If you are considering a career in software development, you will need to know at least one programming language. For this reason, many aspiring developers are inquiring on what is java and we’re here to answer just that.
Deciding on which one can be hard because every programmer has a favorite. The reality is the best programming language is the one best suited for the task at hand.
That being said, Java is an excellent choice for beginners. But what is Java anyway? It is designed to be a write-once-run-anywhere (WORA) language.
What is Java?
Java is an object-oriented, concurrent language. It is an all-purpose language that is class-based and runs on any platform and with as few dependencies as possible. The run time code operates in the Java Virtual Machine (JVM) as compiled code.
History Behind The Language
James Gosling of Sun Microsystems, along with his team, developed the first version in 1991. It was designed to run a variety of computer processors that controlled home appliances. In 1994, Gosling realized that the language would be ideal for web browsers. That connection has stayed with Java as it is often considered the language of the web.
According to legend, Java was originally called Oak until it was discovered that a programming language already existed with that name. Traditionally, the developers of a language name it, so Gosling and his team were forced to find another name. After hours of brainstorming, the group went out for coffee — and Java was born.
Why Learn Java?
You may have heard that it’s old school; that it is going away as a programming language. Well, it’s not. According to the TIOBE’s January 2020 programming language index, Java is the top programming language, followed by C and Python. The top two languages have been around for 20 and 50 years, respectively. The age of a language doesn’t make it obsolete.
It’s Not Just For Web
From the beginning, Java has been associated with the web. It has become the go-to language for server-side development projects. Recently, it has become the primary language for developing Android apps. It executes faster with fewer bugs, and it is backwards compatible with early versions. Backward compatibility is critical for business applications. Without it, programs would have to be rewritten after a new release and the most current is version 8.
Easy to Learn
Not everyone would agree that Java is easy to learn, but it is. Why? It’s simple. It doesn’t require high-level math, and it is logic-based, which makes it easier to follow. The language reads like English, and it minimizes the use of special characters. Additionally, when it is compiled, it is easier to locate errors.
Since it has been around for 20 years, there is a wealth of information to help you understand the language. There are lots of Java libraries and a stable framework. There are even code samples to guide you through specific implementations. Java programmers represent a powerful online community that can help answer questions.
Programmers Are Needed
Java programmers are still needed for server-side development. They are also in demand for creating mobile applications under the Andriod operating system. The median salary for a web programmer was $84,280, but the annual salary can range from $82,000 to $100,000. The difference in pay depends on whether you are in software development or programming.
What Do Java Programmers Do?
Computer programmers write and test code that lets applications function correctly. Programmers may test applications and programs to ensure they work as designed. If not, computer programmers locate the errors and correct them. Programmers typically do the following:
- Write programs
- Update existing software applications
- Enhance existing programs
- Test programs for errors
- Correct coding errors
- Create and test code in an IDE
- Use code libraries to simplify the writing
In some areas, the work of programmers overlaps with those of software developers. When that happens, programmers may take on the responsibilities of developers, such as program design, model creation, documentation, writing and debugging code.
Who Uses Java?
Despite what you read, many companies, especially those in the financial sector, use the language including:
- Capital One
- JP Morgan
Plus, there are numerous software development companies that specialize in Java development. Your career choices are not limited if you’re a programmer of this type.
A Passion for Change
If you’re ready to begin a career as a Java developer, there’s no better time than now. The demand for Android-based mobile apps continues to grow. Server-side projects for the web aren’t going away. Plus, large corporations such as Microsoft or JP Morgan have large code databases that must be supported. If your passion is computers and you’re ready to change, we are available!
