7 Tips for Working With Java

    Java is one of the most popular programming languages –it has been so for so long. According to Tiobe Index, Java rates as the most popular language among programmers, followed by C. It has a popular user interface that makes it suitable for Object-Oriented Programming (OOP).  We can also attribute its popularity to its use of a simple and efficient approach to various programming tasks and to giving convenience to programmers. Many devices, from cell phones to cars and refrigerators, work in Java. It just shows you how learning and becoming proficient in Java can put you at an advantage with potential employees from any industry. The competition is fierce. You need to set yourself apart from other programmers by acquiring sufficient knowledge and familiarizing yourself with many concepts to stay ahead of your competitors. It’s crucial you stay relevant by continuously learning and staying up to date with the ever-changing technology. The question then remains how you can learn Java and become a competent Java programmer. Don’t worry! There are various ways to learn Java. You can learn it by yourself using the many reference materials and tutorials available on the internet. College or university students studying computer science or other IT-related courses also get the chance to learn Java. Besides college and learning by yourself, you can learn Java skills through an apprenticeship involving pre-training and opportunity placement to kickstart your career in tech. While any willing individual can learn and sharpen their Java skills, knowing your way around working with Java makes you a more competent programmer. This article explores some tips for working with Java as a beginner to make you stand out among your competitors. Let’s get into it!

1. Write Code Yourself With Java

As an individual who wants to learn Java, it’s advisable to write the code yourself. Don’t be like many people who want to learn Java by copying code from the internet and executing it –you’ll be doing yourself an injustice, and you won’t learn much. While using the internet for Java learning materials and tutorials isn’t wrong, understanding the fundamentals, practicing, and writing the code yourself is the best way to learn. Writing the code yourself doesn’t mean constantly coming up with brand new stuff. It will help you master Java basics. Some codes from the internet might have mistakes or errors. By writing code yourself, you will avoid any mistakes that the original author of the code from the internet might have made. Use the internet sparingly as a source for reference material. Don’t copy executable code directly if you want to learn Java. Another mistake that beginner programmers make is “just reading” Java. They’ll read books, view YouTube videos, and assume they’re learning code. If you’re doing it for the sake of acing your exams, then it’s fine. You have to get your hands dirty if you want to become a competent Java programmer. Ensure you learn and apply. Implement everything you read by writing code.

2. Understand Your Code, Data Structures, and Algorithms

Remember, everyone starts from somewhere before they can become seasoned Java developers. Before anything else, it’s important to understand the concept behind codes, algorithms, and the compiler process. One of the best ways to achieve this is by writing the code on paper –it’ll help you understand everything better. While this might seem like a far-fetched idea, even expert developers use this strategy to solve complex problems. Once you have a perfect understanding of everything, you’ll be confident to write longer, more complex code with minimal errors. Since you’re likely to be working with companies, making a Document of Understanding (DoU) and getting it validated before writing any code is important.

3. Learn the Basics of OOP Principles

As mentioned earlier, Java is the most suitable language for object-oriented programming. It’s actually an object-oriented language. It means whenever you are developing Java applications, you are writing object-oriented code. You cannot learn and perfect your skills when working with Java without gaining deep knowledge of the OOP concept. As a Java programmer, you need to learn how to apply OOP principles and be knowledgeable enough in inheritance, object modeling techniques, SOLID principles, design patterns, and other OOP-related concepts.

4. Learn the Essential Java APIs and Libraries

Java, being the world’s most popular and advanced programming language, has many sets of standard libraries and APIs for developing almost everything. Although you aren’t expected to know all of them, it’s best to know some of the key and frequently used APIs and libraries. These libraries make your work as a programmer more effortless and more efficient. They also provide an organized flow to your code, allowing you to track your progress and identify errors easily.

5. Set Aside Memory for Objects Creation and Avoid Creating Objects Unnecessarily

Setting memory aside is crucial for any programmer and not only those working with Java. You must allocate memory with the “new” keyword when creating code since Java is a dynamic programming language. Failure to allocate memory with the word keyword “new” will throw a null pointer exception. Again, whenever you create an object in Java, it uses your computer’s system memory. It’s important to create objects only when you need them to avoid depleting your computer storage.

6. Always Test Your Code

Testing enables you to find any issues or errors in the code you wrote. Java has the Junit framework, which you can use for unit testing. It’s always advisable to write a Junit test for every code you write.

7. Write More and More Code

The things you can learn about Java are inexhaustible. You should endeavor to keep learning by writing more code. This language becomes interesting as you learn, provided you remain interested, creative, and motivated to learn and become better. By putting what you’ve learned to test and practice, you’re sure to become a competent Java programmer.
