Myths and Facts of JAVA

 

  MYTH BUSTERS AND FACTS IN JAVA

  

           Java, despite being the seasoned veteran of object-oriented programming languages still remains immensely popular for many good reasons. In fact, many programmers swear by the stability of Java. It is one of the most structured languages, being the go-to for millions of software developers around the world.

        Java evolved as a good choice for developers because of its unique structure and its capability of operating similarly on a variety of  hardware or software operating systems. It is one of the most secure, simple, and robust programming language was first released to the world on May 23, 1995.

        In this blog, we will be discussing some common Java programming language myths that are mostly perpetuated by misinformation or simply lack of knowledge. We will also be going through some interesting facts for many of you who may be new to Java! 

1)JAVA IS A CONFUSING LANGUAGE 😕

            By saying that Java is confusing you can understand many different things. One of the things which make people believe that Java is confusing is that there are Java and JavaScript and they do not see the difference. The fact that they are called similarly doesn’t mean anything because Java is a programming language and JavaScript is a scripting language for creating different things such as HTML documents.

          The second issue by which Java is considered to be a confusing language is the fact that although it is the language which is most often learned at the beginning of one’s programming path it is not the simplest language. For example, Python, C#, or Ruby is much simpler than Java, while C and C++ are more difficult.

2)Java Is Slow

        This myth dates back to a very early time when Java could be understood as slow, but it was the beginning of programming languages and this judgment is no longer accurate. Everything has changed since Java Virtual Machine was introduced. In the past Java, speed was compared to programming languages such as C or C++, but that’s already history. 

        Additionally, when the JVM JIT compiler was added, the ordinary programming language has turned into a real ecosystem, which is currently very fast.

2.   Java and Kotlin have similar performance indications  and are the best options for Android development.

By graphs, we can say that java is the fastest among other languages used for android app development. So it is not slow but also one of the fastest programming language for Application Development.

3)JAVA IS OUTDATED

            If something is on the market for as long as Java is probably already outdated! Many people come to such conclusions, however, this is a mistaken view. Just because the name hasn’t changed in so many years doesn’t mean that nothing has changed in Java.

          During the first years of the functioning of this programming language. It has changed approximately every two years, and recently, changes have occurred more and more often and implement truly innovative solutions to improve the work of programmers using Java. But since it was taken over by Oracle, the upgrades and functions still allow it to be at the forefront of modern programming languages in the world.

4)Java does not support multiple inheritance 

        With the new and updated Java 8, this has now become debatable. Interface implementation facilitates only partial inheritance ( i.e. only default methods from Java8 ). Java doesn't support multiple class inheritance, which means you can't have more than one parent classes for a single base class. 

        The reason behind this is to prevent ambiguity within inheritance. Consider a case where class B extends class A and Class C and both class A and C have the same method display(). Now in this case, the java compiler cannot decide which display method it should inherit. So, to prevent such a situation, multiple inheritances are not allowed in java.

         However, Java does provide alternatives to  the functionality that multiple inheritance give in languages like C++. Java Abstract classes and Interfaces act as templates which can be used to give the feel of multiple inheritance. As a programmer, you can implement multiple interfaces, but you can still only extend a single abstract class. This added functionality in Java resolves the problem of inheritance ambiguity as well as provides more tools for object oriented programming. 

   5)equals and == means the same thing in JAVA.

     "equals" is the member of the object class which returns true if the content of objects are the same whereas "==" evaluate to see if the object handlers on the left and right are pointing to the same object in memory.

6)Core JAVA is Not Very Important

     A lot of candidates who aspire to make a career in the IT industry directly enroll in an advanced Java course and skip the Core Java learning module.        The fact is that Core Java sets the strong foundation of knowledge that will eventually serve as the base for our career. So if anyone is keen to learn and build a career as a Java developer, first take up the Core Java course. 

7)Java is most popular programming Language

     This myth will be in many people's minds that it is a very popular language because it several application and many of the android applications made using java but it's not fact that it is the most popular language.

According to the chart of most demanded and popular languages in 2021, We can understand that java is in the 5th rank whereas python, java, Html, Css are above java because most of them are scripting language and are quite easy like python although java is not that difficult but still it's in the top 5 list.

1)Java was invented by an accident

    

         It is a true story when, James Gosling was working at Sun Labs, around 1992. Gosling and his team were building a set-top box and started by "cleaning up" C++ and wound up with a new language and runtime. Thus, Java came into the real world.

2)"Java" is not a real name 

    The original name for Java was Oak. It was eventually changed to Java by Sun's marketing department when Sun lawyers found that there was already a computer company registered as Oak. But a legend has it that Gosling and his team of programmers went out to the local café to discuss names and ended up naming it Java. 

3)The most popular user interface

        Currently, about 3 billion mobile phones are working in Java, as well as 125 million TV sets and each Blu-Ray player. This language is continually ranked first in the rankings of software developers as the best choice of programming language.

         Most of the applications are made up with the help of java and its IDE such as android studio like Twitter, Spotify and the most popular search engine Google uses Java APIs.

4)Java does not have Pointers

        The reason behind this is, if the pointers were added to Java it would be compromised with points of security and the robustness that would make the Java more complex such as the "C" programming language.

5)The Word Final is Ambiguous 

        Actually, there are four different meaning of the keyword "Final" in java with respect to field, class, variable, and method which are as follows;

• Final Field: It denotes a field that is constant.
• Final Class: It means this type of class is not extendable.
• Final Variable: If this type of variable gets assigned then it can not be adjusted after it.
• Final Method: This type of method can not be overruled.

6)The 'Duke'

         It is hard to believe but the Java programming language has its own mascot The duke which is a cartoon charactor that represents java. It represents a "software agent" that works for the users. It was created by java's graphic artist Joe Palrang who was popular for working in Hollywood movies. Duke is not only the mascot, after oracle taken java duke is present in all-conference regarding to it to spread happiness and positivity.

               CONCLUSION

       Java is much more reliable and is much more flexible than many people realize. It's more than just a single-lane language; Java software can run on multiple Operating Systems. Despite all the complaints about Java saying that it is slow and confusing, it is in the list of top 5 most popular programming languages in the world,and the first in terms of Object Oriented Programming. Many of these complaints have been debunked, being declared as just myths and misconceptions of people who are not educated enough in the practical applications of Java.

          Java is an excellent tool to create programs and a few myths shouldn't stop anyone from relishing its benefits that are much greater than some complications. An average Java developer earns a salary of around 4.5 Lakh per annum in India, so it certainly pays to be a Java developer! So in this blog, we tried to show other side of the coin to these myths and explained to you some interesting facts that will help you if you are looking forward to learning and making a career of programming with Java.

            We hope that this blog helped you in some way, so please do share your thoughts in comments!

                   Thank You
