Java vs Kotlin | Kotlin vs Java | Which should you have to use - Infocenter

  Hey guys, welcome to Infocenter. Java has been around for more than two decades, and that might be one of the reasons for why it has become a go-to programming language when it comes to choosing the Android development. But ever since Google announced Kotlin as the official programming language for the Android development at Google, one of the Android developers or even professional Android developers are in a constant dilemma of choosing between Java and Kotlin. This debate of Java versus Kotlin has been long overdue. So, keeping that in mind, we'll talk about the same, that is, Java versus Kotlin. So guys, before we proceed further, do subscribe to Infocenter's Website so that you never miss out on our next upcoming article.

    Let us start off by looking into the agenda for this article. First and foremost, we'll start the session by getting a proper introduction to both Java and Kotlin, and after that, we'll discuss all the parameters on the basis of which we'll make the comparison on Java and Kotlin. We'll also have a look at the percentage switching from Java to Kotlin and vice versa. Then we'll also look into the job trends in both the technologies. Finally, we'll conclude the session by deciding which one is better: Java or Kotlin. Guys, we'll also have a short quiz based on the article. Make sure to put down your answers in the comment section below. If you're looking for the courses in the trending technologies, do visit Infocenter023.blogspot.com So guys, without any further ado, let's get started. 

What exactly is Java ? 

     So guys, we all know that Java is one of the widely used programming language explicitly designed for use in the distributed environment of the Internet. It is a high-level programming language which are interpreted by JVM. Java also supports multi-platform and can run on different platforms including Macintosh, Windows, and UNIX computers. 

What is Kotlin ?

    Kotlin was developed in 2011 by the programmers of a software development company called Jet Brains in Russia and was then augmented by several open-source developers. Kotlin gives developers the features they ask for. So Kotlin is a general purpose, open-source statistically typed, pragmatic, or we can say practical rather than theoretical programming language for the JVM and Android that combines object-oriented and functional programming features. Now, we will see some of the pros and cons of both languages. So, let's move forward. First and foremost, we will discuss about Java. After that, we will see what Kotlin has. 

Java 

Pros of Java :-

    there are many advantages of Java that clearly represents its recognition among the developers' community and enterprises. Now, we will see one by one what makes us fascinate to learn Java. So, it is easy to understand and learn, and also it is easier to execute which run code in a browser or in a virtual machine. It provides open-source platform and up-to-date information and feature-rich programming language. It has the ability to assemble the large projects precisely with the help of modern tools. It also helps in wide community support that keeps Java up-to-date. We are all aware that it is owned by Oracle Corporation that is dedicated to making it stronger. Android it self depends upon Java language, and also there is a flexibility for cross-platform app development. It also guarantees the automatic and effective memory management which makes it portable to use on a range of devices from large networks to the lowest PCS. 

cons of Java :-

    Some of the cons that make Java not a prominent language for developing are: Java is slow. Java is comparatively slower than the other languages, one of the problems of Java which always annoys a programmer. So this is one of the biggest drawback of Java programming language. So, Java makes memory space and it takes more memory space than other native programming languages like C and C++. This problem hasn't been over come by the Java developer as of now, so language-limited latency-critical tuning. If you have to spare every second, then Java is not the best choice and instead use some other language in such scenarios. Java's architecture code is inefficient. So guys, Java's ability for producing portable architectural code is desirable. The method used to create this code is inefficient. So, last but not the least, it doesn't guarantee the backup. So, there is no backup. It is mainly for storage and less efficient for data backup. So, Java loses its value and prestige in such cases guys. This is also a drawback that affects Java's rating

Kotlin

 So guys basically it seems like Kotlin has been loved by many developers, or I would say mobile developers. Here's a list of Kotlin's most prominent benefits. 

 Pros of Kotlin :-

    It increases team efficiency being rather than clear and compact, the language allows increasing the efficiency. More work can be done as it takes less time, and few lines to write and deploy working code. So, next is it compiles with existing Java code. So, Kotlin is positioned as 100% Java interoperable programming language. It is consistent with Java and all related tools and frameworks which makes it possible to switch to Kotlin step-by-step. It is also easily maintainable because Kotlin is supported by a vast majority of IDs including android studio and other SDK tools. This helps in increasing the developer's productivity, as they can continue to work with the toolkit they are used to. Isn't it. So, everyone looks for less bugs, right. Here's our last but not the least advantage, that is, the Kotlin is less buggy. Kotlin offers a much more clear and compact code base that makes the code in production more stable and consistent. Bugs get detected at compile time, so developers can fix errors before runtime, isn't that cool! So guys, we have discussed about the advantages of Kotlin. Now, we are moving forward with its drawbacks. 

 cons of Kotlin :-

    First and foremost is that it has limited learning resources as it is a small and a new community which was originated in 2011. Therefore, there are only a few experienced people to ask and a few tools to use to pick up some tricks. It may become a challenge to switch from Java to Kotlin from a team. So, finding Kotlin developers seem difficult in Java developers. So sometimes compilation is slower as compared to Java. Now, we will discuss the major differences between both of them. So, no doubt, Java ranks as one of the most widely used programming language.

