Beginner’s Guide

What Is Java? 

Java (not to be confused with JavaScript) is a general-purpose programming language that was designed to run on a wide variety of devices, ranging from smartphones and PCs to smart TVs. According to the Stack Overflow Developer Survey, Java is the 5th most popular programming language, right below SQL.

Although created back in 1995 by Sun Microsystems, the Java programming language is still popular today. Java is like a simpler version of C++ that takes many design cues from its predecessor, Oak. Java’s slogan, “WORA,” is an acronym that stands for “Write Once, Run Anywhere.” After the code is written in Java, it can run on any compatible device with Java installed without the need for recompilation. 

To show you what Java looks like, we’ll use the classic “Hello World” example:

class HelloWorldApp {

    public static void main(String[ ] args) {

        System.out.printIn(“Hello World!”); // Displays the text on the screen. 

    }

}

What Is Programming in Java Like? 

Java is capable of object-oriented programming, meaning that it allows you to organize attributes together into objects and classes. Once defined in your program, you can reference them at a later time to save you from writing it all out again. A procedural language, on the other hand, requires you to write out huge lines of code that are dependent on each other. Without the convenience of objects, you always have to restate everything. 

Uses for Java

The great thing about Java is that it is extremely versatile and can be found in just about any industry. In fact, once you’ve learned Java, you will never run out of uses and applications for it. The most common uses for Java include web, mobile, and desktop applications. 

Mobile

Android applications can be created entirely in Java, meaning that you can become an Android developer with a good knowledge of Java. 

Web

Although websites are made up of HTML, CSS, and JavaScript, web applications are made up of various different components that can be written in multiple programming languages. Many web applications rely on server code written in Java. Java also supports the creation of Applets, which are small programs, like games, that can be run directly in the browser.

Desktop

In line with its “Write Once, Run Anywhere” philosophy, Java can be used to power desktop applications on multiple operating systems, such as Windows, MacOS, and Linux. While Java is not truly native to any platform, there are plenty of tools that allow you to run Java on any operating system. Oracle, the company that bought out Sun Microsystems (the creator of Java) offers developer tools for writing Java programs on various platforms.

Enterprise

Not only is Java a programming language, but it’s also a platform. Java EE, or Java Enterprise Edition, is a special version of the Java platform designed for business applications. Java EE is often used for large-scale networks and comes with a higher level of security for corporations. 

Servers

Last, but not least, we have Java for servers. In addition to Java EE, Oracle offers Server JRE, which is a Java platform designed specifically for servers. JRE stands for “Java Runtime Environment”. 

How Much Do Java Programmers Make?

According to Payscale, Java programmers based in the U.S. make an average of $72,611. As you might already know, U.S. programmers are some of the best paid in the world. 

Even though you may make substantially less in your own country, you’ll still gain incredible earning potential by learning to code in Java—no matter where you live in the world. Java programmers in places like Malaysia, for example, can make up to 1,200% more than the average national salary in their country). Not bad. (See the data here: Java Developer Salary: Local & Worldwide Comparison Infographic).

How Do I Learn Java?

Due to its huge popularity and high demand, there are plenty of online and offline java tutorials available to help you start learning. To find out more, check out our article, “How to Learn to Code”.

How Long Does it Take to Learn Java? 

The amount of time it takes to learn a programming language depends on the methods you use, your learning retention, and how many hours you invest per week. You can’t expect to know everything about Java after taking a semester-long course at your local university or a 14-week program at a coding bootcamp. However, depending on your dedication, the basics you need to develop a good foundation can be learned rather quickly.

Is Java Right for Me?

One of the best things about software development is that there is a wide variety of languages out there. If you simply despise programming in C#, for example, there are plenty of alternatives to choose from. The education never really stops. 

For most, Java is a good place to start, because it allows you to program for a wide variety of devices and applications with just one single language. 

However, if you’re just getting started in programming and are unsure if Java is right for you, please check out our article, “Which Programming Language Is Right for Me”.
