Key Highlights and Learnings in a Java Programming Course

Java: The WORA (Write Once, Run anywhere) Program


Java can be found everywhere, from supercomputers to laptops, from mobile phones to gaming consoles. It is the core of the digital domain. It is so vital and indispensable that many websites and applications will not function if Java is not installed on the machine. Though developed about 20 years ago, it is still relevant as it has been constantly upgraded.

Java enables the developer to create top-level and sophisticated applications for cross-platform interactivity. Due to the availability of applications across diverse platforms, enterprises can enhance communication with the users, extend more services and collaborate easily. When talking about Java, we must understand that it has absolutely no relationship with JavaScript; they just share identical names.


Key Highlights and Learnings in a Java Programming Course


What are the key features of the Java programming language?

One of the best features of Java is that it is an all-purpose language. Hence it can be used in various environments to design some of the best applications, be it Mac, Unix, or a cell phone. Let us have a look at some of the merits and features of the Java programming language:



Java Programming Course


  • Uncomplicated and simple

Finding SQL and other programming languages a bit complicated? Go for Java. It is a learner-friendly language that allows you to make mistakes while learning, granting the users the liberty to specifically concentrate on programming rather than complex machine elements. Java has minimal magic characters and easy syntax like English, making learning and reading easier. It is object-oriented, which makes its system modular and flexible.


  • A widely-used programming language

Even though SQL, Python, and other programming languages have become popular lately, many prefer Java. Being user-friendly and easily accessible, it is used by the majority of information technology and software companies, like Google, LinkedIn, Facebook, Twitter, and Netflix, to name a few. Besides, it is regularly updated to meet the industry's needs. 


  • Multipurpose and versatile

Highly adaptable, expansible, and most importantly highly transferable, Java is known as the ‘write once, run anywhere' language. When a Java developer writes code once, it can be moved easily to any other device, making it a preferred programming language for mobile applications and computers to game consoles and the internet. 


  • A precursor to other languages

Java being a fundamental language, learning it makes it easier to understand the basics of Python, C, C++, and so on. Java helps one develop logic and test out ideas. Hence it is commonly taught in many computer programming institutes.


  • Open-source and secure

One of the key features of the Java programming language is that it is an open-source language. There is no need to pay any charges while writing a Java application. There has been some confusion over it being a paid service; however, there are two versions, Oracle JDK and Oracle open JDK. Oracle open JDK is free and can be used by anyone, whereas Oracle JDK is paid. The absence of manual memory administration makes some security mistakes and breaches impossible, ensuring security. 


  • Boosts employability 

Want to shop, book movie tickets, or need to satisfy hunger pangs? Your smartphone has the answer. As more and more functions are shifting to smartphones, the demand for Android apps is multiplying at an incredible speed. This brings in a lot of career opportunities for Android app developers as these apps are written in Java. Java developers are highly in-demand professionals and are one of the highest-paid developers in the industry.

  • Community support

Being a widely used and mature programming language, Java has innumerable resources to learn from. Many user groups, forums, and open-source libraries work to solve your doubts about Java.