The Establishment :-

    Java was being developed in 1991, and it was a relatively new programming language. At that time, James Gosling from Sun Micro system and his team began designing the first version of java aimed at programming home appliances which are controlled by a variety of, you know, computer processors. In 1994, he realized that such a language would be ideal for use with web browsers, and Java's connection to the Internet began. So, Java was launched in 23 January 1996 which was initially developed by James Gosling at Sun Micro systems which is now a subsidiary of Oracle Corporation and was being released in 1995. Before 2017, Android app developers almost exclusively used Java 6 programming languages with support for their later edition. Java 6 was introduced in 2006, two years before the release of Android devices. In 2011, the company introduced Kotlin language, but few Android developers started using it. Although Kotlin was production-ready, the language was not stable. At Google i/o 2017, Google announced that Android will support Kotlin as a first-class programming language from now on, which was then launched in 2017. So, Kotlin is a statistically tied modern programming language that runs on a Java Virtual Machine by compiling Kotlin code into Java bytecode. It can also be compiled to JavaScript source code; isn't that interesting guys. 

The compilation speed for Java and Kotlin :-

    Java is a verbose language. You need to write a lengthy code that usually contains error and bugs also. So, it's that simple. Kotlin uses developer-friendly coding structures and norms that are easy to understand and use. In case of longer code compilation, Kotlin is preferred over Java. So guys, this seems quite obvious when you have a larger application or a bunch of files to be executed. So, Java is somewhat less considered in terms of speed. 

 The Lines of Code :-

    compared to Java, Kotlin has less lines of code which makes it safe, concise, with a lean text. So, Kotlin also offers null-safety where it avoids null pointer exception. If you try to assign or return null to a variable or function, respectively, then it won't compile. Now let us consider the example of a 'hello world' code. So, in case of Java, if you see on your screen, this is the code for Java, but in case of Kotlin, if you see, the code goes like this. So, when you consider the above example from developers' perspective, you will be able to understand why Kotlin is loved by developers around the world. It is concise, effective, and faster compared to Java. Moreover, there will be less chance of errors and bugs resulting in cost and time reduction. 

The Interoperability :-

interoperability is Kotlin's core purpose. from the beginning, the project's intention has been to use existing knowledge and expertise to make every library available to Kotlin programmers. So, developers can simply write modules in Kotlin that work flawlessly with the existing Java. By omitting the bytecode, a Kotlin compiler allows the two languages to work in unison in the same project. So, one-liner functions take one line or simple stocks or Java Beans can also be declared in one line. So, real properties generate getters and setters behind the scenes for Java interoperability. Adding the data annotation to a class triggers Auto generations of boilerplate like equals, hash code, two strings, and much more. 

The Terms of Android :-

    we all know that Java is an object-oriented programming language developed by the Sun Micro systems, which is right now owned by Oracle. So being such an old language, Java does a whole lot more than just developing Android app. So, if you know Java, you have a lot more job opportunities. You may not want to develop only Android apps all the time. So, Java lets you spread your wings wider, but if it is specifically about Android app development, so Java is being considered as the most promising language for that. In case of Kotlin, the Kotlin mobile app development community is continuing to grow, and it is right now growing rapidly guys. Back in 2017, Google acknowledged Kotlin by making it the second official language for Android app development. Since then, the programming language has seen a monumental rise in demand in both the developer and enterprise community. With Google announcing that Kotlin is now its preferred language for Android app developers, the language is proving to be a pragmatic, modern, and initiated programming language.  

The Percentage Switching :- 

    Kotlin requires approximately 20% less coding as compared to Java. So, Java will remain essential for Android app development. Switching the entire team to Kotlin at a time can be a bit of a shock, so it is important to do this transition slowly, one person at a time. Having said that, Kotlin is the new official language and owing to its modern nature, it will become widely adopted in the future. So, learning it and starting development with it right now would be a good idea though Java will continue to be a popular language for a long time and isn't likely to be entirely replaced, so take your time and make the switch gently because at the end of the day, it's all about what you feel comfortable with. So, to be a true Androidian, you must have a proficient knowledge or I would say a proficiency in hands-on with Java Android development. 

    I have a question for you here on your program there are two codes for hello world and which one of these code is related to Kotlin the first one or the second one do let us know your answer in the comment section below so guys I hope this article was helpful for you if you re further queries comment down below we'll reach out to you immediately thank you so much for giving us a precious time Read More article's about Java, kotlin, Python and many more.
