Learning Java would help you advance in your career and demonstrate your technological abilities. James Gosling created Java and his Sun Microsystems team in 1995, is now one of the most widely used programming languages in technical advancements. According to a study conducted by CodingDojo, it entered the top ten programming languages in 2021 and is ranked second in the TIOBE Index for April 2021.
According to Enlyft survey, the two most important Java firms are Computer Software (18%) and Information Technology and Services (11%). Most Java-using companies (69 percent revenue) are Small (under $50 million), 15% are Large (over $1 billion), and 9% are Medium-sized.
Java is used by 40% of the United States, followed by 7% in India and 6% in the United Kingdom.
According to Developer Economics in 2020, there are more than 8 million Java developers in the IT world. Any programmer would advise you that the global community is critical to their professional development. Any language would not thrive without GitHub project repositories and Stack Overflow.
This is an object-oriented programming language that is interpreted and multi-threaded. As a result, in recent decades, Java has overtaken a host of programming languages. It is, however, a beneficial programming language for developing business applications due to its consistency and usability.
Since Oracle acquired Sun Microsystems in 2009, a rapid upgrade process has been in place to respond to change. After few months, a new version of Java is released, along with recent revisions designed to make the language more responsive to new programming advances and remove vulnerabilities. Oracle has continued the upgrade process since the Sep 2017 release of Java SE 9, and Java SE 16 was released in Mar 2021, with Java SE 17 set to be released in Sept 2021.
Java is used for Web applications, Microservices, Mobile Apps, IoT, Big Data analytics, and Distributed Systems, all of which are expected to grow in popularity over the next decade. In 2021, Java will continue to lead the entire Financial services market, including Investment Banks and E-commerce, and the IT sector.
Job seekers or aspiring programmers may be unsure whether they need to master an old programming language. After all, there are also plenty of new languages and technologies to learn. There are many reasons why Java has become the most common programming language and why it is still worthwhile in 2021.
Simple to Learn and Use
It is simple to learn and use for developers at all levels of experience, and it has a variety of streamlined mechanisms that make it more user-friendly. The garbage collection feature allows programmers to handle memory automatically without writing Java code.
Low Commercial License
For new developers or those using it for the first time, it is completely free to use. As compared to many other deals and discounts, the monthly cost of $2.50 per user for a Java commercial license is relatively low.
Platform Independent
Applications developed in one environment can be compiled into bytecode and run on any other supporting the Java Virtual Machine. This functionality is based on the well-known Java phrase “Write Once, Run Anywhere.”
Developing Various Applications
Java allows programmers to perform any task in the field of technology, such as the exponentially expanding Internet of Things. To build web applications, developers use the Jakarta EE standard, which is the most current J2EE specification within the language. Java is compliant with the most recent approaches, such as AWT, Swing, and JavaFX, to build rich desktop GUI applications.
The IoT (Internet of Things) is quickly expanding, and Java’s usability, adaptability, and widespread availability are being leveraged to build devices that are more effective at sharing and retrieving data. Because of its robustness, security, and cross-platform functionalities, Java is ideal for one of the best Cloud Computing platforms, Oracle Java Cloud Service.
Developing Big Data Technologies
Big data is today’s trend, and Java was used to develop it has contributed to its success. Hadoop is a Java-based big data platform that is well-known and widely used. Scala is a popular Java-based programming language that was created to address the limitations of Java.
Developing Mobile Applications
Java is the primary programming language used by the Android operating system and a large number of mobile developers. Java Platform, Micro Version (J2ME or Java ME) is a cross-platform development environment that lets programmers create applications that run on any Java-enabled computer. The mobile app development frameworks Kotlin and Android Workshop are also compliant with Java. With all of this in mind, not to mention the fact that mobile computing is rising in importance while desktop computing is diminishing over the next few decades, it is obvious that Java cannot be avoided.
Developing Scientific Applications
Java is used for developing reliable, compact scientific applications that involve mathematical functions and analyses. In programming environments such as MATLAB, it is used as part of an integrated system and user interfaces.
Earn A Good Package
Developers should learn Java if they want to work in the IT industry and earn a decent salary. According to a study conducted by Indeed 2021, Entry-level Java developers can expect to receive around $86993 per year in the United States. Java programmers can expect to earn a decent salary since the programming language is commonly used in industry.
Used by Global Companies
Java can be used for many global platforms and sectors on a variety of devices such as laptops, mobile devices, and business applications. Major international companies such as Netflix, Airbnb, Google, Instagram, Uber, and Spotify are only a few examples.
