Java is both an object-oriented programming language and a software platform. Developers value Java because it is portable across platforms and adaptable to a wide range of contexts. If you already know how to use Java, consider learning JavaScript, HTML and CSS, or Python. If you’re looking to learn Java because you want to be a Web Developer and use Java for your back-end work, you’ll also want to know JavaScript and HTML and CSS so you can transition to full-stack development. If you’re interested in data science, you’ll want to make sure you pick up Python. For Mobile App Developers, both JavaScript and Python are extremely useful. We’ll cover JavaScript, HTML and CSS, and Python below so you have a clear understanding of what skill you want to tackle next.

What is Java?

Java is both an object-oriented programming language and a software platform in itself. Its creators designed it as a “write once, run anywhere” tool. It is portable, scalable, and adaptable. An app created in Java can function across multiple platforms and over distributed networks. This flexibility makes the Java language widely useful and Java coders highly desirable to employers. Professions that use Java include Web Developer, Mobile App Developer, User Experience Designer, Data Scientist, Game Designer, and Laboratory Scientist.

Java’s modular nature allows developers to take existing pieces of code that are useful to them and then combine those modules in a new context for a new purpose. Also, programs in Java do not need to be compiled because the virtual Java Runtime Environment tool interprets the code and translates it for the computer you are using. Java’s portable and adaptable nature allows it to serve a wide range of use cases. For this reason, it has become the chosen tool of key players in the technology space: for example, the Android operating system is based on Java code. In addition to being critical for mobile app development, Java is also a crucial skill for Web Developers. It is also used for data science, game design, user experience design, and scientific applications. Many employers are eager to hire Java coders because the language is highly flexible, with many possible use cases and adaptations to new contexts.

What Can You Do with Java?

Knowing Java means you can code across multiple operating systems and hardware architectures without modifying your programs for a new environment. Because it is an object-oriented programming language, Java allows you to create modular units of code that you can reuse in any Java program, even across platforms and environments. You can quickly adapt code created for one use case to apply in another, as Java is highly flexible and adaptable for novel contexts. So as exciting new technologies arise, your knowledge of Java will remain relevant and desirable to employers.

Using Java also speeds up the development cycle. This is due to its unique interpretation process, which allows developers to sidestep much of the routine testing and debugging necessary when coding in other programming languages. You can use the Java Runtime Environment to keep your applications robust with its automatic memory management. The JRE also supports robust graphic interfaces through multithreading. Another advantage is that its built-in virus and tamper protection keeps your code secure.

With Java, you can build mobile applications for the Android platform and, in some cases, for iOS. If you’re into big data, you can use Java to analyze large datasets with open-source tools like Hadoop and Spark. Java’s “write once, run anywhere” functionality makes it perfect for writing cloud-based applications and powering data collection within them. Though machine learning is typically associated with Python, libraries such as Deep Learning for Java and MLib make it easy to take advantage of Java’s speed and security by providing a stable environment for deep learning or machine learning processes. Another great application for Java is programming smart household devices. Java is also useful for game design, both mobile and desktop.

JavaScript

JavaScript is a language used for front-end web development and mobile app development. If you want to become a full-stack Web Developer and are learning Java for back-end development purposes, you’ll also want to learn JavaScript for front-end development. Want to become a Mobile App Developer on the Android platform? Learning Java is a great start! And adding JavaScript will broaden your potential employment options.

HTML and CSS

HTML and CSS are the markup and style sheet languages that instruct your browser on how to display the visual elements of a website. Both are essential for front-end web development. To become a Full Stack Developer, you’ll need front-end expertise as well as a knowledge of back-end skills like Java coding.

Python

Python, another object-oriented programming language, is increasingly important for data science. (Object-oriented means that Java and Python are organized around “objects, ” units of code that programmers can reuse and combine in a modular fashion to serve different purposes.) Python is generally considered a little easier than Java, so you’ll likely be able to pick it up quickly once you’ve studied Java. Taking classes in Python will make you a strong candidate for Data Scientist roles. Mobile App Developers also frequently use Python in their work.
