When James Gosling came up with an idea for a new and useful programming language, his goal was to create something simple, portable, secure, independent, robust, dynamic, and architecture-neutral. And now, we have Java as one of the world’s most used and functional programming languages. Almost everything you do on the Internet, using your laptop or smartphone, works well because there is a strong Java background.
Currently, there are four active Java versions, including:
- Java Card for SIM and ATM cards or other small processing devices
- Java SE (Standard Edition) for programs for desktop and servers
- Java ME (Micro Edition) to develop programs for mobile devices
- Java EE (Enterprise Edition) for large-scale applications
These versions offer many chances to focus on what seems most attractive to you. Embracing a career as a Java developer is an excellent start for computer scientists but also for those who want to take a different path and grow professionally.
So, you will have to invest some time to master Java. Today, many IT companies are still looking for java developers for hire, which means you have a chance to grab a great job position and become an even better programmer.
How Long Does It Take to Become a Java Programmer?
If you are already familiar with the language, you can practice for 2-3 hours per day and learn new things too. With that, you can expect to learn Java in a year and master it in two years. This is an average estimation and may vary depending on your dedication, expectations, learning skills, and access to learning resources.
How to Become a Good Java Programmer?
You don’t need an university degree for this. You can study computer sciences, but also, you can start learning Java alone, or take some course.
Java is one of the languages with continuous support by a large community, and you can always find suitable resources, literature, and online help. And when you master the language, we are sure you will have better career options. But, there are some things you need to do before that:
1. Learn the Basics of Core Java
Core Java is also known as Java SE (Standard Edition). It’s the best way to get to know the logic, characteristics, structure, and syntax as you get familiar with the whole concept of this language.
Once you master Core Java, you will be able to learn many important things like how to initialize an array in Java or how to reverse a string in Java. Additionally, you will understand the OOP concepts and learn how to properly use APIs and libraries to implement different functions and operations. It seems like a lot of jobs, but these are the basics that will help you become a great computer scientist in the future.
2. Practice a Lot
It’s not enough just to get familiar with Java concepts. Now you have to grab the challenge and practice almost every day. As you keep coding, you will learn how to write simple and complex codes without making some basic errors.
Practicing also includes compiling and testing, so you will be able to detect your weaknesses and work on improving them. After that, you are ready to move to Java Me or Java EE, depending on your aspirations.
3. Work on Mini Projects
You can come up with some unique idea or consult someone to assign you a task. When working on a specific project, even for practicing, you get used to the syntax. You also learn how to use less memory when defining the elements and using functions and discover the real potential this programming language has.
4. Embrace the Needed Skills to Become a Java Developer
It’s not enough to know how to write code in Java. As a developer, no matter the level, you have to know how to create a new project, compile it, and fix bugs. Also, get familiar with some of the frameworks, like Spring and Hibernate, because you will surely use them in the future.
You will also have to learn how to use SQL when using some databases. Most of the time, Java and SQL go together, so you can become an entry-level developer with the potential to grow as a mid-level or senior programmer.
Also, adopt as many management skills as possible because you will have to manage and handle many projects in the future.
5. Don’t Stop Growing
Even if you get your dream job, you don’t need to stop working on your Java skills. If you grow through time, you will have many career chances to embrace in the future. That’s how you maintain your proficiency and get eligible to work on bigger and more sophisticated senior-level projects.
Programmers and developers should always be up to date with the new things in their area of interest. Technology is changing every day, and there is always something new to learn and embrace.
