TRUTHS AND MYTHS OF JAVA

 INTRODUCTION



JAVA programming language, released in 1995 is a High level programming language and is used by more than 6.5 million developers. The object-oriented language is simple and easy as it derives much of its syntax from C and C++. It is globally supported programming language, which has committed developers who are trained to catch bugs quickly and fix them. The demand for java professionals is high across the globe. Let us bust the truths and myths related to java programming language.


TRUTHS AND MYTHS ABOUT JAVA PROGRAMMING


                                     


 

1)JAVA is relatively very slow as compared to C applications

   Initially the java virtual machines were slow and hence java was slow as compared to C applications. However, the speed difference between Java and C/C++ languages is now not a major concern due to technologically advanced virtual machines and just-in-time compilers that allows faster loading.

2)JAVA is better than C++ and more in demand

   While it is true that Java is the dominant language in the software industry, the fact cannot be negated that it cannot overcome certain narrows and specific tasks, such as artificial intelligence. Yes, Java has phenomenal growth and is in more demand than C++, there is still room for other programming languages. Java is excellent in portability and internet support, C++ excels in performance and works on various operating systems. So both have their positives and negatives and professionals with the knowledge of either can make it big in the IT industry.

3)JAVA programming is Easy

   There is a half-truth here. Programming can be easy and it can be really difficult. It really depends on the indivisual. But a real problem arises when you have the wrong idea about programming. Some people think, programming is nothing but writing if-then-else statements  and if you get the hang of them, you can master any programming language under the sun. Sorry to burst the bubble but programming is much more than these statements. In fact, programming and we are talking about awesome programming which is a touch cookie. It takes years  to become a developer skilled in programming and it requires a special sort of commitment and passion to become a programmer who knows the ins and outs of some of the most popularly used programming language.

4)JAVA is a super-programming language 

   Yes, Java is an object oriented programming that you absolutely must learn and C is general purpose language that  must be in your armory. No doubt about it. But, experienced developers know they need to be up to speed in a collection of programming languages, otherwise there is a very real danger that their applications will be founding wanting in some area or other. There is another truth that needs to come home – there are no super programming languages just super programming. Searching for a super programming language means you are trying to look for an easy way out. There are no shortcuts in programming.

5)JAVA language has become 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.

The idea that all languages become outdated is wrong. The best languages, especially the ones that are commonly used in programming, evolve to meet the changing needs of developers.


6)JAVA does not support multiple inheritances as a class can implement multiple interfaces

With java 8 this has now become debatable. Interface implementation facilities partial interfaces (i.e only  default methods from java8.). Java does not support multiple class inheritance. Though an  interface can extend multiple interfaces.

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

7)JAVA applets can pursue your hard-drive and erase documents

                                        


                                                     

   Any attempt by an applet to get to nearby documents will toss a security exception. On the off chance that uncaught, the applet will crash, however no document access will happen.

   The main special case to this standard is for digitally marked applets which might be conceded for extra benefits. Your program will show a discourse box, inquiring as to whether you need to acknowledge the character of the applet creator. Pick no if uncertain and you'll generally be shattered.



                      

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.

IMPORTANCE OF LEARNING JAVA

1)It is the most commonly used programming language in the world. According to oracle, 3 billion devices run on Java. The TIOBE programming community index is updated monthly and regularly lists Java as the most popular programming language.

2)It's a good precursor to learning other programming languages(like C, C++). For those in favor of learning Java first, a key factor is that it teaches you to think like a programmer. You’ll learn the language, but you’ll also learn some key underpinnings of programming as well. It’s also an object oriented programming (OOP) language. Learning OOP requires students to master a certain level of logic. 

3.It's a mature language. Java is 22 years old (Java 1.0 was released in 1995). In other words, in the programming world, it's been around for a long time. So, basically if you're new to programming or just new to Java, nearly any problem that you will run into has been run into by someone else. Any question you can ask has already been asked, answered, and posted online in some programmer community. There are loads of resources available to help you if you get stuck on a task.

4.We can find lots of like-minded, passionate programmers. Because it’s been around so long, there are lots of Java practitioners. If you check Meetup, there are 1,751 meetups worldwide, with 886,056 members, including our own Zip Code Wilmington Meetup. Here are other places to check:

 

CONCLUSION

 

      Java language is much more reliable and holds much more potential than many people realize. It's more than just a language, Java software can run inside as well as outside of it. Despite all the complaints about Java that it is slow and confusing it is in the list of top 5 most popular programming languages in the current scenario, and another side of that complaint about it are just myths and misconceptions of people.

          Java is an excellent tool to create programs and few myths shouldn't stop anyone from relishing its benefits that much greater than the misconceptions such as Java developer's average salary in India is around 4.5 Lakh per annum so it pays to be a Java developer. So in this blog, we tried to show some reality of Myths and explained to you some interesting facts that will help you if you are looking forward to Java.

       We hope that this blog helped you in some way, share your word in comments about the myth or fact that amazed you!
