Java has been extensively employed as a general programming language by top corporations and as a teaching language in universities and institutes during the last few decades. Java is one of the most actively used programming languages in the world, and it is used to construct a wide range of cross-platform applications and software. Java is an evergreen language that has benefited the industry for quite some time due to its flexibility with a wide range of other languages and platforms. It is the most popular programming language of all as it has been placed first in the most recent TIOBE index for January 2019. Java is an evergreen language that has benefited the industry for quite some time due to its flexibility with a wide range of other languages and platforms.
Owing to such advantages of Java, it’s critical to debunk some of the most widespread misconceptions about it.
1. JAVA is outdated
With the introduction of new technologies and languages, one misconception that has plagued our understanding of Java is that it is obsolete and no longer relevant in the IT business. In reality, Java is a key language that anybody interested in a career in the IT industry should learn. Java is the most popular programming language in the world today, and it is utilised by some of the world’s top brands in a variety of sectors.
2. JAVA is not safe
There is a pervasive myth that Java is unsafe. Most programmers and developers believe that an applet can be introduced through a web page and can compromise or remove vital files without warning. Thankfully, it is a flawed concept. When an applet attempts to access local storage or a hard drive, the program terminates owing to a security violation. Even if the applet is digitally signed, when it attempts to access the hard drive or storage place, the user’s permission is sought. A security pop-up appears to question if the user is familiar with the signing process. If the user is doubtful, she can select the “no” option, which will terminate the applet.

3. JAVA is too slow
This would have been accurate several years ago when Java was still in its formative stages. However, throughout time, the language has evolved and expanded, leaving behind lags. Today, Java is known for its excellent performance and is the programming dominant language for developers all over the world. This also emphasises the fact that students all across the world are learning Java programming to pursue rewarding career opportunities.
4. Core JAVA is not relevant
Many students who endeavour to work in the IT sector enrol directly in advanced Java classes and bypass the Core Java training program. In reality, this is a mistake to make because Core Java lays a solid foundation of knowledge that will eventually serve as the cornerstone for your profession. Missing out on this results in poor comprehension of the fundamentals of the language, which might have a negative impact on their jobs in the long term. So, if you want to study and create a profession as a Java developer, start with the Core Java course. If you are keen enough, there are many online courses available to enrol yourself in.
Relying on magical thinking can leave you unprepared for situations in the real world. Hence, it becomes necessary to debunk myths even if they tend toward the negative.
5. Memory leaks do not happen in JAVA
If you have previously dealt with other programming languages such as C and C++, you may believe that memory leaks in a certain way. When memory spaces are allotted differently in other programming languages, some memory leaks and the application loses its capacity to store data effectively. This sort of leak is highly unlikely in Java because objects are readily accessible, but it does not rule out the possibility of memory leaks. Memory leaks in Java only occur when a programmer becomes lazy and fails to clear up objects and other variables that are no longer required. The apps begin to use memory until it is depleted. Even if memory leaks are less possible, it is critical for a programmer not to get complacent.

6. JAVA alone would suffice your needs
People who believe Java is the only programming language they will ever need are wrongly conceived. Most things can be built with skills, expertise and Java’s extensive libraries. However, you may have to consider using another language for that portion of your work. For example, if you need to design particularly performance-sensitive apps, Java alone might not suffice. Also, if it comes to controlling hardware effectively, there aren’t many Java libraries and packages that can assist you to do a lot of direct hardware programming. Therefore, be prepared to delve into learning other languages holistically, too, if necessary.
Myths emerge in the minds of all individuals when they lack sufficient knowledge or rely on the untested opinion of others. As a result, it is worthwhile to study how everything works for oneself. In terms of programming, you must commit yourself to it in order to get the desired results, and there is no doubt that the Java programming language is an excellent place to begin your journey into the world of IT. None of the myths are true in the versions of Java that are currently operating on hardware. It is possible to write incorrectly and develop a terrible application with Java, but this is true of practically all programming languages. If your application or software is sluggish and unwieldy, look to the programmers and developers who produced it, not Java itself.
