Liskov substitution, Interface segregation and Dependency inversion – an object-oriented design) and object-oriented design in the form of open source projects like Spring , which makes sure that your dependency is well managed by using Injection Principles (a theory in software design).

3. The number of Java functions available (API functions) is very rich

Another reason that brings great success to the Java programming language is that it is much API. Most importantly, it is very easy to see, because it appears with Java installation. When I started Java programming, I wrote code for Applets and at that time Applet was a solution for great animation effects, which surprised the new programmers like us, who are using source code in Turbo C ++. Java provides APIs for I / O (data communication), networking, utilities, XML, parsing, database connectivity, and almost everything. The rest is contained in open source libraries such as Apache, Google Guava and some other programs.

4. Powerful development tools like Eclipse and Netbeans

You may not believe it, but Eclipse and Netbeans have played a huge role in making Java one of the best programming languages. Writing code in IDE is fun, especially if you've ever written code in DOS Editor or Notepad. They not only help complete code but also provide powerful error correction capabilities, which are necessary in a realistic programming environment. Integrated development environment (IDE) makes Java development easier, faster and more convenient. Search, reorganize code and read code using IDE. In addition to IDE, the Java platform also has some other tools such as Maven and ANT to translate and package Java applications, reverse code, JConsole, Visual VM to monitor Heap memory …

5. Rich open source library collection

Open source libraries ensure that Java can be used everywhere. Apache, Google, and other organizations have contributed a lot of large libraries, making Java easier, faster, and more cost-effective. There are structures like Spring, Struts, Maven that ensure Java development by the best software development method, promote the use of designs and support Java programmers to get the job done. I always recommend looking for a function to write in Google before writing your own code. That's a good opportunity because it's mostly written, tested and available for use.

6. Support the great community

Community is the greatest power of the Java programming language and this platform. No matter how good a language is, it will not exist without community support, help and knowledge sharing. Java has been very lucky, it has a lot of active forums, StackOverflow, open source organization and some groups of people who use Java to help each other. The community of senior Java programmers and even experts will help beginners. Java really promotes the acquisition of knowledge and contribution to support the community. Lots of developers, open source users, involved in building, upgrading open source code, testing, … Experts are free at many Java forums and StackOverflow. This great thing has brought confidence to Java programmers.

7. Java is free

Everyone likes free things, right? So, if a programmer wants to learn a programming language, or an organization wants to use a technology, cost is an important factor. Because Java is free from the beginning, you don't need to pay any cost to create Java applications. This also helps Java become a common skill in the developer community, and large organizations. The abundance of Java programmers is a great advantage, making it easy for organizations to choose Java for their development strategy.

8. Excellent document support – Javadocs

When I first saw Javadoc, I was surprised. That document contains a lot of information about the Java API. I think without Java Javoc documentation, Java wouldn't be popular, and that's one of the main reasons I think Java is the best programming language. Not everyone has the time and the intention to look at the code to learn how or how to use a class. Javadoc makes learning easy and provides a great reference while writing Java code. With the appearance of the IDE, you don't even need to see Javadoc explicitly in the browser and you can get all the information in your IDE window.

9. Java is an independent platform

In 1990, this was the main reason Java was popular. The idea of ​​platform independence is great, and Java's slogan "writing once and everywhere" is enticing enough to attract a lot of new developments in Java. This is still one of the reasons Java is the best programming language, most Java applications are developed in Windows environment and run on UNIX platforms.

10. Java is everywhere

Yes, Java is everywhere, on desktops, on mobile phones, on cards, almost everywhere, and so does Java programmers. I think the number of Java programmers goes far beyond the programmer of any other professional programming language. Although I don't have any data to clarify that statement, experience has shown me that. Large numbers of Java programmers are also a reason organizations want to choose Java for new developments than any other programming language.

It can be said that programming is a very wide field and if you look at C and UNIX, they are still alive and getting stronger, enough to live another 20 years, Java is not inferior. There are many discussions of functional programming, Scala and other JVM languages, but they need to go a long way to be compatible with the community, resources and popularity of Java. Unfortunately, object-oriented programming is also one of the best programming models, and as long as it exists, Java will remain solid.
